Abstract:

This The main objective of this study is to evaluate the feasibility of using Permeable Reclaimed Concrete (PRC) for urban roads construction. The PRC can be used at both stabilized base and wearing surface layers for new constructed pavements. The purposes of this paper were focused on the comparison of cost and energy consumption in both material production and pavement construction stages between PRC pavement and conventional hot-mixed asphalt (HMA) pavement. In addition, the potential ecological advantages such as reducing urban heat island effect as well as enrich groundwater table by using PRC pavement in the urban roads was also discussed. The results showed that the PRC pavement could effectively reduce 3 to 5°C surface temperature compare to conventional HMA pavement.

Abstract:

Double-layer paving technology, which is a new technology for construction asphalt pavements, has received increasing research attention for several years. However, few studies have focused on the effect of asphalt pavement layer thickness and mixture-type combinations on the fatigue properties of a double-layer pavement. Therefore, the fatigue properties of the double-layer and traditionally paved asphalt pavements were studied in this work. The effects of two paving technologies, three mixture combinations, and two asphalt layer thickness combinations on the fatigue properties of asphalt pavements were studied through bending beam tests, and a fatigue equation of different asphalt pavements was established using the two-parameter Weibull distribution. Subsequently, the fatigue lives of different pavements were compared and analyzed under the same cyclic load. Results indicate that the flexural strength and fatigue life of the double-layer pavement increased by at least 10% and 54%, respectively, compared with those of a traditionally paved pavement structure. The goodness of fit of the equation established using the Weibull distribution exceeded 0.90. For the traditional paving technology, compared with the pavement structure combination of 4-cm AC-13 surface layer/6-cm AC-20 bottom layer, the fatigue life of a 3-cm AC-13 surface layer/7-cm AC-20 bottom layer can be increased by at least 8%, while the fatigue lives of other pavement structures are reduced significantly. The results also indicate that the fatigue life of the double-layer pavement structure with the 3-cm AC-13 surface layer/7-cm AC-20 bottom layer can be increased by at least 114% compared with that of the traditionally paved pavement structure (4-cm AC-13 surface layer/6-cm AC-20 bottom layer). Additionally, the fatigue lives of other pavement structures can be improved. To effectively improve the fatigue life of an asphalt pavement, a double-layer pavement structure with the 3-cm AC-13 surface layer/7-cm AC-20 bottom layer combination is recommended.

Abstract:

Construction of modern and durable asphalt and cement pavements requires high quality materials and suitable technologies that take into account sustainability concerns which are related to the environmental protection, mitigation and compensation for road construction effects on surface water and groundwater, soil, air, wildlife, landscape, vibration and noise. The objectives of this paper are to identify possible development directions of materials and technologies in road construction in the time perspective of approximately 30 years. In order to achieve that goal a nationwide Delphi survey with 150 invited experts was deployed. The study concluded that binding materials with improved viscoelastic range – and often with specific modifications – would continue to play a leading role. Furthermore, technologies that enable monitoring the state of road pavement condition in a continuous manner would be used to a greater range. Introduction of sensors into the pavement network would lead to the construction of “smart” roads while spreading of nanomaterial technology would improve the durability and reliability of road pavement construction.

Abstract:

Through the analysis and summary of research status and development trends of deck pavement technology of long-span continuous rigid frame bridge deck pavement at home and abroad, the impact factors of durability of continuous rigid frame bridge deck pavement, such as design flaw, constructional quality and overload are studied. This article will comprehensively analyze the cause of disease focusing on mechanism, structure design deficiency and classification method. Analysis shows that: the durability of continuous rigid frame bridge deck pavement is determined not only by pavement material strength, but also by pavement layer thickness and materials of bridge deck. It is integrated design of pavement and bridge deck, superior construction quality and craft that make sure deck pavement durability. Besides, there are still some imperfections and unreasonableness in existing literatures using finite element calculation of continuous rigid frame bridge deck pavement. In order to provide more credible data for future engineering practice and relevant standard, the finite element method and boundary conditions should be studied and improved.

Abstract:

There are two technologies for road construction, e.g. an asphalt one and a concrete one, that exist in the market of road infrastructure at the moment and they both have their advantages and disadvantages [prof Jan Deja of Krakow Mining Academy, Cathedral of Building Materials Technology].The advantage of concrete pavement consists of the fact that it doesn’t require bigger financial expenditures within 10 – 20 years of exploitation (provided that necessary pavement maintenance treatments are carried out). In the case of asphalt pavement it is necessary to mill the wear off layer of the road already after 6-7 years. It leads to the question: which of these technologies should be chosen, which is better? The work hereby carries on analyses concerning a comparison of the technologies for road constructions; the asphalt one and the concrete one. Based on the analyses carried out with the use of the Hellwig method it was found that the achieved values of synthetic meters for asphalt and concrete pavements are close to each other, which may indicate that both technologies are comparable within the sectors taken for analyses in relation to accepted technological-technical and usability features.

Abstract:

Abstract Asphalt mixtures are commonly used for the pavement construction for national roads with a high traffic load, as well as local roads with low traffic load. The constructions of local road pavement consisting of thinner, more flexible layers located on less stable subbase than the pavement of national roads, require reinforcement with asphalt layers characterized by increased fatigue life. Technologies that allow quick repairs and reinforcements, while improving the durability of the road pavement are being sought. Such technologies include the use of modifications of asphalt mixtures with special fibers. The paper presents the results of investigations of the properties of asphalt mixtures modified with innovative basalt-polymer fibers FRP. On the basis of the obtained test results according to the Marshall method, stiffness modulus and fatigue durability, the technical properties of asphalt mixtures with FRP fibers addition were improved. This technology significantly increases the fatigue life of asphalt concrete dedicated for repairs and reinforcements of road pavements.

Abstract:

In recent years road construction is a subject of dynamic changes. The main challenge for designers and technologists is to develop durable and environmental friendly road technologies that can be successfully applied on natural valuable areas. The paper presents selected modern material and technological solutions used for road pavements on areas under special protection (eg Natura 2000). An example of modern environmentally friendly solutions in road construction are: asphalt pavements with the addition of rubber from used car tires, asphalt mixtures with reduced emissions of volatile substances, “quiet” pavements, pavements from recycled materials and from local materials, “biologically active” pavements (permeable mineral layers). Modern and ecological pavements are the important part of science activity of Warsaw University of Technology. New ongoing project is designed to identify the main directions of technological development of road construction in the next 30 years, with a particular emphasis on the sustainable development and environmental protection. As a part of the two ongoing projects, test sections of pavement have been completed. One of test sections with the addition of crumb rubber and the second one as a “quiet” pavement. For the next years, the sections will be monitored.The proper selection of materials and technologies on natural valuable areas does not deteriorate the durability of road pavement, comfort and safety on the roads and at the same time it can improve environmental safety without interfering with the functioning of valuable ecosystems.

Abstract:

Low-volume and unpaved roads constitute the majority of the road network throughout the developing and developed world. Upgrading these unpaved roads to conform to standards of low-volume flexible asphalt pavements is a costly exercise. In most instances, this involves constructing an entirely new pavement base. Recent technological advances in the field of deep in situ recycling have provided pavement engineers with an alternative to standard rehabilitation and reconstruction methods of flexible pavements. One such technique of stabilization is foamed tar treatment of inferior natural pavement materials through the application of deep in situ recycling to produce a stabilized base for lowvolume flexible pavements. Foamed tar technology and the concept of deep in situ recycling, and its advantages over current reconstruction methods, were reviewed. Health aspects relating to implementation of the stabilization process were addressed with respect to the use of gasifier tar in a controlled recycling environment. The engineering properties of foamed tar mixes were compared with existing stabilization techniques. A test section was constructed with particular attention to the flexibility of foamed tar for placement time, workability, and durability to environmental conditions. Performance testing results were analyzed. In conclusion, the benefits of foamed tar stabilization for developing an improved road network in a cost-effective manner were evaluated.

Abstract:

Pervious pavements are sustainable urban drainage systems already known as rainwater infiltration techniques which reduce runoff formation and diffuse pollution in cities. The present research is focused on the design and construction of an experimental parking area, composed of 45 pervious pavement parking bays. Every pervious pavement was experimentally designed to store rainwater and measure the levels of the stored water and its quality over time. Six different pervious surfaces are combined with four different geotextiles in order to test which materials respond better to the good quality of rainwater storage over time and under the specific weather conditions of the north of Spain. The aim of this research was to obtain a good performance of pervious pavements that offered simultaneously a positive urban service and helped to harvest rainwater with a good quality to be used for non potable demands.

Abstract In recent years, due to the destructive and unproductive character of pavement specimen extraction, pavement maintenance technology intensified the use of non-destructive techniques for pavement evaluation which resulted in the development of several devices and evaluation methods. This paper describes the use of technology based on low frequency ultrasonic tomography for evaluation of concrete pavement parameters. The equipment was applied in three experimental sections with different concrete pavements built at the University of Sao Paulo campus. The ultrasonic signal processing is given. The results analysis enables the efficient and reliable identification of thickness and reinforcement position within the concrete slab. Construction problems were evidenced in one of experimental sections with thickness deficiencies and reinforcement in a position below projected. Furthermore, the use of a novel concrete quality indicator was correlated with the presence of transverse cracks and alkali-silica reaction within the sections.

Abstract:

Cold in-place recycling (CIR) is a pavement rehabilitation method that processes an existing hot-mix pavement, sizes it, mixes in additional asphalt cement, and lays it back down without off-site hauling and processing. The added asphalt cement is typically emulsified asphalt. A recent development in CIR technology is the use of expanded (foamed) asphalt rather than emulsified asphalt to bind the mix. This combination of CIR and expanded asphalt technologies is termed cold in-place recycled expanded asphalt mix (CIREAM). The Ministry of Transportation Ontario (MTO) constructed a CIREAM trial section on Highway 7 in July 2003. The 5-km CIREAM trial section was constructed adjacent to an 8-km section on which conventional CIR was performed. CIREAM placement resulted in a smooth, hard, uniform surface that provided an excellent platform for paving operations. The CIREAM placement progressed in a continuous and efficient manner, with 5 km placed over a 3-day period. Indirect tensile strength testing was carried out on both materials during construction. Falling weight deflectometer (FWD) testing and evaluation of pavement roughness and rutting by the use of MTO's automatic road analyzer (ARAN) were carried out. Resilient modulus testing of core samples of the CIR material and CIREAM was also carried out. The results of the FWD, ARAN, and resilient modulus tests indicated that the CIR and CIREAM pavements were performing similarly. A field review 1 year after construction showed no discernible distortion, rutting, or cracking. On the basis of short-term results, CIREAM appears to be an acceptable in-place recycling and rehabilitation strategy that provides an economical alternative to conventional CIR, reduces curing time, and extends the construction season.

Abstract:

We studied various technologies of finishing the upper layers of the concrete pavements. The analyses were made on the basis of own research on selected sections of motorway and express roads with a concrete surface in Poland. On this basis, the variability of equality and texture was determined depending on different types of structures, finishing methods and operational periods. It was found that the change of construction technology and the type of construction significantly influence the change of equality, while the technology of finishing the upper surface influences the texture. The best equality was obtained for the non-dilatation pavements with continuous reinforcement. It was shown that the texture indicator is strongly dependent on the pavement exploitation. In addition, an assessment of the impact of equality and texture on the noise level in the vehicle's cabin was carried out.

Abstract:

By the late 1980s several states, including Minnesota, began to wonder if American Association of State Highway Official (AASHO) based asphalt and concrete pavement designs were still valid, given the significant changes in traffic loads, materials and construction practices over time. This interest in validating current designs, as well as seeking improved and more efficient designs and materials, led to the creation of the Minnesota Road Research facility, known as MnROAD. Construction of the first phase of test sections at MnROAD took place from 1991 to 1994, and it was open to traffic loading commencing on July 15, 1994. Since 1994, three phases of pavement research have been, and continue to be, conducted at MnROAD. In its first 25 years of operation, an overwhelming amount of pavement research and development has been accomplished at MnROAD. The focus of this paper is to describe many of the more unique and significant findings that have improved concrete pavement technology not only in Minnesota, but throughout the U.S. and other parts of the world. The contributions are categorized into the following areas: design, materials, construction, rehabilitation, pavement monitoring and evaluation, and full-scale testing. In each of the areas, the significant contributions are described and relevant references are cited. The positive contributions of MnROAD toward concrete pavement knowledge and technology have been recognized, and as a result, the MnROAD facility will continue to operate successfully into the future under the National Road Research Alliance (NRRA).

Abstract:

Because of the heating limitation of old pavement and the restriction of climate, the quality of hot in-place recycled pavement was different to control. The warm m,ix asphalt technology was introduced to improve the heterogeneity and compactness of the hot in-place recycled pavement and decrease its construction temperature. The compaction characteristics of warm in-place recycled asphalt mixture were analyzed and its molding temperature was determined through the Marshall test. The pavement performance of warm in-place recycled asphalt mixture was analyzed whose results indicated that the introduction of warm mix asphalt technology was able to improve the compactness, the high temperature stability and water stability of hot in-place recycled asphalt mixture and reduce the influence of environment over its construction quality. A warm in-place recycled engineering of Shian expressway was introduced to verify the feasibility of warm in-place recycling technology which demonstrated that the warm in-place recycling technology was able to improve the heterogeneity and compaction quality of the recycled pavement and weaken the environmental pollution.

Abstract:

Intelligent compaction (IC) is an emerging technology with rollers equipped with global navigation satellite system (GNSS), an accelerometer-based measurement system, and an onboard color-coded display for real-time monitoring and compaction control. Paver-mounted thermal profiling (PMTP) is used to monitor asphalt surface temperatures behind a paver with a thermal scanner, and to track paver speeds, stops, and stop durations. Leveraging both IC and PMTP technologies allows for paving and compaction controls in real time, and for executing appropriate adjustments as needed. A case study is used to demonstrate the advantage of using both IC and PMTP over conventional operations. Postconstruction asphalt coring and tests, as well as pavement profile surveys were conducted to provide asphalt density data and pavement smoothness acceptance data for comparison and correlation analysis with IC and PMTP data. The data from 2 days of operations, one without the Material Transfer Vehicle (MTV) and another with the MTV, were analyzed and compared to illustrate the benefits of using IC, PMTP, and MTV for producing quality pavement products. Durability and smoothness are two key construction qualities for agencies and users of hot mix asphalt (HMA) pavements. These two factors also affect the long-term structural and functional pavement performance.

Abstract:

An experimental facility has been constructed near the campus of Auburn University in Alabama for the purpose of conducting research to extend the lives of flexible pavements. Experimental sections on the 2.8-km Pavement Test Track are cooperatively funded by external sponsors, most commonly, state departments of transportation, with operation and research managed by the National Center for Asphalt Technology (NCAT). Forty-six different flexible pavements were installed at the facility, each at a length of 61 m. Materials and methods unique to the section sponsors were imported during construction to maximize the applicability of the results. A design lifetime of truck traffic is now being applied over a 2-year period, with field performance documented weekly. Sponsors typically compare the performance of two or more sections constructed with different materials or by different methods to obtain information that can be used to build future pavements with the greatest amount of rut resistance. In addition to assessing alternatives for sponsors, NCAT is responsible for guiding the overall effort in a direction that will address policy issues for the highway industry as a whole. Specifically, laboratory methods that have the potential to predict rutting when they are used before and during construction are being compared with field performance for every experimental mix so that the most suitable method(s) can be recommended. Results from loaded wheel testing are presented to encompass the empirical approach, while results from shear and creep testing facilitate mechanistic analyses. The success of each method will ultimately be measured by comparing the performance in the laboratory with the performance on the experimental roadway.

Abstract:

Steel bridge has the advantages of large span capacity, fast installation speed, easy transportation, easy repair and replacement, and has been widely used in practical engineering. The bridge deck pavement of the steel bridge is a crucial link in the whole building and cannot be ignored. For the long span steel bridge, the bridge deck generally has the phenomenon of fatigue cracking, and the service life is difficult to reach the expected life. Laying a multi-layered protective layer structure on the orthotropic steel bridge deck can not only protect the steel bridge deck, but also increase the service life of the bridge. It also provides support and guarantee for the safety and comfort of the bridge. In addition, it effectively reduces vibration and noise caused by driving. Firstly, the advantages and disadvantages of the three types of steel bridge deck pavement technology commonly used in China are discussed in this paper, the merits of different deck paving techniques are pointed out. Then, the construction technology of the lower cast type + SMA pavement structure is analyzed in combination with a steel bridge deck construction case and the quality standard of steel bridge surface construction mixture and the inspection requirement of SMA construction quality are given in order to provide some reference for similar projects.

Abstract:

High-type roads in Tanzania have been predominantly of asphaltic concrete construction. This ever enlarging and ageing asphaltic road network represents increasing resource requirements on the road agency in the form of maintenance. Limited resources coupled with the ever sky-rocketing costs of petroleum products and the competing demands of social economic developments, presupposes the need to look for alternative road construction technology that is more cost-effective and resource optimising. Experience gained from developed and some developing countries where concrete pavements have been widely used suggests the potential of this type of pavement in many developingcountries. This paper discusses the technical aspects of design and construction- and maintenance-related aspects of concrete pavements. The discussion extends further to highlight issues pertaining to the performance of concrete pavements and strategies for promoting the use of concrete pavements in Tanzania. Conclusions and recommendationsare made with suggestions on how to start implementing the proposed strategies.

Abstract:

This paper focused on the optimization of the C40 fly ash concrete pavement, which was considered as a measure to accelerate the consumption of industrial solid wastes such as fly ash, committing to the goal of zero waste. By comparing with three groups of ordinary mix proportion, the performances (e.g., mechanical properties, durability, and brittle property) of the optimized mix proportion were evaluated via multiple mechanical and physical tests. Their air voids’ structure was characterized by the BJH method (a method to calculate pore size described by Barrett, Joyner, and Halenda), and the results were combined with the road performances of concrete to analyze the formation mechanism of high durability of optimized fly ash pavement concrete. As for the experimental results for the optimized, its 28 d compressive strength peaked at 50.8 MPa together with corresponding 28 d flexural strength at 8.2 MPa, which indicated a favorable mechanical performance for wide application in pavement construction. Except for the mechanical properties, the better durability indicators obtained after optimization also provided a more compact pore structure for the optimized. The raw materials and construction technology of the two kinds of pavements were compared. Promoting the use of optimized fly ash pavement concrete can break the situation of the asphalt pavement monopolizing heavy-haul highway and greatly reduce the industrial wastes which can be used as raw materials in the production of cement, such as blast furnace slag and fly ash. It was proved that the optimized fly ash concrete pavement can be used to replace the asphalt pavement under the premise of achieving the same working performances.
