An experiment was set up to investigate the effects of soil loosening on the drainage efficiency of a structurally unstable silty clay loam in Devon. Such soils are common to the Palaeozoic slates of South West England, and in many parts of Wales and Scotland. The dominance of the fine earth fraction these soils by silt sized particles and the associated low clay fractions ( 10-35%) gives rise to weak structures that are unsuitable f or mole drainage.

Abstract:
A triaxial apparatus was upgraded and a specimen preparation device was developed to enable monotonic and cyclic triaxial testing of low plastic reconstituted silts. The silt reconstitution technique involves consolidating silt slurry inside a cylindrical split mold, directly on the triaxial base pedestal. The slurry is carefully poured into the split mold using a flexible hose. A vertical load is then applied to slurry using a top cap and loading ram. Loading is applied in an incremental manner and the slurry is allowed to consolidate, creating a specimen firm enough to carry on with triaxial

The cyclic shear response of low-plastic Fraser River silt was investigated using constant-volume direct simple shear testing. Silt specimens, initially consolidated to stress levels at or above the preconsolidation stress, displayed cyclic mobility type strain development during cyclic loading. Liquefaction in the form of strain softening accompanied by loss of shear strength did not manifest regardless of the applied cyclic stress ratio (CSR), or the level of induced excess pore water pressure (Δu). Cyclic mobility type stress-strain behaviour was observed in spite of the initial static sh

Abstract:
Due to the modernization of the construction industry, the use of waste is an attractive trend with high potential for many researchers. The majority of the waste materials that are recycled to produce new construction materials are usually by-products obtained from a variety of several manufacturing processes, such as the aggregate washing process. Recycling these materials is of utmost importance since it could reduce the adverse environmental impacts resulting from landfilling. The concept of producing asphalt mixes with waste materials serves as a way to reduce the enormous volume of waste

Construction sites are among the most common areas to experience soil erosion and sediment transport due to the mandatory foundation tasks such as excavation and land grubbing. Thus, temporary sediment barriers are installed along the perimeter to prevent sediment transport from the site.

Abstract:
<p> Deposits of coal silt are significant because they provide archaeologists a baseline for investigating changes in pre-industrial and post-industrial landscapes in Pennsylvania. Beginning in the 1790s, miners extracted coal from seams near the surface with a pick and shovel. Over the next 120 years, coal mining evolved into a booming industry. In 1917, production peaked at over 100 million tons. By 1950, geologists discovered reserves of crude oil and natural gas, leading to the overall decline of the anthracite coal industry.

Accumulations of fine sediments in deep-ocean contourites form a sedimentary record that has been hypothesized to be directly related to bottom-current behavior. This is known as the 'sortable silt' hypothesis and states that the non-cohesive, coarse silt in the 10 to 63 µm size range within a deposit can be used as a proxy for paleocurrent velocity. Slow deposition rates on contourites (2−10 cm/kyr) make it difficult to test this hypothesis in the field and few laboratory studies have been conducted.
