Abstract:

The purpose of this study was to optimize the processes of wetting fillers by varying the content of such additives as a surfactant and polymer in bitumen–mineral compositions in order to achieve optimal performance. The cosine of the contact angle was used as a criterion for assessing the adhesion of the bitumen binder to the surface of crushed stone. The effect of the additives’ concentration on surface tension and adhesive efficiency in binary and ternary bitumen compositions was studied. The following chemicals were used as additives: the original product AS-1, industrial additive AMDOR-10

Abstract. The transition to the use of crushed stone-mastic asphalt concrete mixtures in the upper layers of road clothes is a global trend and leads to increased crack resistance, shear resistance, fatigue resistance, frost resistance, as well as low abrasion resistance, reduced noise and increased roughness of the coating compared with road clothes having a coating based on traditional asphalt concrete. The production of crushed stone-mastic asphalt concrete with high performance and functional characteristics depends on the quality of the stabilizing additive used. Modern specialists are co

The effect of a complex additive containing superplasticizer C-3 on the properties of heavy concrete has been investigated. The efficiency of the plasticizing action of the specified additive at the stage of preparation of the concrete mixture and subsequent molding of concrete products has been revealed. It is proved that at the stage of concrete hardening, the investigated additive promotes to the formation of a more homogeneous colloidal-crystalline structure and the formation of dense crystalline hydrate complexes of cement stone by the time of completion of concrete hardening.

Abstract:

Introduction. The high decorative properties and durability of marble determine its wide application in many areas of construction. Natural marble with fracturing is developed for the production of crushed stone of various fractions and micro calcite. The quality of the resulting commercial crushed stone is largely determined by screening operations. One of the quality characteristics is the content of pulverized and clay particles, which reduce the ability of the material to adhere to the binder. Dry screening often fails to achieve the required quality, and the use of wet screening increases
