SULPHURIC SLIME IS MINERAL POWDER FOR COLDLAID ASPHALT CONCRETE MADE OF CATIONIC AND EMULSIFIED POLYMER ASPHALT
The mineral powder in the composition of coldlaid asphalt polymerconcrete has been appeared to structurize oil road asphalt, increases the engagement surface between sand and crushed stone grains, decreases bitumen heat expansion and slip at transport braking, increases bitumen adhesion and mechanical properties and mineral mix and asphalt polymerconcrete density. The mineral powder forms structural continuous matrix in combination with the organic binder in asphalt polymerconcrete. It also increases density, water resistance, frost resistance of asphalt concrete in the elevated temperature area. The application analysis of processed of powder like and organic products as mineral powders has been cited. The references have revealed the fact that the efficient processed primary raw materials for producing of mineral powder are sulphur bearing materials, and first of all, sulphuric slime.
