ON EXPEDIENCY OF ACTIVATION OF THE MINERAL PART OF ASPHALT-CONCRETE MIXTURE IN ORDER TO DETERMINE THE OPTIMAL POLYMER CONCENTRATION
It is shown that from the existing ways of ensuring ability of an asphalt concrete covering to resist to a shearing and fatigue breakdown activation of a surface of a mineral part of asphalt concrete DST-30-01 block copolymer is. It is established that at percentage by weight on the surface of mineral powder as a part of asphalt concrete mix of 0,7% from weight divinylstyrene on dependence compressing strength at 50°C is observed obviously expressed extremum (maximum).
