THE EFFECT OF TEMPERATURE-REDUCING ADDITIVES BASED ON SYNTHETIC WAXES ON THE PROPERTIES OF BITUMEN

Obtaining warm asphalt concrete mixes is an urgent task in the road industry, as it allows solving environmental, technological and economic problems of preparing laying concrete. One such technologies production using organic additives based on synthetic waxes, which until recently were presented market exclusively with imported products. In current political situation, relevance development implementation domestic analogues wax temperature-lowering becomes important task. The article studies effect waxes physico-chemical properties bitumen binder penetration, softening temperature, extensibility, fragility temperature by Fraas, adhesion to crushed stone. indicators comparative analysis binders modified complex additive Viskodor PV-2 Licomont BS-100 Sasobit are given. It was revealed that new has advantages over additives: lower brittleness binder, increase mineral materials a smaller decrease penetration. Rational concentrations use have been established.
