УЛУЧШЕНИЕ ФИЗИКО-МЕХАНИЧЕСКИХ СВОЙСТВ БИТУМНЫХ ВЯЖУЩИХ МОДИФИЦИРОВАННЫМИ ДОБАВКАМИ

Abstract

The article considers the influence of the content of modifying additives suchas synthetic andnatural waxesonthe properties of road bitumenbinder, use dinroad construction forthe manufacture of asphalt concrete mixtures. Themo dification of bitumenbinder properties dueto various mo difyingadditives hasbeen investigated.Byu singsynthetic waxadditives inasphalt concrete, it is possible to increaseresist an ceingauge formation in hotweather and to increase crackres istanceat low temperatures. Thus, retro fitbitumenim proversextend the life of non-rigidpavements.According to the obtaine dstudies of modifiedbits, the range of temperatures forthe preparationand compaction of asphalt concrete mixtures modifiedby the considere dadditives was determined.
