Abstract

The decisive influence on the corrosion resistance of asphalt concrete, and, consequently, on its durability is influenced by the presence of structural bonds at the interface between phases "crushed stone - binder". The weakening of these bonds leads to formation of various defects in roadway - cracks, potholes, etc. The article examines influence of mineral fillers made of non-carbonate raw materials on the durability of asphalt concrete. Analysis of group composition of bitumen made it possible to establish a mechanism for slowing down the aging rate of an organic binder when using porous mineral fillers made of natural zeolites and brown coals. It was found that asphalt concrete with natural zeolite and brown coal in their composition have low dependence of deformative properties on ambient temperature compared to asphalt concrete with traditional limestone mineral filler.
