STUDY OF PHYSICAL AND MECHANICAL PROPERTIES OF FINE-GRAINED ASPHALT CONCRETE WITH DIFFERENT TYPES OF ADDITIVES

Abstract

At present, an acute question has arisen regarding the search for optimal modifying additives to improve the physical and mechanical characteristics of asphalt concrete. The current operation of roads with a non-rigid road surface, increased intensity and transported goods outside the weight standards, led to a faster destruction of asphalt concrete surfaces. Accelerating the formation of track leads to a decrease in the life of the coating and leads to an increase in the number of accidents among vehicles.

Asphalt concrete coatings and repair maps that are made of ordinary not modified asphalt concrete, under the current realities of loading, are not able to provide appropriate physical and mechanical characteristics. As a result, it became necessary to find modifying additives that can improve strength, аccelerating the formation of track leads and be economically justified.
