Influence of aramid and polyolefin on the technical-operational characteristics of asphalt constructions

Abstract

This paper used research results from renowned foreign and domestic institutes in terms of influence of synthetic fibres from armide and polyoefin family on physical and mechanical characteristics of asphalt mixture, firstly in terms of chemical bonding, longevity of use and solidity. The researches show that this is a new technology which provides for formation of 3D reinforcing net in the asphalt, and which has significant effect on increased resistance to permanent deformations, fractures and increased resistance with possible decreased thickness of asphalt layer and extended longevity, which provides for important economic benefit. Comparing this asphalt component with conventional we see increased resistance to “road ruts”, sensitivity to water and permanent deformation.
