Comparative Analysis of Physical and Mechanical Properties of Two Types of Asbestos as a Reinforcing Material for Asphalt Concrete Mixture
Abstract: This article is devoted to the comparative analysis of standard asphalt concrete type B and dispersed reinforced asphalt concrete type B with two types of asbestos and their influence on the physical and mechanical properties of asphalt concrete mixture. Reinforcement of asphalt concrete mixtures with the introduction of 1 % fibers showed a positive increase in the physical and mechanical properties of the material. The results of reinforced asphalt concrete type B with 1 % amphibole asbestos fiber, 1 % chrysotile asbestos fiber, and standard asphalt concrete type B were compared. The introduction of asbestos fibers significantly increases the compressive strength of asphalt concrete. The tensile strength of standard asphalt concrete type B at 20 °C was 3.1 MPa, reinforced with 1 % chrysotile-asbestos fibers, the values of the compressive strength at 20 °C were 5.1 MPa, and the value of the compressive strength at 20 °C of the asphalt concrete mixture type B reinforced with amphibious asbestos fiber was 4.7 MPa. The introduction of asbestos in the composition of the asphalt concrete mixture leads to a change in the heat resistance coefficient Kt = R0/R20, which varies from 3.2 to 3.6. This provides additional thermal resistance of the material.Keywords: asphalt concrete mix, asphalt concrete, chrysotile asbestos, amphibole asbestos, dispersed fibers.
