ANALYSIS OF PROBLEMS OCCURRING ON ASPHALT-BETONE AND CEMENT-BETONE ROADS

Abstract

In this article, a thorough comparative analysis of the technological, economic, and environmental aspects of the most commonly used materials in road surfaces Asphalt concrete and Cement concrete was carried out. The analysis pays special attention to the harsh continental climate conditions of Uzbekistan, in particular, the problem of asphalt concrete deformation during hot summer temperatures. Also, the issue of ecological load (toxic emissions, CO_2) during the production and operation of asphalt concrete was studied, and the ecological advantages of cement concrete due to its durability, high-temperature resistance, and the possibility of complete recycling were shown. The second part of the article presents the results of laboratory testing methodology and determination of compressive strength of asphalt concrete mixtures based on GOST 12801-98 standards. Research justifies the need to introduce modern foreign technologies (PMB, SMA, Whitetopping, HPC) that are suitable for the conditions of Uzbekistan.
