THE CORRELATION BETWEEN EXISTING METHODS FOR ASSESSING THE SKID RESISTANCE OF ASPHALT CONCRETE PAVEMENTS

Abstract

Currently, the rapid development of the automobile industry leads to an increase in traffic intensity on the roads, a sharp change in traffic flows in a short period of time results an increase in the number of road accidents. Pavement texture and skid resistance are important pavement transport-operational indicators of roads, which determines the friction between the pavement surface and vehicle tyres. Implementing optimal procedures for maintaining a sufficient texture and friction coefficient are important for minimizing road accidents. Therefore, the research discusses the measurement methodologies, correlation and resource-cost effectiveness of the mean texture depth (MTD), mean profile depth (MPD), British pendulum number (BPN) and coefficient of friction (FC) measurements on a 4R18 road in Uzbekistan.
