THE CORRELATION BETWEEN EXISTING METHODS FOR ASSESSING THE SKID RESISTANCE OF ASPHALT CONCRETE PAVEMENTS
Keywords:
Pavement texture; mean texture depth (MTD); mean profile depth (MPD); British pendelum number (BPT); friction coefficient (FC); skid resistance.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.
