Lane-Change Effect on Road Pavement Wear

Abstract

The wear of the road pavement is a widespread problem both in the Russian Federation and abroad. This work studies factors influencing the untimely wear of road pavements. The article considers the pavement changes along the rolling lanes that increase the risk of accidents in certain circumstances: aquaplaning (loss of the tire adhesion to the road surface due to a water layer), lane-change, ice on the pavement surface, etc. The article analyzes the main causes of track formation (traffic flow, load from rolling stock, constant braking and starting of vehicles) and reconstruction of vehicles is considered in detail as the least studied factor, but making a significant contribution to the untimely pavement wear. The main types of lane-change and the places of greatest commission are determined. Experimental studies concern collection of statistical data on the traffic flow, flow composition, track depth that are necessary to assess the impact factor of vehicle lane change. The road pavement wear is revealed during the monitoring of the street and road network in Tyumen. A tendency to increased wear in places of frequent rearrangements in comparison with places of their absence or minimal number was established after comparing the rut size.
