Development of a new technology for determining the tire–pavement friction parameters

Abstract

The frictional properties of road surfaces are among the most critical transport-operational characteristics, directly affecting road traffic safety. They determine the ability of vehicle tires to maintain contact with the pavement during movement, especially when accelerating, braking, or changing direction. Insufficient grip can lead to skidding, increased braking distance, and loss of vehicle control, all of which significantly raise the risk of traffic accidents. Currently, there are several methods for evaluating pavement friction, but most of them are labor-intensive, resource-demanding, and do not provide complete coverage of the road surface. Furthermore, many traditional methods rely on spot measurements, which can result in missing potentially hazardous sections.

This article proposes a new approach to assessing the frictional properties of road surfaces based on the use of advanced equipment for non-contact measurement of surface microtexture. Using profilometric data, the system analyzes pavement texture and identifies critical areas with either increased or decreased roughness.

On these selected sections, the coefficient of friction is additionally determined, which allows for a significant reduction in the total number of direct measurements without compromising the accuracy or spatial resolution of the results. The proposed technology improves the efficiency of pavement condition monitoring, optimizes diagnostic costs, and enables timely decision-making regarding road maintenance and repair.

Ultimately, this contributes to enhanced traffic safety and prolongs the service life of the pavement, supporting modern road infrastructure management strategies.
