摘要
Skid resistance largely results from the interactive and collective behavior of microscopic friction behavior occurring at the rubber-pavement contact interface. This paper presents a detailed three dimensional (3D) and high resolution pavement surface re-construction methodology based on the B-rep algorithm. High resolution pavement surface data is collected by a portable laser scanning device. The linear elastic model, Mooney-Rivlin model, and Yeoh model are considered to investigate the rubber material’s influence on skid resistance. The mechanism of interface friction parameters and rubber material influencing skid resistance is discussed by means of the rubber pavement interaction finite element simulation. The influence of interface friction and rubber material on pavement skid resistance is better presented by adopting 3D re-constructed pavement roughness model. Exponential decay friction mainly affects the ability of the rubber material model influencing skid resistance. Factors that influence skid resistance are in order as kinetic friction coefficient, material type, and static friction coefficient.
