Abstract:In the past, numerous researchers and pavement proffesionals tried to find an analytical relationship between the road roughness and the vehicle speed which were measured on the same test sections. In HDM-4, special models were developed, in which maximum limiting speeds relative to road roughness condition were calculated. In this paper, a brief review of significant research conducted around the world that analyzed the influence of increasing road roughness, expressed through IRI, on the change of vehicle sp… Show more
