Abstract:This paper proposes and analyzes a pavement fatigue life prediction method for asphalt and cement concrete pavements. A theoretical frequency domain analysis involving pavement fatigue life was conducted. By using the vehicle-road coupled vibration system model, the random vibration between a vehicle and road caused by road roughness was analyzed. In this paper, it is proposed that the random power spectral density of the vehicle-road coupled vibration is a useful tool to predict the fatigue life of pavements,… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
