Abstract:Roughness is widely regarded as the most important measure of pavement performance. To better understand how and why roughness occurs in pavements, Long Term Pavement Performance (LTPP) program recently completed a study entitled, "Investigation of Development of Pavement Roughness". A component of the study investigated the changes in three types -- Jointed Plain Concrete Pavement, Jointed Reinforced Concrete Pavement, and Continuously Reinforced Concrete Pavement -- of Portland Cement Concrete (PCC) pavement roughness over time and its relationship to design factors, subgrade conditions, and climatic conditions.
