Abstract:

Roughness is widely regarded as the most important measure of pavement performance because it is the measure most evident to the traveling public. It greatly affects ride quality, safety, and vehicle operating costs. Therefore, understanding how and why roughness occurs in pavements is of major concern to highway agencies. To this end, the Long Term Pavement Performance (LTPP) program recently completed a study to investigate the changes in roughness of flexible pavements over time and their relationship to design factors, subgrade conditions, and climatic conditions. The results of this study were published in Report No. FHWA-RD-97-147, "Investigation of Development of Pavement Roughness". This document reviews that report.
