Primary Topic: Surface and Other Considerations Description: 4-page technical brief that discusses a study to investigate the changes in roughness of rigid pavements over time and their relationship to design factors, subgrade conditions and climatic conditions. Key findings were that there was a strong relationship between roughness and faulting, JRCP pavements with a higher roughness value were associated with high precipitation, higher moisture content, thicker slabs, longer joint spacing, and higher PCC modulus values, and CRCP pavements maintain a relatively constant roughness value over time. FHWA Publication Number: FHWA-RD-98-148 Publication Year: 1998 Document Links: PDF (file size: 0.1 mb) PDF files can be viewed with the Acrobat® Reader®
