Primary Topic: Pavement Rehabilitation Description: 4-page techncal brief that discusses the impact of different rehabilitation treatments to reduce flexible pavement roughness. Specific factors considered include overlay type, overlay thickness, and surface preparation of the existing AC surface prior to overlay. Key findings were that regardless of the roughness before overlay, the roughness after overlay fell into a narrow band, even thin overlays substantially reduced roughness, and the IRI after overlays with minimal and intensive surface preparation prior to overlay were close to each other. FHWA Publication Number: FHWA-RD-98-149 Publication Year: 1998 Document Links: PDF (file size: 0.1 mb) PDF files can be viewed with the Acrobat® Reader®
