Roughness of overlays on bridge approaches as affected by pavement milling.

12407701PDFTech ReportVHTRC 84-R39VirginiaVirginia Transportation Research CouncilGunn, R. WMcGhee, Kenneth HVirginia Highway & Transportation Research CouncilUS Transportation CollectionEvaluation was made of the effectiveness of milling old asphaltic concrete surfaces for a short distance at bridge approaches in preparation for resurfacings. The results showed that such preparatory milling is highly effective in maintaining or improving pavement ride quality in the approach area. While geometrics or other considerations might preclude its use, the milling method is recommended for consideration as a procedure for preparing bridge approach areas for the placement of overlays
