Roughness progression of asphalt overlays in the C-shrp's LTPP study
Abstract
The Canadian Long Term Pavement Performance (C-LTPP) study, initiated in 1989, involves 65 sections in the 24 provincial sites that received various thicknesses of asphalt overlays. This paper describes the impacts of these overlays on pavement roughness progression under comparative traffic loading, climate, and subgrade soil conditions. Progression of roughness for thin overlays (30-60 mm) is significantly higher on a national basis than for …
