Comparison of Ride Improvements for Various Rehabilitation Treatments in Western Canada

A number of performance and condition parameters influence pavement rehabilitation treatment selection. One of the key parameters in assessing various rehabilitation treatment options is the pavement ride before rehabilitation and the target smoothness after rehabilitation. Some practitioners have used a broad spectrum of profile simulation tools to determine the effect of various rehabilitation strategies on the resulting post-construction smoothness. Lacking such tools, others simply rely on anecdotal improvements based on past agency or published experiences. This research study is focused on quantifying actual ride improvements realized following the rehabilitation of British Columbia Ministry of Transportation and Infrastructure and Alberta Transportation provincial highway projects. The study was designed to address two questions: How is roadway profile affected by rehabilitation treatment type? How is the International Roughness Index affected by rehabilitation treatment type? Over 150 projects totalling over 1,200 two-lane km of roadways rehabilitated over a three-year period were included in the study. Rehabilitation treatments included Hot In-Place Recycling, Mill & Inlay, and One, Two, and Three lift Overlays. (A) For the covering abstract of this conference see ITRD record number 201402RT334E.
