REHABILITATION TECHNIQUES FOR STRIPPED ASPHALT PAVEMENTS IN MONTANA

Asphalt stripping is a fairly common form of distress for pavements in Montana. Currently, the standard technique for rehabilitating these pavements involves the costly removal of most or all of the stripped material, prior to the placement of an overlay. The goal of this research is to determine whether the stripped material can remain in-place, serving as a structural layer within the rehabilitated pavement. This study has involved the construction of five test sites throughout Montana, which have been incorporated into larger overlay projects. At each of these sites, stripped material was removed and replaced from a control section, and stripped material was left in-place on a test section, prior to the placement of an overlay. Only the driving course (chip seal or an open graded friction course) was removed from the test sections. This report provides background information on the test sites and it describes the methods (visual, nondestructive testing, and destructive testing) that are being used to monitor the performance of experimental pavement sections. Performance results are provided for up to four years of service.
