Title: Forensic Investigation of Pavement Failures due to Moisture on Interstate Highways in Oregon
Accession Number: 01124819
Record Type: Component
Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: In the last several years a number of major interstate and smaller projects in Oregon exhibited significant pavement distress that appeared to be associated with moisture damage within months following a rehabilitation activity. The premature failures prompted the Oregon Department of Transportation (ODOT) to fund a study to investigate interstate highway projects to determine the conditions and mechanisms that led to the premature failures. This paper documents forensic investigations of five Oregon interstate highway projects. Field investigations as well as laboratory testing of cores obtained from four of the five projects are documented. Improper tack coat or failure, permeable dense-graded layers, stripping, inadequate drainage, and, possibly, inadequate compaction of dense-graded material were identified as the likely root causes of the observed rutting problems on the projects that were investigated.
