Optimizing Maintenance Activities, Third Report. Shoulder Maintenance

摘要

This report summarizes the results of a cooperative Value Engineering Study of shoulder maintenance undertaken by the State Highway Agencies of Arizona, Idaho, Iowa and West Virginia under sponsorship of the Federal Highway Administration. The study was limited to unpaved shoulders. Implementation of the recommendations in the four study States would result in a total estimated improved service value in excess of $1,000,000 annually. Specific recommendations varied among the States according to local conditions. Among the recommendations are the use of larger trucks for hauling, use of side-discharge shoulder spreaders, modifications to the standard motor grader, and spot paving of shoulders in high maintenance locations.
