Membranes for Pavement/Shoulder Joints

摘要

This work consisted of preventing water infiltration by (1) adding a stripmembrane over the longitudinal shoulder joint before applying the overlay, or (2) sawing-and-sealing the longitudinal shoulder joint after applying the overlay. If either method proved effective, maintenance crews would be free to perform other tasks, and useful lives of overlays would be lenghtened, resulting in savings of both expenditures and lives by ensuring safer, more durable roads. In addition to membranes, several factors were considered: variations both among the membranes tested and within test sites, and methods of data collection.
