Maintenance Resealing of Rigid Pavement Joints
Transverse joints in an existing concrete pavement were resealed to evaluate a number of sealers and sealing methods. Six liquids were installed, including asphalt cement, field-mixed rubber-asphalt, two premixed rubber-asphalts, polyvinyl-chloride coal-tar, and tar-modified polyurethane, as well as three preformed neoprenes. Liquid sealers were placed 2 to 2 1/2 in. deep in some joints, and restricted to 1/2 in. in others. Some joints were sandblasted to determine the effect of clean joint faces on sealer performance. Sealer performance has been evaluated over three winters and pavement cores and sealer samples taken to observe sealer condition. Thorough joint cleaning was essential for some tested materials, but had no apparent effect on others. Generally, sealers placed 1/2 in. deep did not perform as well as those placed 2 to 2 1/2 in. deep.
