GAP|Patch 531
Description
GAP-Patch 531 is a robust, hot-applied, permanent repair for potholes and other larger defects in hot-mix asphalt and Portland cement pavements. Use on Portland cement requires that the substrate be pre-treated with Maxwell Products’ GAP Primer or another approved primer. Primer is recommended for installation on HMA under normal conditions but is required when installing GAP-Patch 531 during damp and/or winter weather conditions. If necessary heat the defect with a torch so primer can dry adequately in winter conditions.
Featuring a specialized, engineered aggregate designed to deliver strength, stability, and durability, GAP-Patch 531 provides a cost-effective, enduring solution. This product can be applied in up to hot temperatures and performs optimally in cold to hot climates. (Recommend ambient temperatures of 25- to 75-degrees Fahrenheit for fast setup.) It is an ideal repair solution for potholes, voids, very wide cracks, depressions, around embedded structures (drains, manholes, gutters), deteriorating shoulders, alligatored/distressed areas, wheel ruts, and raveling pavement seams on highways, municipal streets, parking lots and airports. GAP-Patch is effective for repairs from full depth to skin patching.
