TSPWG M 3-270-01.08-4 Testing Protocol for Polomeric Spall Repair Materials  


This TSPWG Manual provides a set of laboratory tests, with their acceptable results, that can be used to evaluate polymeric materials for spall repair in portland cement concrete (PCC) pavements. Common polymeric repair materials include epoxies, methacrylates, and urethanes, supplied in liquid form, often with aggregate filler. The repair kits may include two liquid components, with or without aggregate, or one liquid and one dry component. This TSPWG Manual does not address materials that require heating or melting for application. Spalls in PCC pavements consist of damage that does not penetrate through the pavement surface to the underlying layers. Spalls may be up to 5 feet (ft) (1.5 meters [m]) in diameter. Typical pavement spalls require less than 1 cubic foot (0.028 cubic meter) of repair material, although larger spalls resulting from exploding munitions can occur in contingency environments. This TSPWG Manual provides information and guidance for inspecting pavement drainage systems. Various inspection and testing techniques and the effectiveness of each are described.
