ASTM C884/C884M-23 is a standard test method for evaluating the thermal compatibility between concrete and epoxy resin overlays. The standard specifies the bonding performance test of epoxy resin overlays and concrete substrates under repeated temperature changes in a simulated practical use environment. By simulating temperature cycles, evaluate whether the overlays will debond to determine their reliability in practical applications. This method is suitable for epoxy resin overlays of concrete pavements, bridges and other structures, providing an important reference for engineering design and construction.
