Determining the water damage resistance of nano-clay modified bitumens using the indirect tensile strength and surface free energy methods

Water infiltration into asphalt mixtures is one the serious distresses which lowers the performance of the top layer of road pavements. This problem is even worse in tropical countries which experience high temperature and heavy rainfalls. Therefore, this study aims to evaluate the effects of water...
