A new type of pavement material using scrap rubber, the so‐called elastic and permeable pavement material (EPPM), was proposed in this study. EPPM is a new material to overcome water permeability and brittleness, which are defects of the conventional rubber asphalt and cement concrete, respectively. Those problems could be solved by introduction of grounded scrap rubber and structural design of EPPM. Results showed that key factors affecting the compressive strength and the water permeability of EPPM were the size of grounded scrap rubber and aggregate, the amounts and property of the binder. The optimum level of binder was about 8 wt%. The compressive strength and water permeability of EPPM were 1.1 and 116 times higher than those of conventional porous cement concrete, respectively.
