Impermeable cement on a pavement prevents the land to absorb water. If water can not infiltrate into ground, it is hard to evaporate in the summer time, which will influence the humidity factor in the city area. The results indicate, the data of compressive, kevlar Fiber Reinforced UP! Portland Cement Concrete on the sidewalk bricks is not better then the high pressure Cement Concrete sidewalk bricks, but about resisting flexure, kevlar Fiber Reinforced UP/ Portland Cement Concrete on the sidewalk bricks is better then the high pressure Cement Concrete sidewalk bricks. Permeability and recycle waste rubber.
