| Abstract: | The mix designs for base course materials of porousconcrete are put forward in this paper. Tests show that the concrete has higher strength and permeability; besides, it can be got from tests and mechanism analyses that the concrete has such road performances as less temperature, small shrinkage and good frost resistance etc. |
| |
| Keywords: | porous concrete mixture ratio strength percentage of void permeability coefficient shrinkage frost resistance |
