Abstract
Pervious concrete is a type of lightweight concrete that is porous, obtained by detaching sand from the normal concrete mix, therefore it really known as a no-fine concrete. The advantage of this type of concrete are lower density, less cost due to lower cement content and no use of fine aggregate. Pavements porous concrete is a noble structure design in the urban management development generally enabling water to be permeated within its structure. It has also capable in the same time to cater dynamic loading. Developing pavement materials by using rubber aggregate is an effective approach to massively utilize waste tires. Due to the negative effects that derive from large impervious surfaces in urban areas, pervious concrete has been developed, and has become an environmentally friendly pavement material. As a porous and permeable material, pervious concrete presents an overwhelming advantage in solving urban problems, such as flooding, groundwater decline, urban heat island phenomena, etc. Waste crumb rubber has been verified as a feasible modifier for pavement material. Permeability, compressive strength, workability, are tested. The results indicate that the addition of rubber slightly decreases strength and permeability, but significantly enhances ductility and freeze- thaw resistance. Fine crumb rubber with a suitable incorporation level could remarkably improve the ductility and freeze–thaw resistance of pervious concrete without sacrificing excessively strength and permeability.
