Pervious Concrete: Potential Advantages in Regions with High Precipitation

In regions with high precipitation, the accumulation of surface runoffs in public passages where the restriction of traffic load of vehicles and people would potentially cause lots of problems and the necessity of using pervious concrete becomes clear. The structure of this type of concretes is almost the same as the regular concretes; only due to its significant porosity, the surface runoffs can cross through the concrete body. In this forum, while describing the methods of making pervious concretes and their implementation and physical properties, some other advantages of using these concretes especially in regions which are receiving heavy load of rain are addressed; so that, given the performed investigations, in many cases, constructing roads with pervious concretes seems to be more cost effective than using the traditional methods such as asphalt or impervious pavements.
