Background

With the development of economy in China and the acceleration of urban construction pace, the negative influence of the urban ecological environment caused by the impervious pavement is increased. Water-permeable concretes have been receiving increasing attention as a road material. Water permeability concrete is researched in the 70 th century in various countries in the world, and is applied to squares, isolation belts at two sides and the center of pedestrian streets, park roads, parking lots and the like so as to increase the water and air permeable space of cities, adjust the climate of the cities and keep ecological balance, and the effect is good. Nearly 1000 million square pavements have been laid throughout japan at present, and 80% of municipal roads in germany will be made of pervious concrete. Since the 90 s in the 20 th century, the materials for pervious concrete pavements have been studied domestically, but have not been applied in large areas so far. If the strength and durability of the pervious concrete can be improved by improving methods such as optimizing construction operation means and the like, the environment-friendly pavement material is bound to be further popularized and applied.

The permeable concrete pavement is a road material with water permeability, compared with the common concrete pavement, the permeable concrete pavement has a plurality of excellent service performances of permeability, air permeability, sound absorption and noise reduction, underground water resource protection, urban heat island effect alleviation, soil ecological environment improvement and the like, can improve earth surface circulation, is beneficial to traffic safety, protects ecological environment and solves the negative influence caused by large-scale modern urban construction.
