PURPOSE: To embody water penetrative pavement of high strength and large dry contractibility by means of easy site contruction by mixing a water penetrative pavement composition made of Portland cement or the like with water and kneading the mixture. ;CONSTITUTION: Composition for water penetrative pavement consisting of 300-400 pts.wt. Portland cement, 1400-1600 pts.wt. No.6 or 7 dry broken stone aggregate, 0.5-5 pts.wt. mixing agent powder for water-soluble or water dispersing cement is prepared. At the time of forming 1m3 water penetrative concrete, the composition for water penetrative pavement is mixed and kneaded with water so that a water cement ratio may become 30-40%, and then, construction is executed at a required place. By the way, as for this composition for water penetrative pavement, it is desirable that the adhesion water of the dry broken stone aggregate is less than 3wt.% in regard to that of the aggregate dried at 105°C. Also, it is desirable that more than 70wt.% of the mixing agent powder consists of polymer dispersion powder.;COPYRIGHT: (C)1994,JPO&Japio
