である。[0010] The concrete pavement method of the present invention has been conceived based on such knowledge, and a pulverized asphalt / concrete mass removed from a pavement road surface is sieved to obtain a large particle size of 5%. ~ 13mm
This is a pavement method in which ready-mixed concrete mixed with recycled aggregate, Portland cement and water is spread over the road surface.
