<p>PROBLEM TO BE SOLVED: To effectively utilize an asphalt concrete by spreading a ready mixed concrete prepared by kneading a reclaimed asphalt concrete aggregate having a grain size capable of forming water-permeable interstices with Portland cement and water all over a road surface. SOLUTION: A ready-mixed concrete prepared by kneading a reclaimed aggregate obtained by pulverizing lumps of an asphalt concrete peeled from a pavement surface and then sieving the pulverized material and having 5-13 mm particle size with Portland cement and water, as necessary, a pigment is spread all over a road surface. Thereby, the asphalt concrete having a difficulty about disposal treatment can be utilized as the reclaimed aggregates and interstices among the aggregates of a paved roadbed concrete mutually communicate. As a result, water-permeating actions of water dropped to the surface on passing through the interstices, reaching the ground surface and permeation into the ground surface can be performed.</p> |
