TREATING METHOD OF PERMEABLE ASPHALT SURFACE

摘要

PROBLEM TO BE SOLVED: To prevent the separation and scattering of an aggregate by adhering a resin curing even in the presence of water on the surface of permeable asphalt. SOLUTION: 0.1-1 kg/m2, which is a quantity of a degree not blocking a gap for passing water, of a resin such as a polysulfide modified resin curing even under the presence of water by a spray 2 is adhered to the surface 1 of a permeable asphalt pavement. In addition, the resin may be adhered by a roller or a brush. In addition, thin adhesion for the uniform film formation of the resin may be performed at the number of plural times. Particular bodies such as fine quartz sand for slip stop may be sprayed in the middle number of the plural times or the surface of the number of the final painted times. The separation and scattering of the aggregate can be prevented without losing the permeability of the surface 1 of the permeable asphalt pavement.
