WATER PERMEABLE SIDEWALK ASPHALT MIXTURE

摘要

The water permeable asphalt blending agent for pavement 2.5-5.5% in the mixture of the asphalt for pavement 72-94%, acryl series modified butadien polymer (liquid type at room temperatur) 5-26%, and ammonium chloride 1-2% was mixed with crushed stone granules 94.5-97.5% to manufacture water permeable asphalt.
