THE PERMEABILITY AND INDIRECT TENSILE STRENGTH CHARACTERISTICS OF POROUS ASPHALT MIXES

Porous Asphalt is a bituminous mix with very low fines content resulting in high voids ratio. It is promoted as being effective in enhancing traffic safety in rainy weather,reducing hydroplaning tendencies and having good skid resistance properties at higher speed oftraffic. The use of Porous Asphalt tends also to reduce noise and glare at night. In this researchaggregate gradation proposed by the National Asphalt Pavement Association is adopted.
