The effect of aggregate’s angularity on engineering properties and performance of porous asphalt

Porous asphalt is a flexible pavement layer with high percent of interconnected air void and constructed using open-graded type of aggregate. Aggregate shape and surface texture plays a vital role in determining the engineering properties and performance of porous asphalt. Angular-shaped aggregate w...
