Effects of geometrically cubical shaped aggregate on the engineering properties of porous asphalt

Porous asphalt (PA) is predominantly made up of coarse aggregates. The coarse aggregate is instrumental in providing the strength and stability of the mix. The aggregate properties including shape is expected to greatly influence the performance of PA. In this study, five different proportions of ge...
