Laboratory performance of porous asphalt mixtures containing Ethylene Propylene Diene Monomer - EPDM

Abstract

Porous asphalt pavements are environmentally friendly permeable road pavements. There is a need to improve the strength performance of porous asphalt mixtures. Waste Ethylene Propylene Diene Monomer (EPDM) rubber modification of porous asphalt mixtures is investigated in this study. The mixture was initially designed for the selected mix aggregate gradation. Waste EPDM rubber scraps were replaced with filler materials at the rate of 2 % and 4 % of the total aggregate weight. Performance tests were conducted on test specimens. The EPDM rubber scraps improved the elasticity and strength properties of PA mixtures.
