Abstract

Porous asphalt is a type of pavement characterized by a porous structure that functions to reduce water ponding on the road surface. However, its large voids and uniform aggregate size result in lower stability and binder adhesion than conventional asphalt. This study aims to improve the structural performance of porous asphalt by utilizing waste materials such as discarded tire rubber, low-density polyethylene (LDPE) plastic, and gilsonite as substitutes for penetration grade 60/70 asphalt. Besides enhancing mixture quality, using waste materials also aims to reduce environmental pollution. The optimum asphalt content (OAC) was determined based on the AAPA method, using parameters such as Cantabro Loss (CL), Asphalt Flow Down (AFD), and Voids in Mix (VIM), with asphalt content variations ranging from 4.5% to 6.5%. The OAC was found to be 5.75%. Porous asphalt mixtures were then modified by substituting 25% of the asphalt weight with three waste composition variations: 5% tire rubber, 15% LDPE, and 5% gilsonite (composition 1); 10% tire rubber, 10% LDPE, and 5% gilsonite (composition 2); and 15% tire rubber, 5% LDPE, and 5% gilsonite (composition 3). Test results showed an increase in stability, with the best stability value obtained from composition one at 641.75 kg, accompanied by VIM of 18.29%, CL of 22.76%, and AFD of 0.037%. Furthermore, durability and permeability tests met the AAPA (2004) specifications, indicating that this mixture is suitable as an environmentally friendly alternative porous asphalt material.
