Abstract
The porous asphalt properties are different from dense asphalt concrete. Regarding the open structure of its gradation, the porous asphalt can reduce noise level from road traffic, drains water from the road surface, and the thermal conductivity. These behaviors lead to the porous asphalt contribution on road traffic safety and environment. This paper provides a comparison study regarding a literature review based on some developed countries??? experiences in using the porous asphalt related to the road safety and environmental issues. In addition, this paper presents an artificial simulation when the porous asphalt is introduced on an urban expressway in Makassar, Indonesia in order to reduce the traffic noise on the road using ASJ RTN-2008 Model approach. The simulation result shows that the porous asphalt can reduce noise level effectively during its service life
