For safety reason, porous asphalt has been developed in many countries to avoid aquaplaning, so that the road surface
could provide sufficient skid resistance for the vehicles to avoid accidents. This paper evaluates the use of aggregate
gradations applied in several countries such as; United Kingdom, Switzerland, Japan and Indonesia for porous asphalt
production using local materials available around Surakarta. The experimental method was applied for this research
including Marshall stability and flow to determine the optimum bitumen content, followed by the cantabrian and unconfined
compressive strength at the optimum bitumen content. The results show that Japanese gradation is the best gradation
could be applied for local materials around Surakarta, meanwhile Indonesian gradation is the worst in Marshall
stability and resistance to segregation.
