Porous asphalt (PA) is a type of layer utilized in flexible pavements, facilitating rapid drainage of water from the road surface. Consequently, the use of porous asphalt has been demonstrated to enhance road safety by improving skid resistance in wet weather conditions, reducing the incidence of hydroplaning, and preventing the transfer of water between vehicles. Furthermore, it contributes to a reduction in noise pollution and hydroplaning. The objective of this study was to investigate the performance and surface properties of porous asphalt mixtures. To this end, polymer-modified bitumen (PMB) was produced by the addition of 7%, 7.5%, and 8% of an SBS polymer additive to pure bitumen with a penetration class of 50/70 and 70/100. Subsequently, porous asphalt specimens were prepared in accordance with the Marshall design method. The Marshall parameters of the specimens were determined, and the Cantabro test (Part Loss), indirect tensile strength (TSR) test, and macrotexture tests were also performed on these specimens. The results obtained from the porous asphalt specimens for different polymer additive ratios, bitumen class, and bitumen ratios were compared. Essentially, the paper suggests that a 7.5%-8.0% SBS additive would be appropriate to meet the criteria for porous asphalt design.
