Abstract

Roads in Indonesia often experience puddles when it rains, making roads slippery and increasing the risk of accidents. Flexible pavement with asphalt as a binding material is commonly used, but it has limitations in absorbing water. Permiability asphalt was developed as a solution to improve the porosity of the mixture by using coarse aggregate and low sand content, allowing water to seep vertically and horizontally. This technology has advantages such as improved slip resistance, noise reduction, as well as better drainage function, which reduces the risk of hydroplaning when the road is wet and helps maintain hydrological balance. coarse and fine aggregate from AMP PT. Perwita Karya Sembung Batang, as well as JAP-57 Polymer asphalt. LDPE plastic is added with levels of 2%, 4%, 6%, 10%, and 18% of KAO. Steel fibers are added to strengthen the mixture and reduce the risk of cracking, while rubber is used to improve the resistance to deformation, performance at low temperatures, and permeability of the asphalt mixture. The results showed that the addition of rubber and steel fibers to the asphalt mixture affected the VIM (Void in Mix) value, with an increase in the rate of decreasing the VIM value. Marshall's testing showed that mixtures with 0% and 2% rubber content met the specifications of Bina Marga 2018, while the 4% and 8% levels were not. Permeability tests show an increase in the content of rubber and steel fibers increasing the ability of the mixture to pass water.
