Study on the Characteristics of Japanese Gradation Porous Asphalt Using Modified Buton Asphalt

Abstract

This study aims to determine whether Japanese graded using local materials can meet the characteristics of porous asphalt and what is thecoptimum asphaltccontent in the Japanese Graded Porous Asphaltcmixture Using Asphalt Retona Blend 55, the results of the study for Japanese graded porous asphalt mixtures using modified asphalt and existing local materials. In Jayapura, the asphaltccontent value of 5.5% met the specifications. From the parameters for the porous asphalt mixture, the optimum asphalt content value is 5.5% based on the Cantabro test with a value of 7.37%, and porosity testing of 18.093%, while the marshall characteristics are stability of 538.633 Kg, Flow of 2 mm and MQ is 272.433 Kg/mm and also permeability test is 0.466 cm/s, these values meet all specifications for porous asphalt mixtures.
