Abstract
Abstract The purpose of the study is finding out the optimal use of coarse aggregates so as to obtain porous asphalt pavements that have high water absorption (porosity) but have a balance in stability and flexibilityThe porous asphalt mixture has a double water absorption (drainage system), which is on the surface that flows out of the shoulder of the road and permeates the pores or the porous asphalt mixture cavity itself.In this research study focused on finding out the optimal use of coarse aggregates so as to obtain porous asphalt pavements that have high water absorption (porosity). From the research, it is gotten the average results between the differences in the use of coarse aggregate diameter and Marshall volumetric characteristics indicate that for the Optimum Asphalt Level values, all meet the specifications of genera that produce KAO values of 7.3 percent. From the graphical observations, it can be concluded that all volumertic calculations and asphalt characteristics using coarse aggregate diameter differences concluded that the use of coarse aggregates 2 centimeter in diameter met the specifications of porus asphalt with a mean value: VMA = 48.12 percent, VIM = 4.86 percent, STABILITY = 897 Kilogram, WEAK = 3.54 milimeter, and MQ = 260.11 Kilogram / milimeter.
