Removal of water from the pavement structure provides many benefits to reduce damage on the road. Base or sub-base is a part of pavement structure, which will infiltrate the rainfall water before enter to subgrade. The research is focused on evaluating the material properties of sub-drainage layer based on Bina Marga, The Indonesian Highway Agency, Spesification 2010. This code is providing the gradation range which can be used for evaluating the aggregate of the sub-drainage layer. A series of experimental test was performed for an A class Aggregate to evaluate their performance based on the California Bearing Ratio (CBR) and modified permeability testing. The sample used in this study were consist of eight variations of A Class Agregate. Furthermore, this variation also divided into two categories which are three variations based on Bina Marga Spesification 2010 and five variations outside of Bina Marga Specification. All of the sample will be tested and evaluated to obtain the most suitable aggregate for the sub-drainage layer, which has the highest permeability and the lowest reduction of CBR value. Based on the experimental test, it was found that the average permeability was increased as the increase size of the aggregate and decrease percentage of the filler. Moreover, the bearing ratio of the sample also increase as the size of the aggregate and percentage of filler increase.
