## Abstract
Abstract Enrekang Regency, South Sulawesi Province, is an area that has a source of material in the form of river aggregate which was classified as igneous rock in Mata Allo River. However, the use of river stone so far has only been limited as to building materials and has not been used as coarse aggregate in asphalt mixtures. The use of river stone which had been underutilized is also based on the fact that there is no research on this aggregate. This study aims to determine the feasibility of Mata Allo River aggregate that can be used as coarse aggregate in the asphalt concrete binder course (AC-BC) mixture against the Marshall test. This research was conducted by testing the characteristics of coarse aggregate based on the standards of Highways, Indonesia. The composition of the AC-BC mixture as a result of aggregate gradation were 50.00% of coarse aggregate, 45.15% of fine aggregate and 5.85% of filler, respectively. AC-BC mixture were produced using petroleum bitumen of 60/70 grade penetration at variations in asphalt content of 4.0%, 4.5%, 5.0%, 5.5%, and 6.0%. Based on the results of the study, the Mata Allo River Aggregate which is classified as igneous rock is suitable for use as road material with flexible pavement construction for the AC-BC mixture resulting from laboratory testing, where the Marshall characteristic test results for the mixture meet the specifications of Bina Marga, Indonesia.
