Abstract
Road construction requires a large amount of aggregate which will cause environmental problems due to continuous exploitation of aggregate. Reuse of concrete waste used as a substitute for coarse aggregate can be one solution. In this study, concrete waste with f'c quality of 25 Mpa in terms of aggregate properties in the form of: Analysis of concrete waste filters as a substitute for coarse aggregates of 10-20 with an average of 4.53. Specific gravity and absorption with an apparent specific gravity of 2.378 and absorption of 2.807%. Abrasion obtained a value of 37.7% and aggregate adhesion to asphalt seen visually with a result of 96% has met the requirements of the General Specification of Highways 2018 (Revision 2). Marshall test results with 50% concrete waste for stability values on rough asphalt 4.6%, 5.1%, 5.6%, 6.1%, and 6.6% with values of 1181.0 kg, 1287.2 kg, 1330.5 kg, 1183.0 kg, and 1122.0 kg. The flow values result in asphalt grades of 4.6%, 5.1%, 5.6%, 6.1%, and 6.6% with values of 3.03 mm, 3.20 mm, 3.50 mm, 3.63 mm, and 3.77 mm. It can be concluded that waste concrete as a substitute for 10-20 coarse aggregate can be used for the manufacture of road pavements on AC-BC mixtures.
