Abstract

Pavement construction requires aggregate which is non renewable material. Concrete waste such as from cubic test might be recyded. This study investigated marshall characteristic of Asphalt concretebinder course (AC-BC) which used of concrete waste as coarse aggregate substitute. Concrete waste was mixed with fresh aggregate at ratio of 100:0, 75:25, 50:50, 25:75 and 0:100 Asphalt contentvariation are 5%, 5.5%, 6%, 6.5% and 7%. The optimum aggregate contents for each variation are 6.08%, 5.83%, 5.87%, 5.10%, 5.55% respectively. The result show that all variation fulfilled the specification The 75:25 variation is recommended as mixture ratio with high stability value of 1445 Kg, Flow 3.40 mm, VMA 15.30%, VFA 77.50%, VIM 3.40%, MQ 440 Kg/mm and also asphalt content is affordable with 5.87% of optimum asphalt content.Keywords: AC-BC, Concrete Waste, Coarse Agregate
