Abstract

Asphalt concrete is a type of road pavement that consists of coarse aggregate, medium aggregate, fine aggregate, asphalt, and filler. This research utilizes red brick waste from the demolition remains of unused construction building as filler with a maximum grain size of 0.074 mm. The purpose of this research is to discover the effect of red brick waste as filler towards asphalt concrete density and Marshall test parameter result. The method used in this research is an experimental study of AC-WC asphalt concrete using filler made of red bricks. Based on density test and Marshall test with immersion time between 30 minutes to 24 hours, the result shows that density value experiences an increase from 2.344 to 2.441, while VMA value experiences a decrease from 17.692 to 17.369, VFA value experiences an increase from 77.567 to 79.330, VIM value experiences a decrease from 3.652 to 3.576, stability value experiences a decrease from 1093.220 to 1002.763, flow value experiences a decrease from 4.467 to 3.800 and Marshall quotient experiences an increase from 244.720 to 265.863. Based on the test results, it can be concluded that the value obtained is still above the AC-WC asphalt specification minimum value. Therefore, red bricks can be used as filler for AC-WC asphalt concrete mixture.
