Abstract
Aggregates are important in the construction and improvement of roads but their numbers are limited due to deep river dredging and it is therefore necessary to find other materials that can be used instead of easily and cheaply obtained aggregates. This study, using concrete waste and the disadvantage is having a high absorption because it needs to be added an additive, namely Wetfix-Be so that the use of concrete can be applied in the field. The method used in this study is an experimental method using a laboratory scale. Tests conducted in this study are concrete waste as coarse aggregate. With variations with coarse aggregates of 40 and 60, 80 and 20, 100 and 0, and the results of comparison of Wetfix-Be material used are 0, 15%, 0.25%, 0.35%, 0.45% by weight of asphalt. The results of this study proved to be able to increase the value with an optimal Wetfix-Be of 0.25% of asphalt weight and asphalt weight of 6.3% The benefit of this research is to determine the characteristics of concrete waste by using Wetfix-Be added material on the flexible pavement in the AC-WC mixture and can reduce construction waste in Indonesia.
