Abstract

The impact of high rainfall and uncontrolled traffic loads, it is necessary to conduct research on the use of concrete waste materials as a substitute for coarse aggregates in order to reduce the limitations of natural aggregates and wetfix-be additives with the aim of increasing performance, strength, durability, stability, and AC-WC mixed resistance. This research was conducted using variations of 0%, 40%, 80% and 100% concrete waste. Variations of additives are 0.15%, 0.25%, 0.35% and 0.45% by weight of asphalt. The value of normal asphalt content obtained was 5.35% and the optimum asphalt content of 100% concrete waste was 5.60%. Marshall characteristic values include stability, flow, density, VFA and VIM, namely the variation using 100% concrete waste and wetfix-be additives (1322,617 kg, 3,883 mm, 2,222 gr / ml, 49,731 %, 12,225 %). normal variation (998.23 kg, 3,311mm, 2.455 gr / mm, 77,519 %, 3,672 %). Based on the results of the analysis, the variation of the mixture of 100% concrete waste and the addition of 0.25% wetfix-be has good durability.
