In pavement structures that are often submerged bywater, the damage to pavement is often caused by the loss of bondsor adhesions between the aggregate and asphalt, the type ofdamage that occurs due to the loss of adhesion between theaggregate and asphalt is the exfoliation of asphalt granules sothat the road is cracked and corrugated. To reduce the release ofaggregate granules and improve the bond between aggregates andasphalt can be made with the addition of anti-exfoliating additivesor antistripping agent additives. This study aims to analyze theperformance of wear-coated concrete asphalt mixture (ACWC)with the addition of antistripping additives. Antistripping agentsused in this study were Zycotherm, Morlife and Adhebit withvariations of 0.1% addition, 0.3% and 0.5% of the weight ofasphalt mixture. The results of this study showed that ACWCmixture with the addition of Zycotherm additives resulted inoptimum Marshall stability and increased durability at 0.5% andAdhebit additives at 0.3% levels, while in Morlife additivesalthough at 0.3% levels were able to show optimum marshallanalysis in terms of increased durability did not show expectedperformance.
