Durability of Asphalt Concrete (ACWC) Mixed with Antistripping Additive

In pavement structures that are often submerged by water, the damage to pavement is often caused by the loss of bonds or adhesions between the aggregate and asphalt, the type of damage that occurs due to the loss of adhesion between the aggregate and asphalt is the exfoliation of asphalt granules so that the road is cracked and corrugated. To reduce the release of aggregate granules and improve the bond between aggregates and asphalt can be made with the addition of anti-exfoliating additives or antistripping agent additives. This study aims to analyze the performance of wear-coated concrete asphalt mixture (ACWC) with the addition of antistripping additives. Antistripping agents used in this study were Zycotherm, Morlife and Adhebit with variations of 0.1% addition, 0.3% and 0.5% of the weight of asphalt mixture. The results of this study showed that ACWC mixture with the addition of Zycotherm additives resulted in optimum Marshall stability and increased durability at 0.5% and Adhebit additives at 0.3% levels, while in Morlife additives although at 0.3% levels were able to show optimum marshall analysis in terms of increased durability did not show expected performance.
