【 摘 要 】

The development of increasingly dense traffic and weather changes greatly affect the quality of the pavement which could cause premature damage. Elastomeric polymer modified asphalt is used to reduce the early damage and increase the durability of pavement to various damage such as fatigue, cracking due to temperature changes. All this time polymer asphalt mixing is using hot mix asphalt method. According to the name the hot mixing asphalt requires heating at a certain temperature which is quite high on the Asphalt Mixing Plant (AMP), also requires a certain density. Some countries have developed asphalt mixture known as Warm Mix Asphalt by mix temperatures and compaction temperatures lower than hot asphalt mixtures using the added material. Research using experimental methods with elastomeric polymer bitumen as a binder in the warm mix asphalt with the added material of natural zeolite, thus obtained mixture quality hot asphalt mixture equivalent but processed by low mixing and compaction temperatures. Based on Marshall test asphalt polymer with zeolite content of 1.5% of natural zeolite sieve no. 400, has the highest stability values 1627,7 kg, has the residual stability value of 93,36%. The value of residual stability meet the specifications Department of Public Works of Highways, 2010, indicating that the residual stability the warm mix asphalt with 1.5% Bayat natural zeolite is high and the water resistance is very good.
