Abstract
Warm Mix Asphalt (WMA) is a type of asphalt mixture that uses technology based on green technology. It is produced with a mixing and compaction temperature lower (200C to 400C) than the mixing temperature for hot mix asphalt (Hot Mix Asphalt, HMA). To improve the bond between aggregate and asphalt, Rediset LQ1106 was added. The durability of asphalt concrete mixtures influences a road^s performance and service life. The study aimed to obtain the property value of Marshall asphalt concrete mixture with the variation of immersion time at a fixed temperature of 600C and the durability of warm asphalt concrete mixture AC-WC. Marshall immersion modification was carried out in the time of 6, 12, 18, 24, 30, 36, 42, 48 hours with an optimum asphalt content of 6.25% and Rediset LQ1106 2.25% against the Optimum Asphalt Content-Marshall test method based on SNI 06-2489-1991. The parameters used to see the durability level of the results of the study showed that the Marshall characteristic values which included VMA, VFB, VIM, Stability, Flow and MQ were 18%- 75.7%- 4.4%- 1116kg- 3.5 mm, and 318.9kg/mm, respectively. The longer the asphalt mixture is submerged in water, the more the durability of the AC-WC warm asphalt concrete mixture decreases, both in terms of the Residual Strength Index (IKS) and the Durability Index value. The IKS value required by Bina Marga, (2018) is 90%. The Durability Index of test specimens that have decreased in strength is quite large along with the increase in immersion time compared to normal test pieces, so that test specimens that have undergone aging are considered not sufficiently resistant to damage caused by the influence of water
