摘要

Asphalt Concrete mixture of polymer modification are used to reduce the damage early and increasing the durability of pavement to various damage such as permanent deformation, fatigue during this process the polymer asphalt mixing using Hot Mix Asphalt / HMA. In accordance with the name and nature of hot mix asphalt, require high enough heating temperature on the Asphalt Mixing Plant (AMP), and also requires a high temperature compaction. As a result, it takes quite a lot of fuel so produced a large exhaust emissions. Emissions generated during the mixing process and compaction of HMA is a challenge for the environment. Some countries have developed a method of asphalt mixture to overcome this by using Warm Mix Asphalt technology. Warm Mix Asphalt is the technology of mixing and compaction temperatures of asphalt mixtures using mixing and compaction temperatures lower than Hot Mix Asphalt. Decreasing the mixing and compaction temperatures by adding additives to the asphalt mixture. Types of additives that have been widely used and developed for Warm Mix Asphalt them is the use of synthetic zeolites with various trademarks such as Aspha-min (R), Sasobit~((R)) dan Advera~((R)). In this paper the synthetic zeolite will be replaced by natural zeolite as an additive to be mixed with a mixture of Polymer Modified Asphalt Concrete. This study uses laboratory testing, using aggregate materials from Subang, West Java, Asphalt Elastomer Polymers, natural zeolite mineral mordenite sourced from Bayat, Central Java, Indonesia. Tests using a mixture Marshall Test. Marshall test results stated that the levels of natural zeolite 1% can reduce the temperature of mixing and compaction temperatures on Polymer Modified Concrete Asphalt mix 30℃, lower than the temperature of the mixture of Polymer Modified Asphalt Concrete without zeolite.
