Increasing temperature triggered by the high levels of greenhouse gas (GHG) emissions including the CO2 generated a lot of road construction, Warm Mix Asphalt (WMA) is a technology based on environmentally friendly. <br /> <br /> Percentage Sasobit® use by 3 % while Leadcap® of 1% of the weight of the asphalt. The performance WMA mixtures were measured and compared with a mixture of HMA to see properties of bitumen and the advanced rheology, while <br /> <br /> the performance of the mixture obtained from testing Marshall, UMATTA to compare resilient modulus and to see fatigue resistance. <br /> <br /> The test results showed the addition of additives DSR Leadcap and Sasobit® can change the nature of the asphalt becomes more elastic. Mixing and compaction temperatures WMA with additives Sasobit® at a temperature of 134°C/124°C while Leadcap® 124°C/114°C, where the results showed a mixture of HMA marshall higher than WMA mix. The test results UMATTA at a temperature of 25°C and 45°C the highest value on the WMA mixture with Sasobit® (3150 Mpa). <br /> <br /> The test results showed fatigue WMA mixtures with additives Leadcap® and Sasobit® increased fatigue life. <br /> <br /> Generally the additives can improve the performance of the mixture by mixing and compaction temperatures lower than HMA
