Therefore, energy saving and carbon reduction, sustainable use, and environmental consciousness becomes the main theme for discussion. The present study investigates on three aspects. First, estimate the degree of warm mix asphalt and hot mix asphalt during the procedure. Second, estimate at carbon reduce emissions while processing asphalt pavement. Finally,the asphalt concrete effectiveness of the test. The processing of hot mix asphalt usually hazy with smoke and result in greenhouse effect, moreover, it will influence the health of worker as well as climate serious negative effect. Hence, this research assumes that decreasing the temperature of during operation can avoid negative effects. The present study use an additive to manufacture the warm mix asphalt in order to decrease the temperature, moreover, this research aim at the additive character of warm mix asphalt . This study with the mix design practices, this is, 0%, 20%, 40 and 60 % RAP to compare the HMA and WMA carbon emissions, cost differences and effectiveness of the test results. The result of this experiment confirms that decreasing asphalt mix temperature can reduce carbon emission. Nevertheless, knowing well characteristics of blending and evaluating condition risk before application are the most important aspec.
