As a result of the 1997 Kyoto treaty on climate changes, many countries n the world were faced with greenhouse gas reduction targets. Warm-mix asphalt (WMA) technologies are currently of interest to road construction industry around the world. WMA technology was developed in Europe and introduced into the United States in 2002. WMA technologies can decrease the energy consumption and emissions associated with conventional hot-mix asphalt (HMA) production. Based on those benefits and increasing awareness of WMA, the Korea Institute of Construction and Technology (KICT) developed WMA technology in Korea. WMA developed by KICT used a WMA additive that was developed by Korea Kumho Petrochemical Co. LTD. To evaluate the performance of WMA developed in Korea, an experimental test program was designed to evaluate rutting and crack resistance by using thewheel track test and indirect tensile strength test as a function of mixture types. In the case of rutting resistance, WMA shows better performance than HMA at high temperature. The Indirect Tensile Strength (IDT) test results of both WMA and HMA were same.
