The green growth is one of critical issues to mitigate greenhouse gas emissions and reduce fossil fuel to promote sustainable economic development in the world. In order to build environmentally sustainable asphalt pavements, a wax-based WMA additive, called low energy and low carbon-dioxide asphalt pavement (LEADCAP), was developed to reduce mixing and paving temperatures applied in asphalt paving process in Korea. The main objectives of this study are to build WMA field trial sections using LEADCAP additive along with the control HMA section and to measure the emissions and fuel consumption in the plant. Also, rutting resistance of WMA mixture using LEADCAP additive is evaluated in the laboratory. Based on the limited laboratory and field experiences, the energy savings and the air quality improvements by WMA mixture were observed and rutting resistance of WMA mixture is superior to that of HMA mixture.
