COMPARISON OF WARM MIX ASPHALT AND HOT MIX

2015-2-5  Warm mix asphalt is a kind of new pavement material, of which the mixing temperature (100°C to 140°C) is between hot mix asphalt and cold mix asphalt, and the performance is close to HMA. The main mechanism of this technology is to add chemical admixtures or water into asphalt mixture during mixing process, reducing the viscosity of bitumen at lower temperature. In such a way, good workability and reasonable long‐term performance of the asphalt mixture may be achieved (4). WMA technologies involve the use of organic additives, chemical additives, water‐based foaming processes or water‐containing foaming processes. Among them, chemical additives generally include a combination of emulsification agents, surfactants, polymers, and additives to improve coating, mixture workability, and compaction, as well as adhesion promoters. Compared to HMA, WMA has many advantages, such as less energy consumption and less pollution during mixing and paving process, better construction environment, and higher percentage usage of recycled materials. Nevertheless there are also some disadvantages for WMA, for instance, the uncertainty of its long‐term performance and higher risk of water damage, which may necessitate more frequent maintenance and therefore heavier environmental burdens. Furthermore, the environmental impacts of upstream supply chain that are used during the asphalt mix production process, for example, various additives, have seldom been taken into account.
