  • Abstract:
    Warm Mix Asphalt (WMA) technology, recently developed in Europe, is gaining strong interest in the US. By ; lowering the viscosity of asphalt binder and/or increasing the workability of mixture using minimal heat, WMA ; technology allows the mixing, transporting, and paving process at significantly lower temperature. Using this ; new technology, asphalt mix can be produced as much as 100ºF lower than traditional hot mix asphalt (HMA). ; Several benefits of lower mixing and compaction temperature include: less emission, savings in energy cost, ; longer construction season, less odor, and construction during non-peak periods. Despite the apparent benefits, ; some researchers are concerned about the long-term performance of this new mixture. In last few years, dozens ; of field test sections have been constructed thorough out the USA using different WMA technologies. It is too ; early to report the performance; but so far, no negative performance has been reported in the literature. In the ; last few years, several large national and state level research projects have been initiated to evaluate, validate, ; and implement this new technology. ; This report documents the results of a comprehensive review of worldwide information dealing with the ; following issues as related to warm mix asphalt: Current state of the art/practice of WMA; cost and benefits of ; WMA technology; plant modifications to accommodate WMA; mixture design; durability and performance; ; performance related testing; quality control; specifications; and construction guidelines.
