The contents of this web site are to promote the understanding of warm-mix asphalt during its research and development phase in the United States. This web site cannot be used to promote or single out any one specific asphalt technology.

Test FrameworksThe Warm-Mix Asphalt Technical Working Group has devised test frameworks to help researchers obtain data in a uniform format so that analysis can be done by using data from a multitude of projects. There is one framework for material properties and another for emissions and energy reductions.

Products and ProcessesThese products and processes are listed for information only. The WMA Technical Working Group does not endorse any particular proprietary product or technology. These applications should be considered as experimental.
