Warm Mix Asphalt State of the Practice University of Idaho

"Mixture Design for Warm Mix Asphalt" is a Web-based training that presents the modifications to the current Superpave volumetric design procedure, as described in AASHTO R35, that are needed to complete a WMA mixture design.

Development and Evaluation of a Warm Mix Asphalt

To reduce the asphalt mix manufacturing temperature by 30°C from the conventional temperature. To be able to use the new material both directly in mixers at a plant plant-mix and by adding to asphalt before delivery pre-mix. To avoid any large influence on mixture characteristics in the region of service temperatures. 3.

EVALUATION OF EVOTHERM FOR USE IN WARM MIX

Evotherm® technology in Warm Mix Asphalt applications including typical paving operations and environmental conditions commonly found in the United States, and to evaluate the performance of the mixes in quick traffic turn-over situations and high temperature conditions.

Influence of warm-mix asphalt technology

Warm-mix asphalt WMA technology is an emerging technology which can reduce the mixing temperature and paving temperature 20–40 °C lower than traditional hot mix asphalt HMA, reduce the emissions, such as CO 2, NO x, etc. and at the same time keep the good compaction workability Newcomb, 2005; Rubio et al., 2012.

Research | Highway Sustainability Research Center

The research project presented herein will evaluate the moisture susceptibility and low temperature cracking properties of RAP mixtures produced with WMA technologies. Plant mixtures produced with varying RAP contents and warm mix technologies will be sampled.

Performance evaluation of plant-produced warm mix

Warm-mix asphalt WMA is the generic term used to refer to a group of technologies that are used to produce asphalt pavement mixtures at temperatures lower than those of traditional hot-mix...

Research examines mix design practices for warm mix

As most everyone working with asphalt knows, warm mix asphalt WMA is a group of processes that allow a reduction in the temperature at which an asphalt mix is produced and placed. A temperature reduction of 50¿F is fairly typical, with reductions up to 100¿F documented.

Performance evaluation of warm mix asphalt

The study compares warm-mix asphalt concrete WMA and a traditional hot mix asphalt concrete HMA, evaluating permanent deformation, fatigue, stiffness modulus, and water sensitivity.
