Research on Application of Warm Mix Asphalt Technology in

Evaluation of selected warm mix asphalt additives

ABSTRACT Warm mix asphalt (WMA) is an emerging technology that can allow asphalt to be produced and compacted at a significantly lower temperature. In the past, a number of researchers evaluated various WMA mixtures using select testing procedures in the laboratory.

Advantages of Asphalt - EAPA

The carbon footprint of asphalt roads is lower than that of alternative products. The availability of today’s reduced-temperature asphalt materials like Warm Mix Asphalt, offering lower mixing and laying temperatures, helps to minimise the energy required to produce asphalt and, as a result, reduces carbon dioxide emissions by as much as 35%.
