Asphalt Institute Technical Advisory Committee. Approved 7 December 2016. The Asphalt Institute recommends that, for unmodified asphalt binders, the laboratory mixing and compaction temperatures should be determined where the viscosity-temperature line crosses the viscosity ranges of 0.17 ± 0.02 Pa-s (mixing temperature range) and 0.28 ± 0.03 Pa-s (compaction temperature range).

May 16, 2012 · Warm-Mix Asphalt: The Asphalt that is applied at 200-250 F is called Warm Mix Asphalt. Warm-Mix Asphalt or WMA is made by addition of materials like waxes or zeolites or asphalt emulsions with asphalt- binder before mixing. Sometimes water is also used as the material to be added with asphalt-binder.

Asphalt mixing plant is a kind of equipment to mix the proportioned aggregates into the asphalt mixture under the specified temperature. And its main application is to produce asphalt, modified asphalt mixture, colored asphalt mixture and meet the requirements of highway construction, classified highway construction, urban road construction, parking lots, airport construction and port construction, etc.

Mix temperature is dependent on the grade of asphalt used in the mix. Less viscous the asphalt requires lower the temperatures, while more viscous asphalt requires higher temperatures.At the start of a mix design project, target temperatures are specified for proper mixing and compaction.
