Warm mix asphalt with zeolite - aspha-min

Warm mix asphalt (WMA) The use of aspha-min® allows mixing and laying temperatures of asphalt to be reduced by about 30 °C. This means saving resources and leads to less wear and tear of both asphalt plants and construction devices. Moreover, reducing the temperature in asphalt reduces the thermal aging of the binder.

Research on the Mechanism of Surfactant Warm Mix

Warm mix asphalt (WMA) refers to a form of asphalt mixture with mixing and compaction temperatures 20–55 °C lower than typical hot mix asphalt (HMA) [1,2,3].The goal of WMA is to produce mixtures with substantially the same road performance and construction workability as HMA under significantly reduced production temperatures [4,5,6,7,8].Due to the decrease of production temperature, WMA ...

Effects of Surfactant Warm-Mix Additives on the ...

2020-4-25  The warm-mix asphalt technology based on WMA is expected to reduce the viscosity (high-temperature viscosity) of asphalts during construction through addition of WMA while showing an insignificant influence on the low-temperature viscosity and rutting resistance. Therefore, it is important to determine an appropriate dosage of WMA for warm-mix HVA.
