The warm mix of foam asphalt begins from 2005 in China, by researching the international warm mix technology, we put the research emphasis on the warm mix based on surface activity platform and the one with organic additives. Compared with other asphalt mixing technologies, the warm mix asphalt has more advantages:
1. Lower temperature operation
Greatly reduce the hot mix temperature (30-50°). It minimizes the mixing and paving temperature and the smoke and odour emissions are greatly improved. In additional, it creates friendly working conditions for the asphalt workers.
2. Economy benefit
It can reduce 30% fuel consumption and increase the proportion of recycled asphalt added (if have).
3. Environmental protection
With WMA the emission of pollutant smoke is greatly improved. Including CO / CO2, SO2/NOX etc. Lower mixing and paving temperature will result in reduced greenhouse gas emissions.
4. Good mixture performance
Foamed bitumen warm mix asphalt system/foaming system is a mature technology. According to the many times of mixture performance test both in lab and road, the all key parameters are proved of normal even higher than normal process mixture, No matter SBS bitumen or normal AC13/AC20. With this kind device user can reduce the aging of asphalt pavement, and improve performance on mixture.
For assure the stable and service life of this device, we select the most famous brand to supply the key components. PRIMACH always keep pace with the international advanced technology.
The warm mix asphalt is advanced, because it's the demands of“energy conservation and emission reduction”and“green development”.
