PQ's ADVERA® WMA specialty zeolite is an additive for warm mix asphalt technology. Advera® WMA is added to the existing hot mix asphalt mix design to allow asphalt concrete to be produced and placed at temperatures which are 50-70°F below conventional hot mix asphalt temperatures. PQ's Advera® WMA offers numerous benefits to agencies, asphalt plant owners and paving companies.
Agencies can benefit from reduced emissions (VOC and CO2) (up to 60% reduction), more consistent pavement densities, faster opening to traffic, and night/cool temperature paving. Asphalt plant owners are able to benefit from increased use of RAP (up to 55%), energy savings (up to 35%), additional compaction for stiff mixes, extended paving season, extended paving range (over 3 hours), increased production rates, and the ability to pave over crack sealing. Paving companies benefit from longer workability (longer hauls, less scrap), fewer emissions at the paver, density bonuses, and additional compaction for stiff mixes, cooler working conditions (50-100 degrees F. cooler) and the ability to extend the paving season.
How It Works
Advera® WMA's fine particle size and timed-release water technology maintain asphalt workability at lower manufacturing and paving temperatures.
