| Use of the SEAM mix modifier conserves asphalt mix plant energy consumption and is less expensive to store and transport than asphalt cement.
|
|
Cost Savings - Typically reduces asphalt cement requirement by 30% (by weight).
- Addition of SEAM to paving mix reduces mixing temperature by 10 °C. This saves energy and lowers operating costs at the hot-mix plant.
- Pellets can be stored outdoors on the ground, eliminating storage heating costs and facilitating convenient shipping via rail, truck or ship.
Upgraded quality of mixes - Facilitates production of high quality paving mixes and upgrades the performance of lower quality mixes made with a high content of rounded, natural sand.
- Improves the rutting resistance of all paving mixes, including those made with soft, waxy asphalt cements .
Diminished effects of extreme temperatures - Improves pavement resistance to cracking caused by low temperatures by allowing the use of cracking-resistant soft asphalt cements without compromising pavement rutting resistance
- Effectively protects pavement from rutting caused by heavy commercial vehicles during summer heat
Improved road life - High modulus of SEAM mixes improves pavement load-spreading, reducing the stresses and strains in the base road materials and subgrade
- SEAM significantly improves the fatigue resistance of thick asphalt pavements making them excellent candidates for the long-life "perpetual" pavement designation.

 SEAM is easy to deliver in bulk by rail or truck, or in super-sacs in a container.
