  • POLYMER MODIFIED ASPHALT

    AAT provides a superior solution for the production of polymer modified asphalt. Our on-site blending operations provide hot-mix contractors the flexibility to produce multiple grades of binder, including most performance grades (PG), from the same base asphalt cement (AC) source. This enables you to run jobs requiring different asphalt grades using the same base AC and one storage tank.

    Works With Any HMA Plant

    Our on-site blending works with any hot-mix plant and will not interfere with normal operations. AAT’s high shear blenders mix polymer with your base AC to produce high quality, consistent modified asphalt. The modified binder is then pumped into our heated and agitated storage tanks where it is ready for use. Average production rates are between 10 and 15 tons of modified binder per hour. The blender/storage combination supports up to 4,500 tons of hot mix per shift.

    Point of Use Sampling and Testing

    AAT’s skilled technicians perform on-site quality control tests. Samples are also sent to our AASHTO accredited laboratory for performance grade certification.
