Mar 01, 2016 In 2004, Florida Department of Transportation and FHWA report that SBS benefited the cracking resistance by reducing the rate of micro-damage accumulation [30]. Due to high viscosity and improved binder coating, polymer modified asphalt (PMA) pavements have better pavement performance under high traffic applications.

What Is High Performance/Highly Modified Asphalt? Highly Modified Asphalt (often called HiMA™ or HPG) is exactly what it says, an asphalt binder with 2-3 Xthe amount of SBS polymer used to produce grades such as PG76-22 The resulting binder contains a dense polymer network that significantly improves mixture performance

heavy polymer modified asphalt binder (5-7). The current cost of PG 82-22 asphalt binder is approximately $100/liquid metric ton more than PG 76-22 asphalt binder and $250/liquid metric ton more than unmodified PG 67-22 asphalt binder. Prior to implementation, the benefits of a PG 82-22 asphalt binder should be better quantified to justify its use.

Jan 01, 2007 In general, it seems that the results of rheological tests are not indicative of the performance of polymer modified binders. Several tests exist to identify whether modification is present, such as the IR, low temperature ductility and torsional recovery. In 1991, the ISTEA required that an increasing proportion of roads use modified asphalt.

Advantages of the DH blending method. Continuous one-pass inline blending capability. Reduced digestion time. Polymer is forced through the mill seconds after it combines with the liquid asphalt. Polymer has greater tendency to shatter when it hits the mill since it hasn’t had time to become “glue-like”. German-manufactured high shear mill.

The use of PPA to modify asphalt has grown in the past decade, as has the use of other polymer modifiers. Some estimate that anywhere from 5 to 15 percent of the asphalt pavements placed in the last five years contained PPA in the binder. This increased use has also brought about a higher level of interest and concern regarding PPA modification.
