Rosphalt® SG Asphalt Additives
Rosphalt® SG is a concentrated thermoplastic polymeric asphalt additive supplied to batch or drum plants in a dry powder form. When added at twenty-four (24) pounds per finished ton of asphalt mix (in a job mix formulation design with target air voids of 1% to 1.5%). Rosphalt® SG provides a waterproofing wear-course that is highly resistant to rutting and shoving.
Common applications are new and replacement overlays on concrete, post-tension box girder, steel grid, wood, and other bridge decks that require corrosion protection and a high-performance, long-lasting wearing course. Additional applications include road areas requiring high performance, rut, and shove-resistant pavements such as high traffic intersections, entrance, and exit ramps, and toll booths.

Easy Installation: Use of standard paving equipment and one-step integral waterproofing wearing course allows for rapid installation. Providing labor savings and quicker return to service when compared to competitive technology
Rapid Return to Service: Rosphalt® overlays can be returned to service as quickly as 1 hour (when pavement cools to 140°F).
Life Cycle Costs: Based on beam fatigue test data, Rosphalt® SG mixtures have a typical life span of 3 times traditional PG 64-22 polymer modified asphalt concrete pavements. The extended service life reduces the life cycle costs when using Rosphalt® SG mixtures, creating an advantage when compared to alternate technologies.
Maintenance Free: Stored in super sacs or bags on pallets, eliminates maintenance on storage tanks, piping and secondary containment areas.
Rut & Shove Resistance: Based on independent laboratory testing, Rosphalt® SG substantially outperforms traditional PG 64-22 hot mix asphalt.
