Rosphalt® 50LT Asphalt Additives
Rosphalt 50-LT is a patent pending concentrated thermoplastic polymeric asphalt additive supplied to batch or drum plants in a dry powder form. When added at forty five (45 lbs) pounds per ton of asphalt in a job mix formulation design with target air voids of 1% to1.5%, Rosphalt 50-LT provides a waterproofing wear- course that is highly resistant to rutting and shoving and is also Fuel Resistant. Rosphalt 50-LT is produced at temperatures consistent with traditional hot mix asphalt. Common applications are new and replacement overlays on composite, orthotropic steel, post tension box girder, steel grid, wood and other common bridge decking that require corrosion protection and a high performance, long lasting wearing course. Additional applications include enhanced road areas requiring high performance, rut and shove resistant pavements such as high traffic intersections, entrance and exit ramps, terminal turnarounds, toll booths, airports, ports & terminals and auto racetracks.
|Integrated waterproofing & wearing course||One step installation|
|Uses standard paving equipment||No special equipment required|
|Lifespan of 3.5 times asphalt||Reduced life cycle costs|
|Rapid return to service||Ideal for high traffic overhead structures|
Easy Installation: Use 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 is returned to service in as little as 1 hour (Pavement cools to 140°F (60°C)
Life Cycle Costs: Based on beam fatigue test data, Rosphalt 50 has a typical life span of 3.5 times traditional PG64-22 polymer modified asphalt concrete pavements. This 3.5 times life span reduces Rosphalt 50’s life cycle costs, creating an advantage when compared to alternate technologies.
Rut & Shove Resistance: Based on independent lab testing performed by the Asphalt Institute and Worcester Polytechnic Institute, Rosphalt 50 exhibits almost 2/3 less rutting than PG64- 22.
