ASPHALT +
Almost 500 million tons of hot mix asphalt are placed on highways throughout America every year. Asphalt covers more than 94% of all roads in the U.S. In addition to road use, asphalt is the primary choice for driveways, parking lots, racetracks, tennis courts, walking and biking trails and anywhere a smooth durable driving surface is desired. Approximately 25% of the asphalt placed on highways is modified in some way to meet specific performance criteria established by individual states.
Asphalt+ is an environmentally friendly asphalt modification product, and process. Asphalt+ is a blend of high quality recycled crumb rubber powder, sized below 1.44 mm (also known as ground tire rubber) and a semi-crystalline polyoctenamer polymer. These unique white polymer shreds are carefully blended with the crumb rubber to meet state specifications to create a stronger, longer lasting asphalt product that creates a smoother, quieter and safer road. In addition, our "Plant Process Blend System" allows producers to save as much as $2-5 per ton on finished hot mix asphalt.
Many modified asphalt products are blended using SBS (styrene butadiene styrene) at oil refineries. This method of modification adds significantly to the cost of asphalt oil because the oil refiners make the additional profit on the amendment. The Asphalt+ "Plant Blend" process allows asphalt producers to be more competitive using the Asphalt+ patented delivery system where the hot mix asphalt is produced at the plant level. The Asphalt+ blend is carefully monitored by weight and volume as it is added into the hot mix using patented measuring equipment at the asphalt plant.

ASPHALT + TECHNOLOGY
- Low initial viscosity during the initial mixing process
- Increased viscosity after polymerization to prevent drain down
- Chemical bonding of the ground tire rubber to the asphalt
- Chemical bonding of the final rubberized asphalt to the aggregate to reduce stripping
- Conversion of the thermoplastic asphalt to a thermoset polymer, which reduces rutting and cracking
BENEFITS TO THE CONTRACTOR/PRODUCER AND THE STATE
- Blended at the plant where producers control costs
- Lower entry cost over traditional "wet" blending process
- Easier, faster and more uniform mixing
- Faster paving
- Superior surface finish
- Easier to work on turns and curves
- Application at low road surface temperatures and in inclement conditions
- Reduced rutting and cracking
- Longer surface life
- Quieter driving conditions
- Shorter stopping distances in wet conditions
- Better visibility in inclement conditions
- Thermally stable to 520 degrees F
- Melting point of 129 degrees F
- LOWER COST PER FINISHED MILE
