Terra Prime penetrates, bonds and stabilises the sub-base layer of asphalt pavements, waterproofing it before placing the hot mix asphalt.

Extensive testing, coordinated by the University of Texas at Austin and the Texas Department of Transportation, has determined that Terra Prime outperforms all competitor products as a replacement for MC-30, a cutback asphalt that is used globally. The Environmental Protection Agency classifies cutback asphalt as a volatile organic compound, which is regulated closely by environmental agencies worldwide.

MC-30 is laden with kerosene, a toxin, whose leaching and evaporation into the ground and atmosphere have polluted the environment for years. In addition to such concerns, MC-30 poses serious health risks to those exposed to its fumes and potential flammability. The inhalation of asphalt fumes produced by petroleum solvents can cause dizziness, headaches, intoxication and vomiting. These fumes also contain known carcinogens. Research has shown that other products, mostly emulsion-based asphalt, can replace MC-30. However, none has proved to be as effective as MC-30 — that is, until Terra Prime.

Terra Prime is calculated at a rate of 0.42 to 0.6 gal/sq yd (1.92 to 2.74 L/m2) of concentrate. To apply, simply dilute 1 part product with 5 parts water in a holding tank, then evenly distribute it over the asphalt in two passes. The use of a distributor or pressurized spraying system is highly recommended in order to ensure efficient distribution.

Terra Prime is a polymer-based emulsion that requires water dilution. It is non-petroleum-based and eco-friendly, evaporating only water during the curing process and emitting no volatile organic compounds. It does not contain solvents or cause damage to roads or vehicles. It is easily applied, requiring no special equipment or handling procedures. Terra Prime is patented by the University of Texas at Austin and licensed exclusively to Terra Pave International, Inc.

Terra Prime improves highway quality and durability by waterproofing the sub-base layer of asphalt pavements. As a replacement for MC-30, it has advantages such as:

  • Cold-applied
  • Faster curing
  • Greater strength
  • No VOCs
  • Non-flammable
