Terra Prime™

Terra Prime™ – Prime Coat – Tack Coat – deeply penetrates, bonds and stabilizes the sub-base layer of asphalt pavement, rendering it waterproof before placing the hot mix asphalt.

Terra Prime™ forms a permanent chemical bond between the prime coat and soil base, creating high bond strength and track resistance (i.e. tire tracks). Terra Prime™ superior eco-friendly emulsions form a durable chemical bond between the layers and underlying surface. This permanent anchoring of the layers ensures improved and homogenous load transfer between various layers of the pavement, while significantly reducing the layer’s potential for tracking and potential for moisture damage.

Extensive testing, coordinated by the University of Texas at Austin and the Texas Department of Transportation (TXDoT), showed that Terra Prime™ outperforms all competitor products as a replacement for MC-30/AEP/SS1, which is a cutback asphalt that is used globally. The Environmental Protection Agency (EPA) classifies cutback asphalt as a volatile organic compound, which is regulated closely by environmental agencies worldwide.

Terra Prime™ – Replacement for MC-30, AEP, SS1 MC-30/AEP/SS1 products are 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 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 invented by the University of Texas at Austin.

Terra Prime™ is applied with a high-tech distributor at ambient temperature. Terra Prime™ is cured and dry approximately 7.5 hours after placement. It has great surface strength and is ready for a chip seal, overlay or temporary traffic.
