Florence, Texas – Terra Prime
Terra Prime, the world’s most eco-friendly prime coat, applied on a TxDOT test section on highway SH-195 in Florence, TX. Terra Primeis a unique, water-based and environmentally friendly prime coat tested by the Texas Department of Transportation (TxDOT) for applying on Texas roads. It is very easy to use, requiring no special equipment or instructions. Terra Prime outperforms the most widely used alternatives, such as MC-30 and AEP — both of which emit volatile organic compounds (VOCs) and are at least partially prohibited for use in Ozone Nonattainment Areas, like crowded cities and metropolitan areas. After extensive testing coordinated by the University of Texas at Austin and TxDOT, it is clear that Terra Prime outperforms all known competitor products as a replacement for MC-30, an asphalt primer that is used worldwide. MC-30 is classified as a cutback asphalt that contains up to 50% kerosene, which is environmentally toxic. The Environmental Protection Agency classifies cutback asphalt as a VOC, which is closely regulated by environmental agencies worldwide. Terra Prime has the following advantages over the competition for MC-30 replacement: Environmentally Friendly Safe to Handle More Economical Greater Strength Less Permeable Faster Curing Time Cold-applied — No Heating Required Easy to Apply — No Special Equipment Required Terra Prime is very promising for the construction of better and greener roads....

Terra Fog™ application on Collingsworth County Rest Areas Collingsworth County Rest Area Pavement Repair Background On Tuesday, July 2, 2013, ICA performed pavement preventive maintenance on Collingsworth County Rest Areas with Terra Fog from Terra Pave International. Terra Fog is a special polymer. Other materials used include limestone base screenings (dust to 3/8”) and masonry sand. Facility Collingsworth County Rest Area is located on US 83 approximately 37 miles North of Childress Texas. It includes approximately 1450 feet of roads from 21’‐35’ wide. There were a number of previous repairs that appear to be hot mix asphalt pavement probably 10 years old or older. Some of the old repairs are substantially alligator cracked. Other Repair and Fog Seal Areas Procedures Alligator cracked areas were blown out and the area cleaned of debris. A diluted mixture of 2 parts water and 1 part. TF was sprayed on area . Cracks were filled with limestone base screenings and the area was squeegeed to coat the aggregate with TF and to fill the cracks. Larger aggregate was removed. The same procedure was used on other area, but the aggregate used was a washed masonry sand. The finer sand was easier to squeegee into the cracks and to make smooth, but may take longer to cure since the aggregate does not absorb water like the base material. The whole area was then sprayed with a mixture of 1 part water to 2 parts TF as a fog seal. Fog seal areas were just coated with TF diluted 1W :2TF Please click on the images to enlarge.

Read MoreEngineering Properties of Prime Coats Applied to a Granular Base
By: Gouri Mohan, Kenneth H. Stokoell, and Mustafa B. Erten This study measured the strength and permeability of six prime coats: MC-30, AEP, EC-30, CSS-1H, SS-1H, and Terra Prime. It also evaluated the effects of two application methods: mixing the prime coats into, and spraying them onto, the base course of crushed limestone. Additionally, it tested the penetration of the prime coats into reference sand. This study found that the best-performing prime coat is Terra Prime, followed by MC-30. This study concluded the following: • The dry strength of Terra Prime is five times greater than that of the other prime coats. Additionally, the wet strength of Terra Prime is not significantly lower than its dry strength, whereas the wet strength of the other prime coats is significantly lower than their dry strength. • Mixing the prime coat into, rather than spraying it onto, the base course decreased the permeability of water. MC-30 and Terra Prime exhibited the lowest permeability rates. • EC-30 achieved the greatest penetration into the reference sand, followed by MC-30 and Terra Prime. CSS-1H and SS-1H achieved significantly less penetration, instead forming a sticky surface coat. • Terra Prime performed the best overall, followed by MC-30....
Read MoreTerra Pave Featured in the Austin Business Journal
By Sandra Zaragoza, Austin Business Journal Photo: Austin Business Journal A University of Texas-backed startup has developed a more environment-friendly alternative to a common paving material, and it has raised $1.65 million from investors to help it crack the multibillion-dollar road construction industry. Terra Pave International Inc.—founded by Andres Jackson—is the company behind Terra Prime, the primary use of which bonds the loose bottom layer of road material before asphalt is laid. The founders are touting it to replace MC-30, a type of cutback asphalt prepared by mixing asphalt cement with a petroleum-based solvent. MC-30’s use has raised environmental concerns among engineers—including danger from breathing its fumes, water pollution, and fire—that has prompted some states to ban it and others, including Texas, to limit its use… View full article...
