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....

Background On Thursday, March 6, 2014, Cox Paving Co. performed preventative maintenance on traffic lanes on 1st Street near Slaughter Lane in Austin, Texas with Terra Fog from Terra Pave International. Terra Fog is a special water based eco- friendly polymer compound. Application Area Terra Fog was applied to sections of 1st Street for a distance of about one mile south from the intersection with Slaughter Lane. The road surface was originally covered with a grade #5 chipseal, and substantial amounts of loose aggregate rock from the failing sections of the old seal where visible along the curbs of the street. Loose chips were also visible on the road surface itself, in addition to holes and gashes in the chipseal. Daren Duncan, P. E. City of Austin “We have a test section [of Terra Fog] in the backyard of the Streets and Bridges Department, and we wanted to use that to see how the material held up under heavy equipment and lots of turning movements. And that test section held up pretty well, with all the heavy equipment and turning. The most interesting thing is how quick it set up––about 15 minutes. Also, we were very interested in the tire tracking, because of how hard it is to keep people from driving over and tracking.” Advantages of Terra Fog The advantages of Terra Fog are multi fold: Environmentally Safe – Terra Fog includes no VOC’s and evaporates only water. Surface Strength – Terra Fog will do an excellent job of locking down all of the aggregate and additional aggregate loss is unlikely. Curing Time – When placed with good drying conditions, Terra Fog could be crossed with no tracking in less than 10 minutes and was ready for traffic in approximately an hour. Continued curing will occur for 24-48 hours. Impermeability – The surface is completely impermeable, very effectively shedding water. It will penetrate into pavement cracks and will do an excellent job at sealing minor cracking. Aging – Terra Fog includes carbon black and has excellent ageing characteristics. By sealing air and water out of the asphalt pavement, it will substantially reduce oxidation of the asphalt and extend pavement life. Here is the video of the application. ...
