City of Austin, Texas – Terra Fog

City of Austin, Texas – Terra Fog

City of Austin test section at the parking lot of the Department of Public Works in Austin, TX. Terra Fog is a water-based and environmentally friendly fog seal 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. Lab studies have shown that Terra Fog performs well at retaining chips when applied over a chip seal. It also is safe to use in Ozone Nonattainment Areas, like crowded cities and metropolitan areas, since it does not emit any volatile organic compounds (VOCs). Almost 50% of aggregates are lost due to weather and traffic within a couple of years after construction; however, lab tests have shown that Terra Fog prevents aggregate loss completely. Terra Fog extends the service life of asphalt pavements and forestalls drastic maintenance, such as resurfacing and seal coating, by preventing water from infiltrating the base. It prevents aging of the pavement by stopping oxidation, and it penetrates the pavement and seals loose particles, thereby improving the pavement’s structural matrix. Terra Fog also seals small cracks, coats loose surface particles, and defines and maintains road shoulders. Terra Fog 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 VOCs. It does not contain solvents or cause damage to roads or vehicles. Terra Fog is patented by the University of Texas at Austin and licensed exclusively to Terra Pave International, Inc.

Collingsworth County, Texas – Terra Fog

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.

Round Rock, Texas – Top Seal White

Base stabilization with Top Seal White – Round Rock, TX Top Seal White is used for base stabilization to achieve a highly dense base by preserving the optimal humidity and the pressure of compaction. The treated base behaves like a cement-stabilized base but it is flexible. TSW preserves the base from weather conditions and forms a wearing surface. The base becomes impermeable and rock solid, and over time it doesn’t lose any aggregate. Also the surface is free from dust, as TSW could be used at very low rates as a dust control agent....
