GLEN ELLYN, IL, March 9, 2022 – At the 49^th Annual Meeting of the Asphalt Emulsion Manufacturers Association (AEMA), February 22-25, 2022, the TxDOT-San Angela District, Junction Area, Ergon Asphalt & Emulsions, and Intermountain Slurry Seal were awarded the 2022 AEMA Past President’s Award for Emulsion Excellence for their TxDOT Improves Safety on I-10 by Using Micro Surfacing and Rejuvenating Fog Seal project.

This award is presented in recognition of a specific project utilizing asphalt emulsions completed in the past calendar year and is awarded to the agency, contractor, and emulsion manufacturer of the winning entry.

The Texas Department of Transportation works to match surface characteristics to traffic conditions of a road when choosing the appropriate applications. I-10 is a high-speed road which the speed limit is posted as 80 MPH and an ADT of 11,000 with 40% being trucks. Surface friction is critical to improve driver safety and it was determined the best solution for I-10 would be a 10-year-old micro surfacing treatment to produce best results. TxDOT also chose to apply a rejuvenating fog seal to the shoulders as it adds a safety feature of preserving and extending the life of the highway shoulders.

The project started on August 3, 2020 and was completed on September 1, 2020. Micro surfacing was applied at 22 pounds per square yard along the 96-lane mile stretch with the treatment being applied in two-mile increments. Traffic was shifted to one lane during application. The rejuvenating fog seal emulsion was applied to the shoulders at 0.10 gallons per square year. Both treatments cured in less than an hour and traffic was returned to normal.
