Scrub seal highway rehabilitation project set for August south of Ten Sleep

TEN SLEEP — A $1.1 million pavement rehabilitation project is scheduled to begin Aug. 6 on Wyoming 434 (the Big Trails Road) south of Ten Sleep.

The project is slated to begin on the south edge of Ten Sleep (milepost 0.267) and it extends nearly 15 miles south to milepost 15.

"Crack surfacing is scheduled to begin next week (mileposts 7.75 to 11), with the scrub seal portion of this project starting about Aug. 19," said Wyoming Department of Transportation resident engineer Kaia Tharp of Thermopolis."

Prime contractor is Intermountain Slurry Seal, Inc., of Salt Lake City, Utah.

A scrub seal is a roadway surface treatment that involves applying a spray-on (oil) emulsion with a higher viscosity, followed by a broom trailer that forces the emulsion into the cracks. A light coverage of fine rock is applied to the emulsion to provide some surface skid resistance. This treatment weather-proofs surfaces and adds skid resistance. It’s used as a final surface for low volume/traffic conditions, such as those that exist on the Big Trails Road.

Motorists should expect delays of up to 20 minutes and reduced speed limits while pavement work is under way.

Contract completion is Aug. 31, 2019.
