Gas Hills Road—or WYO 136—in Riverton was becoming a headache for WYDOT, as a portion of the road had continued maintenance issues like rutting and extensive transverse cracking that left the road with major ride issues for drivers. However, the estimated daily traffic numbers made it hard to justify a multi-million project, so WYDOT got creative to find a way to fix the roadway for driver safety while still being fiscally responsible. The solution was use of a three-inch pavement milling with cold in-place recycling along with a fog seal, chip seal, and oil overshoot to extend the life of the roadway.
The project was completed for $1.82 million, saving the State of Wyoming more than $2 million from the original estimate. This project improved the road’s ride, and WYDOT has not found any reflective cracking to date. With the savings, this project is a success and worthy alternative to more costly rehabilitation of the driving surface.
