Hot In-Place Recycling: SR-97 West Wapato Road to Lateral A Road (SB)

The construction of the Washington State Department of Transportation's first hot in-place recycling project is documented. The project is located in the eastern portion of the state southwest of Yakima on SR-97. The two southbound lanes for approximately 5.5 miles were recycled using the Pyrotech brand of equipment.

The report also includes a description of the hot in-place recycling process, equipment specifications, a discussion of the limitations and benefits of the process, and a survey of other state DOT's experience with the process.
