What is Track-Out Rock? 🚜🛑

Track-out rock (also known as construction entrance rock, tire wash rock, or stabilization rock) is a type of coarse, angular rock used at construction site entrances and exits to prevent mud, dirt, and debris from being tracked onto public roads. Track-out rock is a type of coarse, angular stone, typically ranging from 3 to 6 inches in size, used to stabilize construction site entrances and exits. Its primary purpose is to minimize the amount of sediment, such as dirt and mud, being tracked out from the construction site by vehicles. The angular shape of track-out rock helps remove debris from vehicle tires, reducing sediment transport onto public roads. It’s commonly placed in a controlled exit area about 50 feet long, 10 feet wide, and 6 to 12 inches thick. Maintenance includes using a loader to scarify the sediment-laden rock to “fluff” it up.
