National Trail Surfaces Study

Stabilizer

The trail segment is composed of the stabilizer, Stabilizer, and is 5 feet wide by 50 feet long. The segment contains timber edging. The Stabilizer is applied to a base of 3 inches of compacted native soils. Stabilizer arrives pre-mixed with ¼ inch minus aggregate and is applied at a 3-inch depth on top of the base. The surface maintained itself for the most part through the first round of testing after installation (June – August; 100 degree temps) with the exception of loose fines that appeared on the surface. After the heavy rainfall, the surface had runoff composed of the loose fines from the trail segment. It was not until the testing conducted in March 2008 that the surface showed large signs of deterioration. There were gullies created in the surface because of runoff; these were found both down the middle of the trail segment and along the timber edging. The surface would need maintenance to return it to its original state.
