¾ Inch Minus Limestone
The trail segment is composed of two three inch lifts of ¾ inch minus limestone and approximately 50 percent dust. This trail segment is 5 feet wide by 200 feet long. The segment contains timber edging. This trail segment maintained itself well in dry temperatures (June – August; 100 degree temps), remaining hard and compacted under foot. After the same two days of uncharacteristically heavy rainfall (as noted in the ¼ inch minus segment), the surface had evidence of water pooling on the surface, as there were lines of pine needles but the surface remained unchanged. It was still firm under foot through the end of the testing in fall. The surface does have a prevalence of the larger fines working their way to the surface, but not affecting the way in which the surface is bound to keep it firm. It would be an item to consider when evaluating the intended use of a trail for those visitors using mobility devices and assistive devices such as crutches and canes.
