¼ Inch Minus Limestone
The trail segment is composed of 6 inches of ¼ inch minus limestone and dust and is 5 feet wide by 50 feet long. The segment contains timber edging. The surface was installed in two rolled and compacted 3 inch lifts. The segment maintained itself well in dry temperatures (June – August; 100 degree temps), remaining hard and compacted under foot. Following the first two days of heavy rainfall uncharacteristic for Indiana, the surface was loose under foot and was bogged down with water. Eventually, the surface developed an erosion ditch measuring approximately 16 feet and at a depth of approximately 3 inches. The surface never firmed back up under foot by the end of fall. After extended periods of no moisture and sun, the surface firms back up under foot.
