Description:

The performance of the stress absorbing membrane innerlayer was evaluated between 1977 and 1982. Benkelman Beam deflections were measured, cores taken at selected crack locations to determine their origin, and visual inspections wre made to check for rutting, raveling, and cracking. The evaluation noted the start of transverse cracking two years after construction and significant transverse cracking throughout the project after five years. Fine map cracking as small as two-inches square predominated in the outside lane. Some of the small cracked segments had been dislodged by traffic.
