The results of fatigue tests on the S-5 mix incorporating a 120-150 penetration asphalt, given in the report on this project issued in May 1971, were incomplete and were somewhat suspect because of mechanical difficulties with the fatigue testing device. Because of the questioned reliability of this set of data in the report, another series of tests were performed, and the results are presented in this addendum.
