Premature AC Pavement Distress. District 2 Investigation. Final Report
In this study, the moisture sensitivity of several conventional asphalt concrete and asphalt-rubber mixes was assessed. This included an evaluation of (1) the effect of hydrated lime on the moisture sensitivity of (AC) mixes, (2) the use of AASHTO T283 in assessing the moisture sensitivity of AC mixes, (3) the effect of variations from the optimum bitumen content on the moisture sensitivity of AC mixes, (4) the effect of changes in air voids on the moisture sensitivity of AC mixes, (5) the moisture sensitivity of asphalt-rubber mixes, (6) the effect of maximum aggregate size on the moisture sensitivity of AC mixes, and (7) the potential use of the controlled-strain fatigue beam test in evaluating the moisture sensitivity of AC mixes. The maximum aggregate size appeared to affect the moisture sensitivity of AC mixes. Asphalt-rubber mixes were found to be more sensitive to moisture than conventional dense graded asphalt concrete mixes. The fatigue beam test results indicated that the test has a potential use in moisture sensitivity evaluation.
