INVESTIGATION OF MOISTURE DAMAGE TO ASPHALT CONCRETE AND THE EFFECT ON FIELD PERFORMANCE--A CASE STUDY

An investigation of premature distress and failure of an asphalt concrete overlay placed in 1979 and 1980 is summarized. The primary objective of the study was to determine the probable cause of the distress. The investigation involved an anaaysis of construction records and laboratory test regults performed during and after construction. In addition, specimens and material were obtained from the roadway for use in a laboratory evaluation. The sampling program included the collection of cores, slabs, and stockpile or pit materials. A description and summary of the pavement and distress, construction procedures, and mixture characteristics, along with the findings related to the probable causes of the distress is presented. The basic causes were that (a) all aggregates and the resulting aggregate-asphalt combinations were highly susceptible to moisture damage and (b) the antistripping additive used in the mixture was not effective.
