Moisture Damage in Asphalt Mixtures--A State-of-the-Art Report
Primary Topic: Materials-Asphalt
Description: This state-of-the-art report is on the moisture susceptibility of asphalt mixtures used in highway pavements. It addresses the known causes of moisture damage, methods for controlling damage such as antistripping additives, and moisture damage tests. Several other research studies are also summarized in the report. Moisture damage in asphalt mixtures is a complex mechanism which is not well understood and has many interacting factors. This report is mainly concerned with dense-graded hot asphalt mixtures as most of the literature discusses these types of mixtures. Some information on chip seals and emulsion mixtures is also included. One of the intents of this report was to indicate where data is lacking so that research can be performed in these areas.
