Effect of Moisture and Aging on Asphalt Pavement Life. Part 1. Effect of Moisture
Research has been carried out on the effect of water on asphalt mixtures, and test methods to investigate the effect of water have been developed. However, most of the work has been related to stripping and the effect of additives, where external water enters or affects the pavement following construction. The report presents the results of a study to investigate the effects of mixing moisture on mechanical properties of asphalt mixtures. The potential benefits of lime and Pavebond Special were also investigated. The repeated load diametral test device was used to measure the resilient modulus, fatigue, and permanent deformation characteristics of laboratory specimens prepared with and without moisture (0, 1, and 3%) and with and without lime (0, 1%) and Pavebond Special (0, 0.5%). Mixtures were prepared which were representative of two projects for which considerable field data were available. One project utilized marginal aggregate and the other good quality aggregate. To evaluate the long-term durability of mixtures, they were tested before and after conditioning using the Lottman approach.
