• Abstract:
  Preliminary work has been completed in an attempt to devise a satisfactory test program to identify water susceptible asphalt paving mixtures. Two different water treatment methods have been applied to one asphalt-aggregate. Five different antistripping additives were evaluated by comparison to control specimens containing no additive. Common laboratory tests were employed to evaluate mixture strength, stiffness and stability before and after exposure to moisture. Tensile strength of mixtures appears to be the best measure of water susceptibility. Resilient modulus shows much potential as a predictor of moisture susceptible mixtures. Generally, hydrated lime added to the aggregate as a slurry seems to offer the best protection from moisture damage.
