T283 TEST BEING TAILORED TO SUPERPAVE

The American Association of State Highway and Transportation Officials (AASHTO) T283 (Resistance of Compacted Bituminous Mixtures to Moisture Induced Damage) is the test procedure most highway agencies use when determining if asphalt pavements are susceptible to moisture-induced damage and thus would benefit from the addition of anti-stripping agents. T283 is relatively inexpensive to use and can be accurate at identifying moisture-sensitive asphalt mixes. The low cost and accuracy of the T283 test procedure led Strategic Highway Research Program researchers to select it for use with Superpave mixes. However, T283 has not been calibrated for use with mix samples produced using the Superpave gyratory compactor. Fine-tuning T283 for use with Superpave mixes should be reasonably straightforward. Until new guidelines on the use of T283 with Superpave mix samples are available, however, highway agencies should pay close attention to the characteristics of their aggregates, which are the most common cause of stripping in asphalt pavements.
