New Practice for Preparation of Asphalt Mixture Samples for Performance-Related Testing
1. Scope
Developed a standard practice for the preparation of asphalt mixture samples that addresses: aggregate and asphalt binder heating, mixing, conditioning in an oven with uniform temperature, compaction, time to sit before cutting/trimming, ambient storage time before testing.Keywords
Sample preparation, performance or performance-related testing, aging, conditioningRationale
Testing lab have found that while we can perform asphalt mixture related tests with a reasonable amount of error (COV 15%) we struggle to repeat the values if the samples are not made in the same lab/same process. This standard practice will propose a uniform method for preparation, conditioning, and storage time of asphalt mixtures to reduce testing variably.
