WK71095 - New Practice for Preparation of Asphalt Mixture Samples for Performance-Related Testing

Work Item

ASTM WK71095

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, conditioning

Rationale

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.
