Bulk Specific Gravity Round-Robin Using the Corelok Vacuum Sealing Device

General Interest: provides practical guidance to engineers responsible for the day-to-day design, construction, rehabilitation, maintenance, and management of pavements.

Primary Topic: Pavement Testing

Description: Research report on a study of the Corelok device for the determination of the bulk specific gravity of compacted hot mix asphalt samples. A total of 21 laboratories participated in the round robin testing of the device. The repeatability and reproducibility of the Corelok device were shown to be similar to AASHTO T166.
