Aggregate Equipment

Barnstead Thermolyne SSDetect

Features & Benefits

Used to determine the specific gravity of fine aggregates using a laser to detect when the sample reaches a Saturated Surface Dry (SSD) state.
This device is a dry-to-wet specific gravity test as opposed to AASHTO T 84 which is a wet-to-dry test.

Gilson Vibro-Deairator with Welch 1405 DuoSeal Vacuum Pump

Features & Benefits

Used to determine the maximum theoretical specific gravity of asphalt mixes by extracting all of the air bubbles within the pore spaces between the material's particles that are submersed in water.
