Specific Gravity Flask for Fine Aggregate— H-3383F

Specific Gravity Flask for Fine Aggregate (The Phunque Flask) is the key element in a newly developed method for conducting specific gravity/absorption determinations for aggregate. This method has been designed to eliminate the inherent guess work built into ASTM C128 and AASHTO T-84— the current cone and tamper methods in use today. The new test is easy to perform, easy to understand and easily reproduceable between technicians and labs. The test is very easy to run and can be reliably run in the field. This can be especially helpful in asphalt operations where specific gravities can make a big impact on pay factors. This test lets the contractor check specific gravities on the material he is currently using, not lab tests, which may not be current.

The H-3388F is for fine aggregate and has a neck approximately 1" in diameter. The scale on the flask is readable to 0.1 grams; Flask also includes an excel calculation sheet and a swabbing utensil to keep the neck of the flask dry during loading.

SSDetect™ Bulk Specific Gravity and Absorption of Fine Aggregates Test System— H-3384.3F

The SSDetect system is a two-part, automated system that determines: Bulk Specific Gravity (dry), Bulk Specific Gravity (SSD), Apparent Specific Gravity, and Absorption of the fine aggregate, all in about one hour. The SSDetect "directly measures" the saturated surface dry condition of the fine aggregate, which is done by way of an infrared light source "tuned" to water. This infrared signal "looks" at the surface of the aggregate for traces of water, and, by measuring the amount of infrared reflectance, the saturated surface dry condition can be accurately measured.

The process involves two samples of a desired material, dried to a constant mass. One sample is placed in the unit's volumetric flask and mounted to the mixing platform of the Automated Vaccum Mixer (AVM), which determines the Apparent Specific Gravity condition. The second sample is placed in the SSD Device where information derived from the AVM test is entered. The SSD Device mixies the sample and injects small amounts of water, allowing the material to absorb water until it reaches the Saturated Surface Dry condition. Once The infrared signal detects a stable SSD condition has been reached the unit will automatically stop and alert the user. The test bowl is then removed and weighed, the net weight of the material is the weight at SSD.
