Corelok Bags, 11 x15 In, Channeled , for Rice Test,100/Roll

Maximum Specific Gravity (Gmm) Max Specific Gravity Specification ASTM D6857
This method may be used as an alternative to the conventional “Rice Test” for the determination of maximum specific gravity of loose asphalt mixtures. The CoreLok® test can be completed in seven minutes with minimal exposure to water, eliminating the need for a lengthy “Dry Back” method.

This procedure requires that a sample of dry asphalt mixture is placed inside the vacuum bags and sealed within the CoreLok® vacuum chamber. The bags are then cut open underwater and a submerged weight is determined. The weight in air and the submerged weight can be used to calculate the maximum specific gravity of the asphalt mixture.
