Specific Gravity Tester LSGT-A10 determines the theoretical maximum specific gravity of bituminous mixtures in accordance to ASTM D2041 Standard Test Method for Theoretical Maximum Specific Gravity of Bituminous Mixtures (Vacuum process). Adopted with single chip machine technology to shake a loose asphalt mixture sample submerged in water. Vacuum is applied into the sample, to extract out the air bubble.
