Specific Gravity Tester LSGT-A10

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.

Vessel Volume	4000 ml × 2
Power of Vacuum pump	160 W
Negative power	3.7 kPa（27.75 mmHg）
Power of shaking machine	30 W
Power supply	AC(220±10%)V, 50Hz
Dimension	510×520×380 mm

High test efficiency
Test 2 samples at one time
Adopts single chip machine technology
Equipped with a high-accuracy absolute pressure sensor
Vacuum meter showing working status of vacuum pump
Water buffer device preventing water flow from negative pressure container into the vacuum pump

Suitable for measuring theoretical specific gravity of bituminous mixtures. Can also be used for the calculation of the percent of air voids in compacted bituminous mixtures and the amount of bitumen absorbed by the aggregates.
