Specific Gravity Tester LSGT-A10

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.

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
No. Name
1 Constant temperature water bath

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.
