Detailed Product Description
|
Asphalt Test Apparatus ASTM D1665 2 Units Engler Viscometer
Viscosity Tester Summary This instrument is designed and made as per T 0711-2011 Standard
Test Method for Theoretical Maximum Specific Gravity of Bituminous
Mixtures (Vacuum process) in JTG E20-2011 Standard Test Methods for
Bitumen and Bituminous Mixtures for Highway Engineering. It is suitable to determine the theoretical maximum specific
gravity of bituminous mixtures by vacuum process. It is used to
design the ratio of bituminous mixtures, survey the road condition
or calculate the void ratio and compactness of road construction.
It is not available to determine the lacunose bituminous mixtures
which water absorption overs 3%. I. Main technical features 1. It adopts single chip machine technology to vacuumize, shake,
fill air and relieve pressure automatically. 2. Equipped with a high-accuracy absolute pressure sensor, the
negative pressure can reach 3.7 kPa±0.3 kPa. 3. The working status of the vacuum pump can be reflected by a
vacuum meter. 4. It equips a water buffer device to prevent the water in the
negative pressure container from flowing into the vacuum pump. 5. It can determine two samples at the same time. Test efficiency
is high. The structure is reasonably designed. It is easy to use. II. Main technical specifications
III. Optional accessory 1. Constant temperature water bath: WB-1 Low-temperature water bath |
