DSHD-0711A Bitumen Mixtures Theoretical Maximum Specific Gravity 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
E20011.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%.
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.
Main technical specifications
1. Power supply: AC(220±10%)V, 50Hz.
2. Volume of vessel: 4000ml×2
