This gyrotary compactor is a reference to the People's Republic of China transportation industry standard JT/T 724-724 “rotating compaction instrument”, JTG E20-2011 Standard Test Methods for Bitumen and Bituminous Mixtures for Highway Engineering of T 0736-2011 the “asphalt mixture spinning compacted specimen method (SGC)” requirements, and the association of American material experiment D6925 ASTM standards, the American association of state highway and transportation officials AASHTO T312 standard, etc..
And absorb the advanced technology of the gyratory compactor, learn widely from others' strong points and the design and manufacture. Compaction method is applicable to electric pneumatic rotary forming Φ 150 mm or Φ 100 mm (Separate purchase) emulsified asphalt and asphalt mixture , cold recycled mixture in the cylinder specimen compacted molding. In order to the lab to do the test on physical and mechanical properties of asphalt mixture.
I. Main technical features
1. This compaction equipment uses high hardness and high quality steel as a framework, to ensure accurate angle control.
2. Electro-pneumatic servo control regulation.
3. Color display touch control system, can be directly connected to the computer, through the interface of microcomputer can display a variety of curve table, and with the touch screen bumpless connection, joint control over the instrument.
4.This superpave compactor can be easily set the angle of the rotation compaction, compaction pressure, rotating speed, the number of rotation and other test parameters.
5. Compaction process that can be measured and real-time display test rotation angle, compacting pressure, specimen compaction, rotation number and other important parameters.
6. The operation of the compaction test result can be saved, draw, printed and so on.
7. Two kinds of operation modes to complete compaction experiment: ⑴ preset number of revolutions, ⑵ pre-specified height.
8. Interface configuration: 1 USB interface, 1 RS232 interface.
9. The integration of the built-in ejector.
10. Can do the heating insulation of the tryout rotation studio (optional).
11. Used for emulsified asphalt and cold recycled mixture compaction experiment.
