Summary
The instrument is designed and made as per T0703-2011 “Bituminous Mixtures Sample Making Method (Wheel-grind Method)” in the Industry Standard of People’s Republic of China JTG E20-2011 Standard Test Methods for Bitumen and Bituminous Mixtures for Highway Engineering. It is suitable to mill bituminous mixtures to molding .It is also suitable to determine the sample making method (wheel-grind method) for other physical and mechanical characteristics of bituminous mixtures.
This instrument is an automatic instrument integrating machinery, computer, electric and air pressure control. Compared with the similar products, it has the advantages of small volume, high automation, strong function and convenient operation, so it is an ideal instrument for asphalt mixture compacting forming.
Main technical features
1. With color touch screen, the operation of the instrument, data display and parameter input can be completed on the touch screen.
2. The display screen shows the compacter temperature, compacting times and other parameters in real time, and has the function of self diagnosis.
3. It has the function of real-time display and inspection of compacter pressure to ensure that the test is carried out under the correct compacter pressure.
4. It has the automatic alarm function when the compacter pressure exceeds 3% of the set pressure to inform the operator to respond accordingly.
5. With advanced air pressure control technology, the compacter pressure can be set and adjusted in the range of (0 ~ 20) kn.
6. The height of the test mold can be set and adjusted in the range of (30 ~ 100) mm.
7. The fixture structure of test model is advanced, safe and reliable, and easy to use.
8. There are two processes for compacting forming specimens, each of which can be completed automatically, reducing the operation steps and basically realize one-click-to-complete.
9. The front left and right opening safety protection door is designed to ensure the safety of the operator.
10. With the function of pressure calibration, user can calibrate the pressure of the compacter on the instrument.
