Summary
This Automatic Wheel-Track Molding Machine is designed and manufactured in accordance with the requirements of T0703-2011 "Method for Making Asphalt Mixture Test Pieces (Wheel-Rolling Method)" in the People's Republic of China industry standard JTG E20-2011 "Highway Engineering Asphalt and Asphalt Mixture Test Regulations". It is mainly used for rolling and forming the asphalt mixture sample before the rutting test. This test piece can be used for testing the physical and mechanical properties of asphalt mixtures, such as the high-temperature anti-rutting ability of asphalt mixtures, and the high-temperature stability of the asphalt mixture ratio design.
This Automatic Wheel-Track Molding Machine is an automated instrument that integrates mechanical, computer, electrical, and air pressure control. Compared with similar products, it has the characteristics of small size, high degree of automation and convenient operation. It is an ideal instrument for asphalt mixture rolling and forming.
I. Main technical features of WTM-3 Automatic Wheel-Track Molding Machine
1. Using a color touch screen, the operation of the instrument, the display of data, and the input of parameters can all be completed on the touch screen.
2. The display screen displays various parameters such as roller temperature, roller pressure, and roller compaction times in real time.
3. It is designed with self-diagnosis function, which can automatically judge various faults and display fault codes automatically.
4. Using air pressure control technology, the roller pressure can be set and adjusted arbitrarily within the range of (0-20) kN.
5. The height of the test mold can be set and adjusted arbitrarily within the range of (30~100) mm.
6. The clamping mechanism for installing the test mold is advanced, safe and reliable, and easy to use.
7. The temperature of the roller can be set arbitrarily, with high accuracy and good stability, and the temperature of the roller can be displayed in real time.
8. A safety protection door is designed to ensure the safety of the operator.
9. With pressure calibration function, the user can calibrate the pressure of the roller on the instrument.
