Pneumatic Wheel-Track Molding Equipment is a method for making asphalt mixture test piece according to the industrial standard of China People's Republic of China JTG
E20-2011 "Testing Regulations for Asphalt and Asphalt Mixture of Highway Engineering" The requirements specified in the "" design and manufacture, mainly used for rolling test of
asphalt mixture test pieces before the rutting test.
The test piece can be used for testing the high temperature
anti-rutting ability of the asphalt mixture, and the high temperature stability of the asphalt mixture design, such as the physical and mechanical properties of the asphalt mixture.
The molding machine is an automatic instrument integrating
mechanical, computer, electrical and pneumatic control. Compared with similar products, it is characterized by small size,
high degree of automation, strong function and convenient operation. It is an ideal instrument for roller
compaction molding.
I. Main technical specifications
1.Using a color touch display, instrument operation, data display,
parameter input, etc. can be completed on the touch screen.
2.The display screen displays various parameters such as the
temperature of the roller, the pressure of the roller, and the
number of times of rolling.
3.The instrument is designed with self-diagnosis function, which automatically judges each fault and automatically displays
the fault code.
4.Using advanced air pressure control technology, the roller
pressure can be arbitrarily set and adjusted in the range of (0~20) kN.
5.The height of the test mold can be arbitrarily set and adjusted
within the range of (30~100) mm.
6.The clamping mechanism for installing the test mode is advanced,
safe and reliable.
7.Adopt PWM modulation mode, the drum temperature can be set arbitrarily, the precision is
high, the stability is good,
8.and the drum temperature is displayed in real time.
9.The rolling forming test piece is divided into two processes, each process can be completed automatically, reducing the
operation steps,
and basically completing one key.
10.Designed with safety protection door to ensure the safety of the
operator.
11.With pressure calibration function, the user can calibrate the pressure of the roller on the
instrument.
