Abstract

The invention discloses a simulation wheel-grind forming machine for bitumen mixture specimens and a specimen manufacture method. The simulation wheel-grind forming machine comprises a grind wheel, a grind wheel driving device, a grind inflating device and a control box. The grind wheel comprises a rim, a retainer ring and a tyre. The outer edge of the rim is provided with the retainer ring. The tyre encircles the outer edge of the rim through the retainer ring. The grind wheel driving device comprises a retarding mechanism, a rack, a hydraulic dowel bar, a hydraulic cylinder, a guide rail and a transmission chain. The retarding mechanism is in power connection with the transmission chain. The top of the hydraulic dowel bar is cooperatively and slidingly installed on a guide rail of the control box. The hydraulic dowel bar is cooperatively provided with the hydraulic cylinder. The hydraulic dowel bar has a telescopic motion bar. The bottom of the hydraulic dowel bar is hinged to the rack. The center of the top of the grind wheel's rim is fixedly connected to the bottom of the rack. The top of the rim is provided with the grind wheel inflating device for inflating the tyre. The simulation wheel-grind forming machine has a simple structure, is reasonably designed and is easy and simple to install, use and operate.

Description

Technical field [0001] The invention relates to the technical field of asphalt mixture material preparation, in particular to a simulated wheel-rolling forming machine for asphalt mixture test pieces and a method for making test pieces. Background technique [0002] In recent years, with the rapid development of my country's economy, as a highway transportation construction business that serves economic development, it has achieved world-renowned achievements. In the structure of my country's highway network, asphalt pavement has the advantages of comfortable driving, good visual effect, low noise, and convenient maintenance. Asphalt pavement is used as the main paving form for all levels of highways. In a large number of indoor tests of asphalt mixture, the formation of asphalt mixture specimens is the basis of all other tests. At the same time, the wheel-rolling method is also an important molding method for asphalt mixture specimens. [0003] However, our current wheel roller f...
