Simulated Vibration Roller Forming Machine for Asphalt Mixture Specimen and Method for Making Specimen

Abstract

The invention discloses a simulation vibrating wheel-grind forming machine for bitumen mixture specimens and a specimen manufacture method. The simulation vibrating wheel-grind forming machine comprises a grind wheel, a grind wheel driving device, a vibrating compaction device, a rack and a control cabinet. A hydraulic dowel bar is installed inside a load rack. The grind wheel driving device is in power connection with the hydraulic dowel bar. The grind wheel is in power connection with a hydraulic pressure loading bar of the hydraulic dowel bar. The vibrating compaction device is fixed on the rack. The vibrating compaction device comprises a vibrator used for applying vibration force onto the grind wheel. A rubber vibration isolator is installed between the vibrating compaction device and the rack. A specimen support device comprises a support frame, a forming platform and a specimen mould. The specimen mould is placed above the forming platform. According to the specimen mould, a rectangular specimen mould cavity which is corresponding to the position of the grind wheel is formed by a baseboard and side moulds arranged around the baseboard, and two side moulds divide the rectangular specimen mould cavity into three cuboid specimen mould cavity units with square planes. The simulation vibrating 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 preparation of asphalt mixture materials, in particular to a simulated vibrating wheel mill forming machine for asphalt mixture test pieces and a method for making the test pieces. Background technique [0002] In recent years, with the rapid development of our country's economy, the road traffic construction undertaking serving economic development has made remarkable achievements. In my country's road network structure, asphalt pavement has the advantages of comfortable driving, good visual effects, low noise, and convenient maintenance and maintenance, and all grades of roads use asphalt pavement as the main pavement form. In a large number of indoor tests of asphalt mixtures, the forming of asphalt mixture specimens is the basis of all other tests, and the wheel rolling method is also an important forming method for asphalt mixture specimens. [0003] However, what our current wheel roller forming ma...

Problems solved by technology

[0003] However, our current roller forming machine uses steel arc-shaped rollers, which can only simulate the static pressure process of the steel roller, but cannot simulate the vibration compaction process of the steel roller.
