Problems solved by technology

This will inevitably cause the rolling wheel to turn back on the surface of the uncompacted asphalt mixture specimen.
However, in engineering practice, we do not allow the road roller to turn back on the uncompacted asphalt road section

Abstract

The invention discloses a comprehensive wheel rolling former for an asphalt mixture test specimen and a test specimen manufacturing method. The comprehensive wheel rolling former for the asphalt mixture test specimen comprises a load frame, a rolling wheel convertor, a specimen support device, a rolling wheel drive device and a control box. The rolling wheel drive device is arranged on the control box; the load frame and the control box are connected and fixed; the rolling wheel convertor is arranged in the load frame; a hydraulic dowel bar A and a hydraulic dowel bar B are arranged on the bottom part of the rolling wheel convertor; the rolling wheel drive device is in power connection with the rolling wheel convertor; the rolling wheel convertor is used for respectively transmitting hydraulic power to the hydraulic dowel bar A or the hydraulic dowel bar B; an outer wall of the hydraulic dowel bar A is in power connection with a rolling wheel through a rack I; an outer wall of the hydraulic dowel bar B is in power connection with an air-inflated rubber wheel through a rack II. The comprehensive wheel rolling former for the asphalt mixture test specimen provided by the invention has the advantages of simple structure, simplicity and convenience in operation, good using effect and the like.

Description

technical field [0001] The invention relates to the technical field of asphalt mixture test equipment, in particular to a comprehensive 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, our current roller forming machine uses arc-shaped rolle...
