Regenerative material lying device for hot in-place regeneration remixer

Abstract

The invention discloses a regenerated material paving device of an in-situ thermal regenerative remixer, which comprises a screw distributing device (7) and a screed (2). ) is provided with a vertical slot hole (9), and the fixing bolts (6) fasten the screw distributing device (7) to the front of the screed (2) through the vertical slot hole (9). An adjusting screw (3) for adjusting the relative height of the two is provided between the screw distributing device (7) and the screed (2). The invention is a recycled material paving device for an in-situ thermal regeneration remixer which reduces material segregation during the paving process of the recycled material, improves the paving quality of the recycled material, has simple structure, is convenient to manufacture, and has reliable performance.

Description

Technical field [0001] The invention relates to an in-situ thermal regeneration remixer for asphalt pavement maintenance, in particular to a reclaimed material paving device of an asphalt pavement in-situ thermal regeneration remixer. Background technique [0002] Asphalt pavement thermal in-situ regeneration process is a new process for asphalt pavement maintenance and construction. This construction process regenerates the old asphalt pavement in situ and can use 100% of the original old asphalt pavement materials, with fast construction speed and high efficiency. It also saves construction costs, reduces environmental pollution and other characteristics, and has achieved rapid development. Asphalt pavement thermal in-situ recycling equipment mainly includes two types of pavement heaters and remixers. During construction, the pavement is heated and softened by the pavement heater, and then the softened old pavement is harrowed by the remixer (without destroying the aggregates i...

AI Technical Summary

Problems solved by technology

There are two structures of the recycled material paving device. One structure is to fix the screw distributing device and the screed together, and lift them together when working. The height between the bottom of the spiral and the bottom of the screed remains unchanged. -40mm or so, but because the paving thickness of the recycled material is small when the remixer is working, the deepest is only 60mm, so the spiral material distribution device can only distribute the part of the material pile higher than the spiral to both ends during the construction process, while the recycled material During the process of material stacking from the mixing tank to the ground, it is easy to cause segregation of large particle size materials deposited at the bottom and the edge of the material pile, but the height of the spiral material distribution device cannot change this situation, which will inevitably affect the quality of the pavement after regeneration

Another paving structure separates the screw distribution device and the screed into independent structures. The screw distribution device and the screed can be raised and lowered independently. Insufficient capacity, recycled materials cannot be completely distributed to both ends, and early collapse and longitudinal cracks are prone to occur on both sides of the pavement regeneration back layer
