Regenerative material lying device for hot in-place regeneration remixer

Abstract

A paving machine of on-site heating recycle material is composed of a spire distribution device and roller. The spire is fixed through a vertical slot on the bracket to the front to the roller. An adjusting rod is in between the spire and the roller for adjusting the comparative level of the two.

Description

technical field [0001] The invention relates to an in-situ heat regeneration remixer for asphalt pavement maintenance, in particular to a recycled material paving device for an in-situ heat regeneration remixer for asphalt pavement. Background technique [0002] Asphalt pavement hot-in-place regeneration process is a new process for asphalt pavement maintenance construction. This construction process regenerates the old asphalt pavement in situ, and can utilize 100% of the original old asphalt pavement materials. The construction speed is fast and the efficiency is high. And save the construction cost, reduce the pollution to the environment and other characteristics, and get rapid development. The hot-in-place regeneration equipment for asphalt pavement mainly includes two types of pavement heating machine and remixer. ), and collected on its double-horizontal continuous mixer, according to the requirements of gradation and oil-stone ratio, add new aggregate and supplement...

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
