Description

technical field [0001] The invention belongs to the field of road engineering, and relates to road maintenance equipment, in particular to a stress absorption belt preparation and paving device. Background technique [0002] The "white plus black" reconstruction technology refers to the technology of maintaining the integrity of the old pavement, taking measures such as grouting under the slab, partial replacement or repair, and then directly adding an asphalt overlay on the old cement concrete pavement. This method can make full use of the remaining structural strength of the old cement concrete pavement and reduce the overlay thickness. However, the problem of reflective cracks in the overlay layer faced by this technology has always been one of the difficult problems faced by the highway industry. The existence of reflective cracks not only destroys the overall strength of the pavement structure, but also causes the surface layer to gradually lose viscosity and fall off ...

AI Technical Summary

Problems solved by technology

However, the problem of reflective cracks in the overlay layer faced by this technology has always been one of the problems faced by the highway industry.

The efficiency of this method is low, the material of the stress absorbing belt is scattered more, and the waste of material is serious

In addition, the brushing tool does not have heating equipment, and the material of the stress absorbing belt has a high viscosity, which gradually sticks to the brushing equipment during construction, which is extremely inconvenient to operate

The existing stress-absorbing belt paving equipment is only suitable for the mechanized construction of a single-layer stress-absorbing belt, and cannot solve the problem of integrated construction of the stress-absorbing belt, which seriously affects the integration of the upper and lower layers of stress-absorbing materials, and the existing equipment is difficult Guaranteed the thickness and flatness of the stress-absorbing band
