On-site recycling machine set used for asphalt ground

Abstract

The invention discloses an on-site recycling machine set used for asphalt ground. The on-site recycling machine set comprises a regeneration heating machine used for heating asphalt pavement with cycled hot wind, a harrowing machine used for a plurality of heating harrowing of the heated asphalt pavement, an asphalt regeneration machine used for collecting and regeneration of asphalt pavement after harrowing, and a pavement paving machine used for paving of regenerated asphalt; the regeneration heating machine, the harrowing machine, the asphalt regeneration machine, and the pavement paving machine are connected with a control center through communication connection; the regeneration heating machine is used for heating asphalt pavement through hot wind negative pressure circulation combustion; the harrowing machine is used for layered heating, and preheating to reduce old pavement surface heating temperature, and then for harrowing of asphalt pavement; the asphalt regeneration machineis used for collecting and regeneration of waste materials of asphalt pavement; and at last, the pavement paving machine is used for paving regenerated asphalt onto asphalt pavement. Paving efficiencyis increased, recycling of waste pavement is realized, and resource utilization rate is increased.

Description

technical field [0001] The invention relates to the field of asphalt pavement recycling, in particular to an on-site recycling unit for asphalt pavement. Background technique [0002] In recent years, my country's highways have developed rapidly. After the asphalt pavement is put into use, various damage phenomena will appear under the combined effects of the vehicle and the external environment. In order to prolong the service life of the asphalt pavement and ensure the road performance of the asphalt pavement, timely Maintenance and repair of asphalt pavement. In the process of maintaining and repairing the asphalt pavement, the old pavement needs to be raked. In order to increase the raking effect, the asphalt pavement needs to be heated before raking. At present, heating and raking are carried out separately by two different equipments, which have low working efficiency and poor raking effect, and the old pavement after raking is generally discarded directly, which incre...

Problems solved by technology

However, in the prior art, in the process of paving asphalt pavement, it is necessary to manually carry out temporary on-site arrangements in various process links, which cannot achieve overall planning and construction, which affects the construction efficiency and even easily leads to omission of related work during the process of laying asphalt pavement. process, requires rework, and wastes a lot of manpower and material resources

Especially prior art does not yet have relevant unit about old pavement heating, harrowing, regeneration, paving, therefore, prior art waits for further improvement and development
