Asphalt waste material recycling process

Abstract

The invention relates to a waste material recycling process, in particular to an asphalt waste material recycling process for recycling waste materials obtained after pavement materials are aged or broken. The process mainly includes the following steps of firstly, preparing a production device and a test instrument; secondly, preparing a recycled material; thirdly, metering the recycled material; fourthly, recycling and regenerating a new material. Through the heat regeneration technology of putting regenerant in asphalt waste materials, waste mixed materials are utilized to the maximum extent, lots of aggregates and asphalt resources are saved, the environment protection is facilitated, and the economic benefits are improved; most importantly, after the recycling technology is adopted, asphalt waste materials become materials with the same performance as asphalt new materials, the complete recycling standard is achieved, maintenance and pollution cost is greatly reduced, and economic benefits are remarkable.

Description

technical field [0001] The invention relates to a recycling technology for waste materials, in particular to a recycling technology for asphalt waste materials that are planed out after aging or damage of road paving materials. Background technique [0002] Environmental protection in the new era is already a problem that cannot be underestimated. The accumulated waste from asphalt pavement has become a huge burden in every country. In many countries, the industry will choose to backfill on site or stack in the factory, but the waste is ignored. The asphalt is rich in asphalt. Over time, the asphalt flows into the underground soil layer to pollute the limited land on the earth, and the stacking of the factory area often severely paralyzes the production of the factory area with limited land; when the asphalt concrete construction reaches the service life, it needs to be removed.

[0002] Environmental protection in the new era is already an issue that cannot be underestimated. The accumulated waste from asphalt pavement has become a huge burden in every country. In many countries, the industry will choose on-site backfill or stack in the factory, but the waste is ignored. The asphalt is rich in asphalt. Over time, the rain asphalt flows into the underground soil to pollute the limited land on the earth, and the stacking of the factory area often severely paralyzes the production of the factory area with limited land; when the asphalt concrete construction reaches the service life, it needs to be removed. Or dig out and re-pave. After proper disposal, the old asphalt concrete can be used as construction material again in the newly paved road surface. However, the properties of the recycled asphalt concrete are far away It is not as good as the newly produced asphalt concrete. For example, the Chinese patent application number is 201410492652.1, and the patent name is a method for pretreatment of waste asphalt reclaimed materials. Although the excavated asphalt waste is pretreated, the utilization rate of waste and old asphalt reclaimed materials is greatly improved and resources are saved. However, the invention does not disclose how to regenerate the technology, nor can it fully utilize the planed waste, and there is no data to prove the performance comparison between the pretreated material and the new material
