At present, the country vigorously advocates for "green environmental protection" and "protection of natural resources". Asphalt concrete waste can also be effectively utilized to achieve these two aspects. The method is simple, which is to crush and screen the old asphalt recycled material, then add recycled asphalt reducing agent and a small amount of new aggregate, mix it with asphalt thoroughly, and then use it for road laying.
There is a need to find a professional manufacturer of asphalt recycled material crushing, crushing, and screening equipment for relevant construction needs, which can effectively achieve the overall asphalt regeneration operation process. A regeneration material bin is added below the top of the discharge of the primary crushing and feeding belt conveyor, which can temporarily store the crushed materials of the primary crusher and also serve as a feeding bin for small particle sized recycled materials, Effectively solve the problem of timely adding recycled materials when the output of the primary crusher is insufficient, ensuring the normal operation of subsequent processes, and thereby improving the screening efficiency of the crushing and screening equipment, as well as the crushing and screening efficiency of recycled materials.
In addition, in order to improve the road performance of recycled asphalt recycled materials, a circulation structure composed of a feeding belt conveyor, a vibrating screen, a secondary crusher, and a return belt conveyor can be created. The oversized materials in the vibrating screen can be crushed twice and then sent back to the vibrating screen for re screening, in order to achieve the extremely matched particle size of material crushing.
In this way, it can effectively solve the problem of high engineering costs. With good crushing and screening equipment, there is no need to worry about the high cost of maintenance and renovation of asphalt roads, and there is no need to worry about occupying a large space and high geological conditions. It can be used anytime, effectively helping to shorten the construction period of the project, and the good asphalt regeneration effect can effectively avoid a large amount of old asphalt recycled material stacking Environmental pollution caused by landfill.
It is worth noting that in the technology of plant mixed hot recycled asphalt, the construction process and quality control are very important. Among them, there are high requirements for the quality of the newly added recycled RAP material, including water content, grading, asphalt content testing, and other items. The standards must meet the requirements of the specifications, and the viscosity and penetration of recycled asphalt must be tested with emphasis, Better ensure that the production process and construction of asphalt recycled materials have good results.
