Every year in our country, over 10% of asphalt pavements that have reached the end of their service life undergo either minor repairs or major repairs. If major repairs are carried out, it is necessary to thoroughly crush and recycle the asphalt pavement in order to reduce environmental pollution and lower the investment cost of asphalt pavement installation. However, if manual crushing of waste asphalt pavement is relatively costly and inefficient, it is better to choose emulsified asphalt crushing and screening equipment, which can greatly improve work efficiency.
The reason why many asphalt pavement laying companies are willing to choose emulsified asphalt material crushing and screening equipment now is because of its high work efficiency. It can crush and screen the old and expired asphalt pavement. For usable materials, they can be directly screened and utilized. For asphalt pavement materials with larger block sizes, they need to be crushed again until they are crushed into reusable particle sizes, and then new materials can be added. After mixing evenly, the asphalt pavement can be laid again. So this method is a good approach for both asphalt pavement maintenance and large-scale road surface renovation.
The emulsified asphalt crushing and screening equipment mainly includes a screening box, in which multiple layers of screens are set up from top to bottom. Each layer is uniformly framed along the edge of the screen, and two sliding tracks are also set up, which are fixed on the two inner walls of the screening box. The sliding tracks are composed of two parallel sliding boards, and the frame is located between the two sliding boards, so the screening effect is relatively good.
Due to the fact that the equipment for crushing and screening emulsified asphalt materials combines crushing with screening, and the loading can be done with the help of forklifts, its work efficiency far exceeds that of manual crushing and screening. Only one equipment like this is needed for road construction to meet the demand for asphalt pavement waste materials. Because asphalt waste materials can be mixed with new materials during use, and the amount of mixing is generally over 30%. With only 30% of waste materials, road construction can save a lot of investment costs.
In order to better recycle old asphalt pavement, only by using emulsified asphalt material crushing and screening equipment can the recycling force be greater. Due to its high degree of mechanization, high level of intelligence, and simple operation, more and more asphalt pavement companies are willing to choose this equipment when choosing to recycle old asphalt pavement materials.
