Our country is already at the forefront of the world in fully utilizing a certain age of asphalt premix worn-out road surfaces. As a country with relatively few resources, we also attach importance to the environment. For asphalt premix roads that have already expired, especially those that are already quite worn-out, we will excavate and recycle them, then crush and screen them. Through these procedures, we can use recycling technology to fully utilize waste asphalt mixtures, which can reduce the investment cost of laying asphalt roads.
The so-called asphalt pavement regeneration technology is actually the use of recycled asphalt mixture crushing equipment to crush and recover the pavement, and then screen it. For example, some particles that meet the particle size requirements can be directly reused through screening, while larger particles can be crushed to achieve the required particle size. After adding some new materials and thoroughly mixing, the road surface can be laid again. Due to the use of only about 30% of this asphalt mixture, the laid asphalt pavement still has strong load-bearing capacity and a longer service life.
For the treated waste asphalt mixture, the addition of rejuvenators, including new asphalt, new aggregates, etc., is carried out according to scientific proportions. This is because our country has high technical requirements when laying asphalt mixture pavement. When adding these new materials, they are strictly mixed according to the requirements and the proportion is followed to ensure that the laid pavement is as sturdy and has strong bearing capacity as all new materials are laid.
The crushing equipment for recycled asphalt mixture mainly consists of a crushing and screening system, as well as a mobile traction frame, etc. Its mobility is also relatively high. During the entire processing and screening of asphalt mixture, the workload is relatively large, and the operation is also convenient and simple. It can greatly reduce labor investment and save the cost of laying asphalt pavement, which is a win-win situation.
The new technology of crushing equipment for recycled asphalt mixture can greatly improve the utilization rate of waste asphalt pavement in our country. As the utilization rate can be increased to over 90%, it can reduce the use of new materials, not only solving the problem of resource scarcity, but also reducing environmental pollution. In addition, on-site operation of the equipment also avoids investment costs during the transportation process. So for construction companies that choose this new technology, it can naturally increase the construction period and reduce the investment cost of asphalt pavement laying.
