We must pay special attention to the maintenance of highways, because to a certain extent it is related to people's lives, health and safety. The means and methods of road maintenance must evolve with the development of the times, and constantly adapt to social needs and the development process of highway technology. In recent years, the use of thermal asphalt recycling to repair road potholes and other diseases is one of the more advanced pavement maintenance technologies. So what are the advantages of using asphalt hot recycling?
Asphalt hot recycling technology can be roughly divided into two types: plant mix regeneration method and hot in-place asphalt recycling method. The appropriate method needs to be selected based on the specific requirements of the project. The overall strength of some highways has not declined after long-term use, but there are cracks, potholes and other problems on the road surface. The asphalt pavement recycling method can work on the original pavement. It has the advantages of low price and environmental protection, and is suitable for promotion in highway pavement maintenance.
When using traditional methods to repair highway pavement, the pit walls of the original pavement are cold during the construction process. After adding the new mixture, a cold joint will usually be formed between the old and new asphalt concrete materials. When cars drive over the road surface and on rainy days, water will penetrate into the joints, destroying the bond between the asphalt mixture materials, thereby shortening the service life of the entire highway after repair. Asphalt hot recycling technology can effectively avoid this problem. Through heating and the addition of regenerant, the original pavement asphalt concrete can restore its previous performance, and the connection between the old and new asphalt mixtures will be tighter and stronger, greatly extending the service life after repair. At the same time, asphalt recycling technology reduces the need for new asphalt concrete by restoring the performance of the original asphalt pavement materials and recycling them, making it more environmentally friendly and economical.
In addition, highway maintenance using asphalt recycling technology is not affected by time and climate. Whether it's day or night, in hot or cold zones, asphalt hot recycling technology can be used for pavement repair. The lane occupied by the construction is also very narrow, and the impact on normal traffic will not be great.
These advantages of asphalt hot recycling technology make it more and more widely used in the early disease repair of highway asphalt pavement. And a cheap, easy-to-use, high-quality asphalt recycling machine is becoming a wise choice for more and more road maintenance workers!
