Cold Recycling Process

In cold in-plant recycling, the old asphalt pavement material is removed by a milling machine and then transported to a plant where it is crushed, screened, and combined with a certain percentage of new aggregates, asphalt, active fillers and water under normal temperature to form a base course for reconstructed pavement.
This technology can not only improve the performance and prolong the service life of asphalt pavement, but also can yield significant savings in materials, thus reducing the project cost. According to a survey undertaken by the U.S. Federal Highway Administration, the asphalt pavement recycling can help save 50% asphalt and reduce 25% pavement construction cost.

Features
1. The cold in-plant recycling equipment adopts twin horizontal shaft stirrer which offers high speed and ensures complete mixing of all materials.
2. The use of impeller type powder feeding spiral results in accurate powder delivery.
3. A special device installed on the bottom of the powder hopper enables the powder to flow smoothly in the hopper, thus achieving uniform powder delivery.
4. The lightweight, vibration-free powder spiral contributes to the improved measurement precision.
5. The intelligent control system adopts PLC control and computer indicator for easy operation.
6. The modular design of the cold in-plant recycling equipment offers users benefits such as easy installation, convenient maintenance and quick removal of the equipment.

Application
The cold in-plant recycling equipment can recycle the damaged pavement material and the reclaimed asphalt can be used in the base, sub-base layer of asphalt pavement for expressways, first and second grade highways, as well as the surface layer of asphalt pavement for third and fourth grade highways. After rehabilitation, the road pavement is less liable to crack and can be used for a long time. Functional, economical and eco friendly, our cold in-plant recycling equipment is a product of choice for customers worldwide.
