In the field of road maintenance, a road maintenance technology called "cold mix cold paving thin layer covering" has emerged. This technology combines cold-mix cold-laid mixtures, cosmetic layer oils, fibers and compounded modified bitumen emulsions.
The emergence of cold-mix cold-laid superviscous fiber abrasion layer mixture system provides a more environmentally friendly and comprehensive solution for road maintenance. It increases the service life of the road, enhances the overall performance of the road, and has the characteristics of low noise. First, a layer of adhesive layer oil is sprayed, and then the composite modified adhesive material and the hot mix ultra-thin overlay graded gravel are mixed and paved onto the original pavement at room temperature, and a new abrasion layer or intermediate stress absorbing layer is formed after repeated rolling.
The cold-mix cold-paved thin-layer overlay combines the advantages of NovaChip and Microsurfacing technologies to form a new road maintenance technology. On this basis, fibers are added to the asphalt mixture to play the role of reinforcement, and polymer modified emulsified asphalt is sprayed in front of the thin layer cover to play the role of interlayer bonding. Through the application of these processes, the technology can effectively improve the abrasion resistance, anti-skid performance, and driving comfort of the road, while also enhancing the waterproof performance and durability of the road.
In addition, cold-mix cold-laid thin layer coverings have a wide range of application prospects. It can be applied to the maintenance of thin layers of asphalt or cement concrete roads at all levels, providing a comprehensive and effective maintenance scheme for different types of roads.
In short, the emergence of cold-mix cold-paved superviscous fiber abrasion layer mixture system has injected new vitality into the field of road maintenance.
