Synchronous Chip Sealer, also known as Macrosurfacing, is a special chip Sealer. It is the use of special equipment that synchronous crushed stone sealing car, through the natural car or roller will be crushed stone and cementing material (modified asphalt or modified emulsified asphalt, etc.) synchronous sprinkling on the road surface, in the rubber wheel roller and natural rolling, forming the protection of the original road surface asphalt gravel wear layer. Its advantage is that asphalt binder and stone spread synchronously, can enhance the bonding force. Due to the small thickness of disposal, its strength is generally not included in the calculation of pavement thickness, and it has little reinforcing effect on pavement structure.
The main applications are as follows:
1. Synchronous Chip Sealer technology can be used as the bottom sealing layer of new pavement, namely, waterproof layer.
2, used for overhaul and expansion of road sealing layer.
3. Synchronous Chip Sealer is used as transitional pavement of low grade roads such as county and township roads.
4, used for the preventive maintenance of old pavement construction. The main purpose is to improve the quality of highway service, reduce capital investment and energy consumption, increase the waterproof performance of the road and extend the service life of the road.
Synchronous Chip Sealer is a new generation of Synchronous Chip Sealer developed by Henan Sinoroader Heavy Industry in combination with years of engineering construction and equipment production practice, combined with market customer demand and feedback, which has a wide range of applications in the field of road construction. It can not only be used for road, urban road, highway and other traffic light control area surface construction, but also can be used for airport, parking lot, industrial plant and other places of pavement construction, gravel, spraying, laying and other functions in one, can be completed in a short time of road surface construction. Its intelligent control system, combined with spraying and laying systems designed for different construction conditions, can ensure high standards of construction quality and maximum improvement of construction efficiency.
