Shanghai Doan Machinery Technology Co.Ltd can provide crack sealing machine are formulated in a wide range of climatic conditions. All sealant specifications of crack sealing machine meet and exceed ASTM. Doan is the only company that manufacturers road miantenance sealants and the specialized equipment to apply them. They all work together to provide you the confidence that you are receiving the highest quality and innovation.
It is important to understand the components and performance requirements of the sealant. If you choose to thaw the economic benefits with other forms of maintenance or recovery is no longer applicable. Depending on climate and vehicle and pedestrian traffic, appropriate sealants vary depending on each job. In any case, the basic attributes that are required for acceptable performance:
1) Easily and properly placed in the application of crack sealing machine.
2) Adhesion to remain bonded to asphalt and concrete crack faces.
3) Resistance to softening and flow at high pavement temperature.
4)Flexibility and extensibility to remain bonded to crack faces when extended at low temperatures.
5) Elasticity to restrict the entrance of foreign, noncompressible materials.
6) Resistance to degradation from weather.
7) Save time
According to the American Society for Testing and Materials (ASTM), the American National Association of Highway Transport Officers and federal agencies, the best-performing sealant is a polymer-modified sealant that relaxes during complete stretching, Place less adhesive stress on the sealant. The sealant should always be tested on site before installation. The operator must ensure that the sealant package is not damaged.
As an innovated machinery technology company, Shanghai Doan Machinery Company can provide crack sealing machine with highest quality and innovation. Welcome
