Key words: flame retarding asphalt; collaborative system; pavement performance
Abstract: In the pre-stage work, research of flame retarding asphalt with non-flammability level-2 has been completed and experiment and research of the asphalt pavement performance has been carried out.
At present, the research approach of the flame retarding asphalt for tunnels in China is introduced from the successful experience in high molecule flame retardant used in building materials, with proper improvement and applied in the asphalt road surface of tunnels[3].
Experiment materials and flame retarding system In the pre-stage experiment, the flame retarding asphalt with non-flammability level-2 with oxygen index over 27 has been successfully researched, and this experiment is carried out based on the above.
In case of closer tensile stress, if the stiffness modulus is higher, the materials are more brittle and it is more probable to cause crack under sharp changes of temperature.

Abstract.
The material The typical T24 microstructure consists of a 100% tempered bainite.
From Figs. 2-4 it follows that over 800 °C a modest material strengthening occurs.

Abstract.
The reason might be that zinc phosphate on the surface of the carbon steel base plate reacted with carboxyl and hydroxyl in base materials, and they created a complex that formed a tight protective film on the tiny area of the base surface, which protected the metal base from corrosion [3].
