The fiber asphalt is studied by a series of capability experiments,such as fiber adsorption of asphalt experiment,fiber asphalt adhesive property experiment,fiber asphalt shear capability experiment.

Based on the reinforced mechanism of fibers, the paper analyze the capacity of fiber asphalt and fiber strengthened asphalt mixture through the test of fiber asphalt ,the Marshall test and pavement performance test of fiber strengthened asphalt mixture.

The model-temperature in road construction is simulated by multi-index orthogonal test,and the characteristics of three mixing methods including the dry-mixing method,wet-mixing method and compound-mixing method are elaborated,and the effects of different mixing methods and model temperatures on Marshall index of fiber-enhanced asphalt concrete are analysed in Marshall test.

The production capacity of the pitch carbon fiber is on a small scale, though the research in out country is carried out for a long time from the beginning, there are great gap compared with the foreign countries in the research and production application.

Block carbon materials with high thermal conductivities were prepared from mesophase pitch fibers by using their high preferred orientation of pitch molecular and appropriate thermoplasticity through a hot-pressing method.
