The performance of fiber asphalt mixture was studied through a series of capability test,such as water stability test,high stability test,low temperature crack resistance test and fatigue stability test.

Based on the functional characteristics of the pavement structure, the article puts forward the selecting method of the fiber asphalt mixture in the application of the pavement structure, and the selecting and determining principles of the fiber materials in the fiber asphalt mixture.

This paper studies the fiber asphalt mixture capability through a series of the capability experiments,such as high and low temperature stability,water stability.

Mechanical performance of fibers-reinforced asphalt mixture;

Marshall index of fibers-reinforced asphalt mixture;

Through the testing of Marshell,low-temperature crack resistance,freeze-thaw split,high-temperature rutting of two kinds of fibers-reinforced asphalt mixtures and the testing road observation,the applicability of fibers-reinforced asphalt mixture to permafrost regions is analyzed.

Low temperature property of fiber-reinforced asphalt mixture;

Discussion on the reinforcement mechanism of fiber-reinforced asphalt mixture;

Based on the micro-characteristics of fibers and te penetration test of fibrous asphalt gel, as well as the low-temperature bending-creeping test of fiber-reinforced asphalt mixtures with 3 kinds of proportions, the effects of fiber addition and proportion on the low-temperature anti-cracking performance of the mixture were analyzed.
