Abstract

Abstract

In order to improve the life of cement concrete bridge deck pavement, compound beam test was used to research the fatigue characteristics of hot mixed asphalt (HMA) courses on bridge deck, finite element analysis (FEA) method was employed to make the mechanical response of compound beam accord with that of actual bridge deck under the same load, the fatigue test was done for compound beams with different pavement structures.Test result shows that the destroy process of compound beam is similar with that of actual bridge deck, the structure with waterproof and cohesive course has a fatigue life, which is 8 times longer than that of the structure without the course, the addition of fiber in the HMA can increase at least 20% of its fatigue life, the combination structure of stone matrix asphalt (SMA) and fiber reinforced asphalt concrete (AC) is the best pavement structure in the test.
