| Abstract: | Layered steel fiber(LSFRC) and layered hybrid fibers reinforced concretes(LHFRC) are new structure forms for fiber reinforced concrete,which is on the basis of considering economy and improvement of material properties,letting steel fiber layer distributing layer by layer,or synthesis fiber three-dimensional distributing additionally.The study group had studied on fatigue properties of LSFRC and LHFRC for years.As a kind of pavement material,studying its fatigue properties absolutely is the premise of this new composite material becoming extensive use.Fatigue properties were reviewed associating the achievements of the study group,in addition,some achievements and the developing trends of this subject were also discussed. |
