Abstract: This paper introduces different types and properties of synthetic macro-fiber.Based on experimental research,the mechanical properties and endurance of shaped synthetic macro-fiber reinforced concrete presented with emphasis.The mechanical properties and endurance include the flexural strength,flexural toughness, flexural impact resistance,fatigue resistance,uniaxial tensile strength,fracture performance,erosion resistance and so on.Moreover,when synthetic macro-fibers are applied to road and bridge engineering,technological problems in design,in confection,and in construction,and application prospects are also proposed herein.
