Different experimental researches were presented. Material properties test explains effects of coarse aggregate gradation on strength and elastic modulus of crumb rubber concrete. Research on three crumb rubber concrete beams with different gradation reveals the impacts of coarse aggregate gradation on flexural capacity, deflection of test beams and so on. Meanwhile, through the analysis of three different coarse aggregate gradation rubber concrete beams, it shows that effects of flexural capacity, deflection, bearing aggregate gradation test beams and researches the fractal behavior of those crumb rubber concrete beams damage evolution process under the concentrated load. Research on evolution process of the fracture of rubber concrete members by using fractal geometry provides a new way for health detection and safety assessment of concrete structure.
