EXPERIMENTAL STUDY ON BENDING STRENGTH OF CRUMB RUBBER CONCRETE FOR PAVEMENT

As a new style material in concrete field, crumb rubber concrete is providedwith perfect ability of holding backcrack, better resistance to shock load and better energy dissipation, and is very suitable for new pavement material. Theprimary study on bending strength of crumb rubber concrete is done. The main factors of affecting bending strength of crumbrubber concrete are analyzed by the study on bending strength of crumb rubber concrete with more crumb rubber (max to150kg /m 3 ), and empirical formula is created, also, the rationality of the formula is validated. It is discussed and analyzedthatthe correlation between bending strength and compressive strength of crumb rubber concrete, and the correspondingempirical formula is also created.
