To improve the graded crushed rock road performance, a new technical measure was taken to add the fibers to graded crushed rock mixtures. Using vibration as molding method and splitting strength as the standard, the type, dosage and length of fiber were optimized. Using the self developed graded crushed rock shear apparatus, the influence factors of the shear strength of fiber graded crushed rock were systematically studied. At the same time, the fiber graded crushed rocks rutting resistance performance was studied. The experiment results show that when the confining pressure is 50kPa, the fiber graded crushed rock maximum shear strength can be increased by 27 times; water content, compaction degree and maximum particle size have significant effects on the shear strength; with the water content increasing, the shear strength decreases; the greater degree of compaction, the bigger the shear strength becomes; the fiber graded crushed rock with small particle size has a bigger shear strength. Rutting test results show that the adding of fibers significantly improved the rutting resistance of graded crushed rock. Construction test results show that the fibers self developed can be evenly dispersed in the graded crushed rock mixtures; the surface deflection of the fiber graded crushed rock base is less than that of the ordinary graded crushed rock base; it has also been shown that fiber graded crushed stone flexible pavement can be used for heavy traffic.
