520			_aIn order to study the influence of fiber grid type, fiber grid surface treatment and maximum grain size of coarse aggregate on bending mechanical properties of cement concrete pavement, the beam bending tests and fatigue tests were respectively conducted. The reinforcement mechanism of fiber grid and cement concrete pavement was analyzed. The failure processes of the specimens were analyzed, the mechanical mechanism of the interaction between fiber grid and cement concrete was discussed. The research result shows that brittle failure characterizes the damage of the beam bending specimens. Fiber grid greatly improves the bending mechanical properties of cement concrete, and the bending strength of cement concrete is improved by 6.62 to 31.40 %. When coarse aggregate limiting grain size is 20 mm compared with 40 mm, the bending strength of cement concrete increases by 2.72 to 9.97 %. The bending strength of cement concrete is improved by 8.30 to 11.88 % when the fiber grid surface is treated with epoxy resin. The fatigue strength of fiber grid reinforced cement concrete is higher than that of the plain cement concrete, and the fatigue strength limit increases when the stress ration decreases.
