Research conclusions：The structure of continuous reinforcement concrete pavement has no expansion joints in lateral or longitudinal direction. But because of temperature load, about 3 to 5 centimeters displacement may occur within 75 m regions of the free end. So the anchor device is installed in the end part or expansion joints are usually laid in many places to spread and eliminate the displacement in end part. The crack width of continuous reinforcement concrete pavement should be less than 0.6 mm without severely seepage, and it should be less than 1.0 mm under condition of low temperature. The reinforcement ratio is about 0.5% to 0.8% and reinforcement is of single-layer. The pavement slab should be laid on bitumen-treated basis layer or leveling course to better control the lateral crack width. For the German double-block slab ballastless track, the reinforcement ratio is 0.8% -0.9%, the crack width of designed control is 0.5 mm, the gap between cracks is about 2 m, and the reinforcement is laid on the middle or low layer with single-layer. For Chinese CRTSⅠ double-block slab ballastless track, the design slab thickness is 260 mm and the reinforcement is of double-layer in order that the slab can bear bigger bending deformation.
