The present invention relates to a method for resurfacing a concrete pavement using a ready mixed dry mortar, and more particularly, to a method for resurfacing a concrete pavement using a ready mixed dry mortar which supplies, through a mixer, a concrete mixture containing a ready mixed dry mortar obtained by mixing quick hardening cement and dry sand to resurface a concrete pavement in an efficient manner. For this, the method comprises: a step of cutting a road surface to be resurfaced and cleaning the cut surface; a step of mixing quick hardening cement and dry sand to produce a ready mixed dry mortar; a step of mixing the ready mixed dry mortar, gravel, acryl polymer dispersant, water and admixture using a mixer to produce a concrete mixture; a step of placing the concrete mixture all over the cut surface using a spreading machine; a step of texturing the rough cut surface using a texturing machine after the step of placing; a step of curing the concrete mixture in the atmosphere without using a curing agent after the step of finishing the rough cur surface; and a step of constructing a sealant all over the road surface after the step of curing.
