The invention relates to pavement reconstruction, in particular to a construction method for reconstructing an old concrete pavement by paving an asphalt-concrete surface layer, which is characterized by comprising the following: 1) a step of old concrete pavement processing, which comprises breaking and removing damages blocks and pouring again, mudjacking the old concrete pavement, impacting and rolling old concrete pavement, crack pouring and replacing hardened verges; and 2) a step of paving a asphalt-concrete pavement, which comprises spraying a prime coat and viscous oil and spreading the asphalt-concrete pavement. The breaking and removing damages blocks and pouring again comprise: breaking and removing seriously damaged blocks of the old pavement; shoveling loose parts of an old cement stabilized base away, and pouring concrete in a 15-centimeter thickness which is the same as that of the old base for leveling; filling up the pits on the base with cement mortar and tamping the filled cement mortar; and pouring a 24-centimeter C35 concrete pavement board. In the method, the requirements on cost, quality, construction period, environmental protection and the like are met when the old concrete pavement is reconstruction by paving the asphalt-concrete pavement.
