The invention discloses a construction method of an anti-crack concrete pavement. The construction method is characterized by comprising the following construction steps: (1) carrying out pavement base construction; (2) installing a curbstone; (3) drilling a preformed hole on the curbstone, wherein the diameter of a preformed hole is 3-5 mm longer than the diameter of a cold-drawn low-carbon steel wire; (4) installing a prestress tensioning base; (5) after the cold-drawn low-carbon steel wire penetrates through the preformed hole of the curbstone, fixing the cold-drawn low-carbon steel wire on the side surface of the curbstone by using an anchoring piece; (6) tensioning the cold-drawn low-carbon steel wire; (7) pouring concrete: erecting a simple steel bar stool frame before pouring the concrete, wherein a worker and a machine are prevented from contacting with a steel wire during construction, thus reducing the stress loss of the steel wire; (8) shearing the steel wire: shearing the steel wire after the finally poured concrete reaches the design strength of 70%; and (9) sealing the hole of the curbstone: blocking a gap positioned between the curbstone and the cold-drawn low-carbon steel wire by using expanded high-strength cement paste. The construction method disclosed by the invention has the advantages of good anti-crack effect and low cost.
