The invention discloses a steel bridge floor cracking inhibition paving structure and a construction method thereof. The bridge floor paving structure comprises cracking inhibition bonding layers I, wherein the cracking inhibition bonding layers I are paved on the upper surface of a steel bridge floor; the cracking inhibition bonding layers I are firmly combined in sequence from bottom to top and comprise a lower bonding layer I and a cracking inhibition layer I; the lower bonding layer I is made of polymers, and the cracking inhibition layer I is made of fiber reinforced plastics with functions of cracking inhibition strengthening and water prevention. The invention enables the bridge surface paving structure to be firmly bonded with the steel bridge floor, ensures the deformation stress coordination of the steel bridge floor and the bridge floor paving structure and the use performance of bridges, has the functions of water and rust prevention and cracking prevention and resistance and the effect of strengthening the steel bridge floor, greatly prolongs the service life of the bridge floor paving structure and the steel bridge floor, reduces the maintenance cost, and can be finished by simple operation of coating, maintenance, cold mixture and pavement; and a bridge surface paving layer has simple construction process and is economic and durable.
