The invention discloses a reusable temporary road plate construction method. The method comprises the following steps: (1) preparation: detecting elasticity modulus of foundation, ground flatness, reinforcement amount, reinforcement protection layer thickness, concrete strength, and straightness of a template; (2) subgrade treatment: filling the road for laying the road plate, compacting and leveling the road, and spreading a sand cushion layer piecewise by mechanical spreading in piles; (3) template installation: laying waterproof plastic cloth on the road with the sand cushion layer, paying off, and fixing the template at the pay-off positions on the plastic cloth; (4) reinforcement binding; binding an upper and a lower layer of reinforcements on the mounted bottom template, and placing a reinforcement protection layer cushion; (5) concrete casting: casting concrete on the template bound with the reinforcements; (6) maintenance and template removal: watering and maintaining concrete, and removing the template; and (7) road plate removal. The reusable temporary road plate construction method provided by the invention has the advantages of long service life, energy conservation and environmental protection, and can reduce the discharge of construction wastes.
