The invention discloses an antiskid and warping deformation preventing temporary pavement underboarding device and a method. The device provided by the invention solves the problems of small surface friction coefficient and easy warping deformation in traditional steel plates, and has the beneficial effects of prolonging the service life of underboarding device, realizing recycling, and effectively reducing the noise pollution of traditional steel plates to city. According to the scheme, the antiskid and warping deformation preventing temporary pavement underboarding device comprises a rigid support plate, an antiskid pavement layer is arranged on the upper surface of the rigid support plate, and a reinforcement layer is disposed on the lower surface of the rigid support plate to enhance the rigidity of the rigid support plate in the driving direction, and an elastic buffer layer is arranged under the reinforcement layer.
