Abstract

The invention relates to the technical field of pavement maintenance, and relates to a method for repairing a pavement by using plain concrete and reinforced concrete. The method for repairing the pavement comprises the following steps: removing and arranging the disease area of the pavement, compacting an original roadbed, excavating a C15 concrete road trough in the thickness range of the original roadbed, pouring C15 plain concrete to the C15 concrete road trough, arranging a C20 concrete road trough on the top surface of the C15 plain concrete, pouring C20 plain concrete into the C20 roadtrough, laying an asphalt sealing oil layer on the C20 concrete plain concrete, pouring a concrete pavement board with a reinforcement mat arranged at the bottom layer onto the asphalt sealing oil layer, laying an asphalt viscous oil layer on the concrete pavement board, arranging a stress absorbing layer on the asphalt viscous oil layer, and laying asphalt concrete on the stress absorbing layer.The method has the characteristics of effectiveness in repairing the disease pavement area, and realization of stable structure, good pressure resistance and good subsidence resistance of a repaired place.

Description

technical field [0001] The invention relates to the technical field of road surface maintenance, in particular to a method for repairing road surfaces by using plain concrete and reinforced concrete. Background technique [0002] At present, most roads in our country are paved with asphalt as raw material. Due to the rolling and friction of automobile tires and other vehicles, asphalt pavement damage often occurs on the road. The traffic of automobiles and pedestrians on the road brings great inconvenience, and this way wastes energy greatly, and there is also the problem of high labor intensity of workers. [0003] For urban asphalt pavement maintenance, the traditional design scheme is to restore according to the original road design scheme. Conventional asphalt pavement design generally adopts the method of flexible subbase (graded gravel) + semi-rigid base (cement stabilized gravel) + asphalt surface. The flexible subbase and semi-rigid base need layered rolling constr...
