Scheme Design of Old Concrete Highway Subgrade and Pavement Reconstruction
In view of the poor reconstruction effect of the traditional reconstruction method of the old concrete highway,the road surface is prone to cracking,the optimization design is made based on the traditional method,and a new reconstruction method of subgrade and pavement is proposed.Taking the road reconstruction project in the core area of the Datang Lixiang Pastoral Complex in Gaozhou City as an example,calculate the old concrete road pavement structure of bending value,using Beckman Beam Deflection Meter detect the old concrete highway subgrade and pavement rebound deflection,design of concrete subgrade and pavement asphalt layer,selection with the old concrete highway the original base material in filling,the old and new concrete highway subgrade pavement splicing.After adop-ting the new design method for modification,the carrying capacity of the pavement structure is above 516.7 MPa,which proves that the carrying capacity of the pavement surface is improved after the transformation.
