| description | The invention discloses a PFWD detection-based digital-analog pavement in-situ cold-recycling construction method, and relates to the technical field of road engineering. The PFWD detection method is adopted to comprehensively evaluate an old cement concrete pavement, data of a plurality of performance indexes are obtained, and the correlation of the bearing performance indexes is established based on the data; the condition of the old pavement can be known more accurately, a basis is provided for subsequent rubblization transformation, finite element numerical simulation is carried out by establishing a numerical model, mechanical response analysis is carried out on the pavement after rubblization transformation, and the pavement structure performance under different conditions is evaluated. Meanwhile, mechanical parameters of different materials are analyzed, a reclaimed material mix proportion design method is determined, reclaimed material and rubblization technologies are adopted, old cement concrete res |
