AN ISOLATING LAYER OF LARGE-SPACE JOINT REINFORCED CEMENT CONCRETE PAVEMENT AND CONSTRUCTION METHOD AND APPLICATION THEREOF
The invention belongs to the technical field of road engineering, in particular to an isolating layer of large-space joint reinforced cement concrete pavement and construction method and application thereof. The invention provides an isolating layer of large-space joint 5 reinforced cement concrete pavement. The isolating layer comprises a waterproof layer, a coarse sand layer and a PET film layer overlapped sequentially. The isolating layer of large-space joint reinforced cement concrete pavement in the invention has the advantages of being excellent in water resistance and capable of effectively improving the load distribution and the expansion stress of cement concrete panel under the vehicle and temperature load, 10 reducing the friction coefficient and shearing strength between concrete panel and base course and minimizing the bonding strength between base course and cement concrete pavement. Vehicle load Temperat ure effect Figure 1 Figure 2 Figure 3
