Pavement joint overlapping structure and construction method thereof

The invention discloses a pavement joint overlapping structure and a construction method thereof. The overlapping structure comprises a new road structure and an old road structure, and the road surface elevation of the new road structure is higher than that of the old road structure. The new road structure comprises: a base layer, wherein the base layer is laid on the old road structure, the overlapping end of the base layer is cut off at the position of a first compaction thickness section, and a virtual pinching triangular area is formed between the first compaction thickness section and the upper surface of the old road structure; and a surface layer paved on the base layer, wherein the pinching triangular area is filled with the surface layer, the overlapping end of the surface layerand the old road structure extends into the old road structure, and the upper surface of the surface layer is smoothly overlapped with the upper surface of the old road structure. According to the overlapping structure, a ste
