The invention discloses a new and old
asphalt pavement
lap joint structure, and relates to the technical field of
urban road traffic engineering construction.The new and old
asphalt pavement
lap joint structure comprises an old pavement, a new pavement is arranged on one side of the old pavement, and a connecting
assembly is arranged between the old pavement and the new pavement; the connecting
assembly comprises an inverted triangular
pyramid soft inserting block, the inverted triangular
pyramid soft inserting block is inserted between the old
road surface and the new
road surface, a fixed inserting needle is arranged on the inverted triangular
pyramid soft inserting block, the fixed inserting needle is arranged on the side face of the inverted triangular pyramid soft inserting block, and a pressing soft plate is arranged on the inverted triangular pyramid soft inserting block; the two ends of the press-fit soft plate are connected with the end face corner angles of the old pavement and the new pavement respectively, and an anti-
cracking soft plate is arranged on the upper portion of the press-fit plate. Due to the design of the inner inverted triangular pyramid soft
insertion block, the inner inverted triangular pyramid soft
insertion block can be tightly inserted into a gap between an old pavement and a new pavement, the gap is effectively sealed, the integrity and stability of the pavement structure are enhanced, and meanwhile, due to the arrangement of the expansion piece, the connection between the new pavement and the old pavement is firmer through filling and expansion of expansion glue.
