The on-site heat regeneration technology for asphalt pavement is specially used for repairing the surface diseases of asphalt pavement, and mainly refers to a construction method of heating a pavement surface layer to a required depth, loosening an old pavement, adding a reducing or regenerating agent, and re-paving and molding. In situ thermal regeneration may be accomplished in a single operation, recombining the raw materials with the roadway to be repaired. Or by two stages, i.e. the regrind is recompacted and then a wearing course is laid on it. The existing asphalt pavement heating equipment can heat and further process the asphalt on the road, but the existing equipment still has some disadvantages.

The asphalt pavement heating plate disclosed in the chinese patent CN208792130U is characterized in that when a liquefied gas tank is fixed on a heating plate body, the liquefied gas tank is inserted into an insertion seat to position the liquefied gas tank, two arc-shaped fixing covers are rotated around their hinge points, the two arc-shaped fixing covers are fastened, and are connected and fixed by a connecting bolt and a connecting nut, so that the liquefied gas tank is fixed between the two arc-shaped fixing covers, and the liquefied gas tank is firmly fixed on the heating plate body, thereby preventing the liquefied gas tank from shaking due to impact vibration; through the arrangement of the buffer seat and the connecting spring and the buffer layer arranged on the inner wall of the arc-shaped fixing cover, the liquefied gas tank body is further protected in a buffering mode.
