Hot in-place asphalt recycling apparatus and road paving method using same

摘要

The present invention relates to a hot in-place asphalt recycling apparatus and a road paving method using same. To this end, the hot in-place asphalt recycling apparatus provided with a preheater part and a recycling part, according to the present invention, is characterized in that: the preheater part comprises a support frame on one side, having driving wheels connected to a driving part, a fuel supply part having a fuel tank above the support frame on one side, and an ignition nozzle part provided below the support frame on one side, wherein fuel supplied from the fuel supply part to the ignition nozzle part is ignited so that an asphalt road surface is heated and softened; and the recycling part comprises a support frame on the other side, having driven wheels, a recycling tank provided above the support frame on the other side and to which a recycling additive is inputted, and a road surface removal part provided below the support frame on the other side located at the lower part of a side of the recycling tank, wherein the heated and softened road surface is scraped and fed into an inlet of the recycling tank so as to obtain recycled asphalt mixed with the recycling additive, and the recycled asphalt is outputted via an outlet provided on the other side of the recycling tank. Therefore, the present invention allows the heated and softened road surface to be scraped by the road surface removal part, thereby preventing aggregate inside the surface layer from which the road surface has been removed from breaking, while preventing a change in the gradation of the aggregate from occurring.
