Asphalt pavement hot in-place recycling layered heating method
The present invention discloses an asphalt pavement hot in-place recycling layered heating method comprising the following steps: a pavement recycled material harrowed by heating is collected and mixed with new asphalt to obtain a regenerated mixture; the regenerated mixture is first put into a heating mixing device for the first time heating mixing, and then sent to another heating mixing device for second time heating mixing, the heating mixing is repeated for multiple times until the regenerated mixture is heated from original 70-80 DEG Cto 140-160 DEG C; and the mixed heated regenerated mixture is directly discharged, and received by a followed pavement paver, and the regenerated mixture is paved on a recycled pavement, and finally is compacted by a road roller. The temperature of the regenerated mixture heated by the regenerated mixture layered heating method is raised to 140-160 DEG C, the final paving rolling temperature is enhanced; and asphalt smoke dust and a large quantity of heat generated by the heating are recycled, and waste flue gas is reused after recycling combustion.
