REGENERATION METHOD AND REGENERATION DEVICE OF WASTE ASCON FOR ASPHALT BASE LAYER

摘要

PURPOSE: A method and an apparatus for renewal of waste ash concrete are provided to achieve a mass regeneration of a high quality concrete. CONSTITUTION: A method comprises a first step of crushing waste ash concrete into a predetermined thickness, a second step of feeing the crushed waste ash concrete into a first hopper and new aggregate to be mixed with the waste ash concrete into a second hopper, a third step of extracting a predetermined amount of the waste ash concrete and new aggregate fed into the first and second hoppers, injecting the extracted waste ash concrete and new aggregate into a drum, mixing the injected material, and heating the mixture at a predetermined temperature, a fourth step of regenerating asphalt by adding an asphalt oil to the mixture discharged from the drum and mixing the resultant, and a fifth step of storing the regenerated asphalt to a storage hopper.
