THE ASPHALT CONCRETE MANUFACTURE METHOD OF HAVING USED REPRODUCTION AGGREGATE AND THIS USING REPRODUCTION AGGREGATE AND WASTE CEMENT

摘要

The present invention mixes a small amount of new materials such as cement, fly ash, lime and the like in the waste cement and fine powder obtained in the process of manufacturing recycled aggregates from recycled aggregates, such as waste concrete, by coating the surface of the recycled aggregates , Recycled waste cement and fines are easily recycled. Also, recycled aggregate coated with cement has excellent ionic bond with asphalt, so that it is possible to produce high quality asphalt concrete using recycled aggregate, waste cement and fine powder. The purpose of the present invention is to provide a cement-coated mixed aggregate using recycled aggregate and waste cement, and an asphalt concrete manufacturing method using the same.;Cement-coated mixed aggregate using recycled aggregate and waste cement according to the present invention for achieving the above object is a recycled coarse aggregate and recycled fine aggregate and crushed waste concrete at the same size; Mixed with the recycled coarse aggregate and the reclaimed coarse aggregate, and the waste cement and fine powder separated and extracted in the production process of the regenerated coarse aggregate and regenerated coarse aggregate; The recycled coarse aggregate and recycled fine aggregate and waste cement and fine particles are mixed with cement, fly ash, characterized in that consisting of a new material consisting of lime.;In addition, the asphalt concrete manufacturing method using a cement-coated mixed aggregate according to the present invention for achieving the above object is to crush the waste concrete to a suitable size over several times, such as by crushing the waste concrete, and after filtering the crushed residual particles to the screen, Washing with water or separating into a separation facility to produce recycled coarse aggregate and recycled fine aggregate; Preparing a cement-coated wet aggregate by mixing a small amount of new material with the waste cement and the fine powder obtained in the manufacturing process of the recycled coarse aggregate and the regenerated coarse aggregate into a mixer; Preparing a cement-coated mixed aggregate by curing the cement-coated wet aggregate for a predetermined time; The cement-coated mixed aggregate and a predetermined amount of asphalt is put into an asphalt plant, characterized in that the step of producing asphalt concrete by mixing.
