METHOD FOR MANUFACTURING ASPHALT CONCRETE CONTAINING MICROPARTICLE MINERAL POWDER

摘要

The present invention relates to a method for manufacturing asphalt concrete containing microparticle mineral powder and, more specifically, to a method for manufacturing asphalt concrete containing microparticle mineral powder including: a material preparation step composed of a step of storing aggregates in a designated cold bin of a manufacturing process line according to a size, a step of storing asphalt in a designated oil tank of the manufacturing process line, and a step of collecting microparticle mineral powder and thereafter storing the collected microparticle mineral powder in a silo of the manufacturing process line; a step of transferring the materials prepared in the material preparation step to a mixing means by using each designated means; an asphalt concrete manufacturing step of mixing and stirring the materials transferred to the mixing means in the transferring step at a preset rate; and a step of shipping the asphalt concrete manufactured in the manufacturing step by a preset unit in bulk or in a packing type. The method for manufacturing asphalt concrete containing microparticle mineral powder is capable of providing an improved aggregate costing effect in comparison with existing asphalt concrete, saving manufacture cost by reducing the content of asphalt, improving resistance to plastic deformation, preventing the degradation of asphalt, and improving the durability of the packed product by providing excellent mobility resistance.;COPYRIGHT KIPO 2016
