METHOD FOR MANUFACTURING HIGH STRENGTH AGENTS FOR ASPHALT-CONCRETE AND METHOD FOR MANUFACTURING ASPHALT-CONCRETE USING HIGH STRENGTH AGENTS

摘要

Disclosed are a method for manufacturing a high-strength agent for asphalt-concrete and a method for manufacturing asphalt-concrete using the high-strength agent for asphalt-concrete. The method for manufacturing a high-strength agent for asphalt-concrete according to the present invention comprises the steps of: pulverizing regenerated EPDM into a size of 3 mm or smaller; mixing 100 parts by weight of one resin selected from SBS and SIS with 40 to 150 parts by weight of process oil and maturing the resin for three hours or longer; and mixing 100 parts by weight of HDPE with 30 to 80 parts by weight of a petroleum resin and pulverizing the HDPE into a size of 3 mm or smaller by heating the mixture to 100-200 C, and extruding and cooling the mixture; and measuring and mixing the regenerated EPDM, the mixture of the resin selected from SBS and SIS with the process oil, and the mixture of the HDPE with the petroleum resin.
