Title:
再生アスファルト混合物の製造方法及び試験ユニット
Document Type and Number:
Japanese Patent JP7443611
Kind Code:
B2
Abstract:
This asphalt mix regeneration method comprises: an analysis step of analyzing an effective asphalt component content ratio in an asphalt mix waste material; a determination step of determining, on the basis of the effective asphalt content ratio obtained in the analysis step, the quantity of additive needed for regenerating the waste material; an introduction step of introducing into a container the waste material, and the additive in the quantity determined by the determination step; and a stir-heating step of decreasing to pebble-scale the sizes of the waste material and the additive that have been introduced into the container, while holding the internal temperature of the container in a temperature region of 170°C to 200°C through heating, and mixing together the waste material and the additive to produce a regenerated asphalt material.
