Asphalt having four types of heavy hydrocarbon component ratios, and a method for controlling the content ratio of the four types of heavy hydrocarbon components in the asphalt

摘要

The present invention relates to asphalt characterized by having a content ratio of four heavy hydrocarbon components consisting of 2.0 to 5.5 wt% of saturates, 45.0 to 65.5 wt% of aromatics, 14.0 to 25.0 wt% of resins, and 15.0 to 25.0 wt% of asphaltenes based on 100 wt%. According to the present invention, regardless of which raw material is used, it is possible to manufacture asphalt that satisfies quality standards required for asphalt, such as Pen No (penetration), ductility, and wax content ratio, by identifying various processes and optimal operating conditions and utilizing specific blends to satisfy the condition that each of the four hydrocarbon component ratios is included in a specific content ratio. That is, if the content ratio of each hydrocarbon type affecting the quality of asphalt is specified and the content ratio is satisfied, asphalt having a desired quality can be manufactured regardless of which crude oil is used as a raw material.
