Title:
EXTRACTION SOLVENT COMPOSITION, EXTRACTION METHOD, AND TEST METHOD
Document Type and Number:
WIPO Patent Application WO/2017/179582
Kind Code:
A1
Abstract:
Provided are: an extraction solvent composition having an equivalent asphalt extraction capability to trichloroethylene and allowing for an effective and safe extraction operation; an asphalt extraction method using the extraction solvent composition; and a paving material test method allowing for an effective and safe extraction operation using the extraction solvent composition. The extraction solvent composition contains 65% by mass or more of trans-1,2-dichloroethylene with respect to the total amount of the extraction solvent composition, and is for extracting asphalt from a mixture containing an aggregate and asphalt. The paving material test method comprises steps of: using the extraction solvent composition and subjecting the paving material containing the aggregate and the asphalt to extraction processing; measuring the remaining mass of the paving material wherefrom the asphalt-containing extraction component has been removed by the extraction processing, thereby measuring the contained amount of the asphalt-containing extraction component in the paving material; and assessing whether or not the contained amount of the obtained asphalt-containing extraction component falls within a predetermined contained amount range.
