Abson Recovery Method Asphalt Rotovapor Apparatus
**Abson Recovery Method Asphalt Rotovapor Apparatus**
This test method outlines the procedure for recovering asphalt from a solution obtained through a prior extraction using the Abson method. The process ensures that the recovered asphalt retains properties similar to those it had in the original bituminous mixture, and in quantities sufficient for further testing.
The apparatus is designed to efficiently recover asphalt while maintaining its integrity and chemical composition. It includes a variety of components specifically selected to support the recovery process, ensuring accuracy and reliability.
