ANALYSIS OF ASPHALT The rubber content in a low gel rubber modified asphalt may be accurately and rapidly determined using gel permeation chromatography in which one or more columnscomprise glass particles having a size from 801120 mesh to 200/400 mesh and a pore size from 75 to 120A. The analysis may be automated and is faster and more accurate than currently used procedures. |
