Relationships of flow properties to chemical composition for paving asphalts
Rheological properties and chemical compositions were determined for nine paving-grade asphalts; flow properties at 45,77, and 120 F were obtained by means of sliding-plate microviscometer; modified Corbett-Swarbrick chromatographic method for chemical composition data was employed; multiple-linear-regression analysis yielded equations that related flow properties at 120 F to chemical composition; regression equations were obtained for flow properties at 45 and 77 F, and for Walther viscosity-temperature slope.
