RECONSTITUTED ASPHALT PAVING COMPOSITIONS

摘要

Asphaltic compositions suitable for use in paving formulations and having desirable viscosity, temperature susceptibility and ductility properties can be made by combining propane precipitated asphalt, asphaltenes and a liquid petroleum derivative such as a heavy distillate or residual oil. These compositions allow maximum utilization of low cost asphaltenes and produce compositions having improved viscosity and temperature susceptibility properties.
