Production of bitumen/crosslinked polymer binder composition, used as binder for road surfacing mixtures, involves stirring pre-epoxidated polymer and non-sulfurated crosslinker for polymer at high temperature

摘要

A method of preparing a bitumen/crosslinked epoxidated polymer composition involves contacting at 100-250 degrees C, with stirring, one or more bitumens, one or more pre-epoxidated polymers and a non-sulfurated crosslinker of the polymer.
