OXIDANT-MODIFIED BITUMINOUS BINDER COMPOSITION

摘要

The invention relates to a process for preparing a bituminous binder composition for making layers and/or coatings for road construction and/or civil engineering without air blowing, comprising mixing a bituminous binder comprising an initial bitumen and at least one oxidizing agent, and obtaining a bituminous binder composition comprising a final bitumen that is applied in order to form a layer or coating for road construction and/or civil engineering. The invention also relates to the use of at least one oxidizing agent for improving the resistance to permanent deformation of a bituminous binder as well as permanent deformation of asphalt mix using such bituminous binder.
