Bitumens modified with polymer compositions containing polyethylene, (co)polymers of ethylene with propylene and/or polypropylene, which are virgin or recycled after use

摘要

Bitumens modified by polymer compositions containing polyethylene (PE), (co)polymers of ethylene with propylene (EPM or EPDM) and/or amorphous polypropylene (PP) show improved performance with respect to bitumen as such or bitumen modified with conventional polymers and with respect to bitumen modified with PE alone, on account of their special structural and morphological properties.
