ABSTRACT:
Abstract not available for EP0370017
Abstract of corresponding document: WO8808866
Process for preparing a modifier for bitumen, consisting of: mixing a
socalled ''lubricating fraction'' composed of lubricating liquids
derived from oil or synthetic products with polymers or polymer
mixtures which can be attacked by the ''lubricating fraction'' and with
other additives such as atactic ehylene-propylene copolymers,
polyolefins, polystirene, polydiene; melting said solid components to
make them homogeneous to one another; casting said components in
cake-shaped moulds or reducing them to grains; cooling said mixture to
room temperature. The obtained product is a modifier to be successively
added to bitumen in order to provide impermeable sheaths or other
impregnating products, conglomerates or featheredges.
