FLUXED BITUMINOUS BINDER, FLUXANT, PREPARATION AND APPLICATIONS OF THESE PRODUCTS

摘要

The invention concerns a bituminous binder comprising at least one bitumen B, at least one crosslinked or non-crosslinked polymer P and at least one fluxant F, characterized in that the fluxant F comprises at least one fraction derived from castor oil, said fraction comprising at least one methyl ester of fatty acid(s). The invention is also directed to the products incorporating this new fluxant F as an ingredient, particularly to bituminous compositions in the form of an anhydrous or emulsion binder, unmodified or modified with one or more polymers, in the presence or absence of one or more crosslinking agents. The invention further concerns a concentrated stock solution which is useful for the preparation of bituminous compositions of this kind.
