BITUMINOUS BINDER FOR PREPARING LOW-TEMPERATURE ASPHALT OR COATED MATERIALS

摘要

The present disclosure relates to a bituminous binder including bitumen and at least two additives making it possible to reduce the manufacturing, processing and compacting temperatures of mixes and asphalts, the first additive being a Tall Oil derivative, alone or in a mixture, and the second additive being a monoester of a mixture of fatty acids. The disclosure also relates to low-temperature methods for the preparation of the mixes and asphalts obtained from the binder containing additives. The disclosure finally relates to the use of the binder containing additives in order to produce mixes and asphalts at lower temperatures, and the use of these mixes or asphalts, in particular in road applications, for sub-base courses, base courses, foundation courses, surface courses such as binder courses and/or wearing courses.
