| abstract |
The present invention relates to a bituminous binder comprising bitumen and at least two additives, which can lower the preparation temperature, the processing temperature and the compression temperature of the mixture, and can lower the production temperature and the processing temperature of the asphalt. In this regard, the first additive is a Tall Oil derivative, in the form of a single substance or in the form of a mixture, and the second additive is a monoester of a fatty acid mixture. The invention also relates to a low temperature process for the preparation of asphalt and mixtures obtained in binders comprising additives. Finally, the present invention provides the use of binders containing additives and sub-base courses, base courses, foundation courses, binder courses to produce mixtures and asphalt at low temperatures. It relates to the use of mixtures or asphalt in road applications in surface courses such as) and / or wear courses. |
