Based on bituminous centesimal formula centesimal aggregates to recycle connections and structures driving applied with these tablets

摘要

The present invention aims to provide a new blacktop material comprising aggregates coated (ea) and an adjuvant of rejuvenation, this additive allowing remobilization of the recycled bitumen such that the coated material is brought as close as possible, or even equal to, the technical characteristics of the coated with bitumen nine. To do this, the coated product is characterized in that the adjuvant includes: a mixture comprising a. 5 to 30% by weight of fatty acids of tall oil (tall oil), preferably 10 to 25%, b 1 to 35% by weight of tall oil fatty acids esterified, preferably 5 to 30%, c. 10 to 30% by weight of resin acids, preferably 15 to 25%, optionally one or more substance (s) selected (s) from among the polymers, the binders, the fluxes, the oleoresinous, the hydrated lime, the spreading agents and of adhesion and mixtures thereof, and possibly water, said additive, representing, in dry material, at least 10% by weight of the bitumen contained in the ae, preferably at least 20%. The present invention also relates to the process of production of the coated, the adjuvant of rejuvenation by - the same way, a bituminous binder comprising such an additive, the use of the additive in a composition of bituminous coated material, and a method of implementation of a road structure using the bituminous mix.
