Abstract
A binder composition includes at least: a binder base selected among an oil, a bitumen base, a pitch, a clear binder, or mixtures thereof; an acid compound of general formula (I): R—(COOH)z (I); an amide compound of general formula (II): R′—(NH)nCONH—(X)m—(NHCO)p(NH)n—R″ (II), the compounds of formula (I) and formula (II) being provided in a weight ratio of 10:1 to 1:16. A process for manufacturing bituminous mixes including at least the binder composition and aggregates, includes at least the steps of: heating the aggregates to a temperature ranging from 100° C. to 180° C., mixing the aggregates with the binder composition, and obtaining bituminous mixes. A method for transporting and/or storing and/or handling the binder composition includes transporting and/or storing and/or handling the binder composition in the form of blocks or pellets.
