Abstract

Process for the rejuvenation of asphalts contained in old surfacing agglomerates, using a polymer bitumen having a high polymer concentration of the synthetic elastomer type formed by one or more synthetic elastomeric polymers, modifying this through the addition of free sulphur or any component capable of releasing sulphur under the effect of heat, stabilizing through the addition of fatty acid(s), which may contain polyamines as bonding agent, having application in a regeneration process using hot "in-situ" recycling techniques or in a fixed plant for the production of agglomerates.
