<p>The invention concerns a method consisting in contacting, between 100 °C and 230 °C and under agitation, an elastomer, a functionalising agent and optionally a peroxide compound. The functionalising agent is a thiolcarboxylic acid polyester or a reaction product of a thiolcarboxylic acid or ester with ethylene sulphide. The functionalised elastomer can also be preformed, then incorporated into the bitumen. The resulting compositions are usable directly or after dilution, for forming bituminous binders to produce surfacing, coating and waterproofing materials.</p> |
