Abstract
The invention provides a method comprising 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 pre-formed, 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.
