COMPOSITIONS BITUMINEUSES THERMORETICULEES COMPRENANT DES PARTICULES D'ARGILE, PROCEDES ET UTILISATIONS ASSOCIES
The invention relates to bituminous compositions comprising: - a matrix formed by thermal cross-linking of a mixture comprising: *a bitumen base, *a thermally cross-linkable elastomer, chosen among the thermally cross-linkable block copolymers of formula S-B-S, also called thermally cross-linkable SBS elastomers, in which each S independently represents a block made of aromatic monovinyl hydrocarbon monomers, B represents a block made of butadiene monomers, the block B comprising pendant vinyl groups, and in which the blocks S represent, together, at least 15% by moles of the total number of moles of monomer units of the thermally cross-linkable block copolymer, the thermally cross-linkable block copolymers having a weight average molecular mass ranging from 40,000 to 500,000 g/mol and having a pendant vinyl group content greater than or equal to 20% by moles, with respect to the total number of moles of thermally cross-linkable block copolymer monomer units, and *an olefinic polymer adjuvant functionalised with epoxide groups, and in particular with glycidyl groups, - clay particles distributed in the matrix. The invention also relates to a method for preparing such compositions, as well as their use in the road-construction and industrial fields.
