UTILIZATION OF POLYMER-MODIFIED BITUMENS --BITUMEN, FLEXIBLE AND DURABLE. 3RD EUROBITUME SYMPOSIUM 1985, THE HAGUE, NETHERLANDS, SEPTEMBER 11-13, 1985

EMPLOI DE BITUMES MODIFIES PAR UNE ASSOCIATION DE POLYMERES

After ten years of observation of modified bitumens, whether in the laboratory or on roadways, it has become apparent that the use of certain clearly defined polymers, such as the sbs or eva families, in association with selected roadway quality bitumens, could provide asphaltic concretes with superior overlay characteristics and good fatigue strength. Likewise, binders used in the form of fluxed or emulsified bitumens, have given coatings capable of standing up to heavy, high-speed traffic (French motorway a6, for example). Between 1982 and 1984, we have developed second generation binders, where the association of a number of complementary polymers with the initially selected bitumens, has enabled US to produce asphaltic concretes suitable both for thin coat application on high traffic level roadways, and for use in heavy coat form (bitumen membrane using 3 kg binder per m2), crack bridging and maintenance coating functions being achieved with a single operation. This result has been obtained by substantial extension of the plasticity range and tensile elongation characteristics of the modified bitumen. This article describes studies made of binders of this type, together with observations recorded on a number of industrial sites, where such binders have been used for coating non-continuous microconcrete and asphaltic concrete structures in thin coat forms, as also sites where the asphaltic membrane technique has been employed.(a) for the covering abstract of the symposium see IRRD 815173.
