Patent

CA 2256045

Use is made, as thinner or fluxing oil in an anhydrous or emulsified bituminous binder, of methyl esters of fatty acids which are obtained in particular by transesterification of vegetable oils. The hardening of the binder after spreading is obtained no longer by evaporation but by crosslinking of the thinner in the presence of atmospheric oxygen and of a catalyst. The problems of pollution and of safety brought about by the evaporation of thinners of petroleum or carbon chemistry origin are thus avoided.
