Abstract
La présente invention décrit un diluant comprenant : (a) un éther avec entre 2 et 8 atomes de carbone et (b) un hydrocarbure non polaire avec entre 2 et 30 atomes de carbone. Le diluant sert à diluer les hydrocarbures visqueux, comme le bitume. À titre d'exemple, le diluant peut être de l'éther diméthylique et du propane. La dilution peut se faire in situ ou à la surface.
