Method of obtaining a bituminous binder, bituminous binder and application of the binder obtained.

摘要

The present invention relates to a process for obtaining a bituminous binder for the production of a surface coating on a roadway, which consists in preparing a stock solution - based on elastomer and bitumen selected or of a heavy petroleum oil or a mixture of bitumen selected and of heavy petroleum oil or a mixture of bitumen and heavy petroleum oil, to dilute the mother solution - with a plasticizer which is not volatile oil or a heavy oil or petroleum or carbochemical a fluidizing agent, or mixtures thereof, in order to lower the viscosity, in mixing the product obtained with a road asphalt and to carry out the fluxing of the mixture with a diluent, a petroleum or fluxing carbochemical, or a cutback bitumen in the quantity required to obtain the desired viscosity for the spreading.
