PROCÉDÉ DE FABRICATION D'UNE COUCHE DE REVÊTEMENT ROUTIER À BASE D'ENROBÉ HYDROCARBONÉ À FROID
The invention relates to a method for producing a road surface layer based on a hydrocarbon cold mix, the method comprising the following steps: a) coating at room temperature in a mixer of a self-propelled machine a mineral solid fraction with a cationic hydrocarbon binder emulsion, water being added to the mixer to make the total water content thereof between 8 ppc and 14 ppc relative to the dry solid mineral fraction to form a hydrocarbon cold mix in which the typical content of the residual anhydrous binder, as described in standard NF P 98-139:2016-12, varies from 3.5 to 6% relative to the weight of the mix after drying; b) applying the hydrocarbon cold mix directly at the output of the mixer of the self-propelled machine to form a layer having a thickness of at least 2 cm; and subsequently c) compacting the layer applied in step b) to form the road surface layer.
