The process comprises incorporating a predetermined quantity (50 wt.%) of hydrocarbonated binder to an assembly of granular mixture in a mixer (1), humid mixing for forming a sealant, and incorporating the rest quantity of hydrocarbonated binder in the mixer and then mixing. The coating comprises a predetermined quantity of hydrocarbonated binder and a granular mixture comprising fine elements (2) and thick granulates (3) such as loose chippings, gravels and/or sands. The granular mixture comprises coating aggregates. The coating is a high modulus asphalt concrete. The process comprises incorporating a predetermined quantity (50 wt.%) of hydrocarbonated binder to an assembly of granular mixture in a mixer (1), humid mixing for forming a sealant, and incorporating the rest quantity of hydrocarbonated binder in the mixer and then mixing. The coating comprises a predetermined quantity of hydrocarbonated binder and a granular mixture comprising fine elements (2) and thick granulates (3) such as loose chippings, gravels and/or sands. The granular mixture comprises coating aggregates. The coating is: a high modulus asphalt concrete comprising fine limestone filler (1-5 wt.%), 90-95 wt.% of granulates of class 0/10, and 4.9-5.25 wt.% of pure bitumen of class 20/30; a high modulus coating comprising fine limestone filler (1-5 wt.%), 90-95 wt.% of granulates of class 0/14, and 5-5.3 wt.% of pure bitumen of class 10/20; and a thin asphalt concrete comprising fine limestone filler (1-5 wt.%), 90-95 wt.% of granulates of class 0/10, and 4.6-4.9 wt.% of polymer bitumen. An independent claim is included for a coating having a reduced content of hydrocarbonated binder. |
