    摘要: The invention relates to a coated granulate for coating roads that comprises i) a mineral granulate and ii) a non-bituminous binder obtained from raw materials of vegetable origin. The binder comprises a cellulose compound of the cellulose fatty-ester family. The melting temperature of the cellulose compound is advantageously 60°C to 250°C, preferably 120°C to 180°C. The coated granulate may include 1% to 20% of the binder in weight percent relative to the material, preferably 4% to 10%. The invention also relates to a method for preparing a coated granulate using said binder.
