The invention relates to granular bitumen that is solid at ambient temperature, including a core and a coating layer that covers all or part of the surface of the core, wherein the core includes at least one bitumen base, and the coating layer includes at least one viscosifying compound and at least one anticaking compound. The invention also relates to a method for manufacturing bitumen that is solid at ambient temperature and to the use of bitumen that is solid at ambient temperature as a road binder, particularly for manufacturing asphalts. The invention moreover relates to a method for manufacturing asphalts from solid bitumen and to a method for transporting and/or storing road bitumen that is solid at ambient temperature. 本发明涉及在环境温度下是固体的粒状沥青，其包含核和覆盖全部或部分的核表面的涂层，其中所述核包含至少种沥青基质，所述涂层包含至少种增黏化合物和至少种抗团聚化合物。本发明还涉及种制造在环境温度下是固体的沥青的方法，还涉及在环境温度下是固体的沥青作为道路结合料的用途，特别是用于制造沥青混合料的用途。本发明还涉及由固体沥青制造沥青混合料的方法，还涉及运输和/或储存在环境温度下是固体的道路沥青的方法。
