Fremgangsmåte for fremstilling av en granulometrisk blanding som er koldomhyllet med en bitumenös emulsjon |
摘要 |
Storable dense coated mixes and emulsion-gravels are produced by coating with a mixed emulsion of hard bitumen and soft bitumen. Unexpectedly, these coated mixes have a storability which makes them resemble coated mixes produced with a soft bitumen, but they assume the cohesion which corresponds to the viscosity of the bitumen consisting of the homogeneous mixture of bitumens. The mixed emulsion, preferably cationic, is produced very simply, for example by mixing an emulsion of hard bitumen and an emulsion of soft bitumen. <IMAGE> |
