Abstract

a. L'invention concerne un procédé pour améliorer la résistance à la lixiviation des produits solidifés par le bitume obtenus en introduisant des déchets radioactifs dans du bitume liquide. b. On transforme les sels faisant partie de ces déchets qui ont tendance à former des cristaux hydratés en produits n'ayant pas cette tendance. c. Ce procédé permet d'augmenter considérablement la résistance des blocs solidifiés à une désagrégation qui serait causée par une absorption d'eau.at. The invention relates to a method for improving the resistance to leaching of products solidified by bitumen obtained by introducing radioactive waste into liquid bitumen. b. The salts forming part of this waste, which tend to form hydrated crystals, are transformed into products which do not have this tendency. vs. This process makes it possible to considerably increase the resistance of the solidified blocks to a disintegration which would be caused by water absorption.
