ABSTRACT:
Described is the use, for preparing or treating bituminous compositions, of at least one compound selected among: esters of glycolic, lactic and gluconic acids, methylic, ethylic and isobutylic esters of glutaric, succinic and adipic acids, and ethers or esters of a product resulting from internal dehydration of a sugar, preferably a hydrogenated sugar. Also described is a method for preparing or treating such compositions and the resulting compositions.
