BITUMEN CUTBACK AGENTS

摘要

Bitumen cutback agents include esters, preferably methyl esters in the range C6 to C14, preferably C8 to C12. The methyl esters may be sourced from organic oils, such 5 as coconut or palm kernel oil. The cutback agent shows improved performance over prior cutback agents such as kerosene.
