1-Alkyl-1,1-Dimethylhydrazinium Chlorides as Modifiers of Oil Asphalts for Road Building Applications

摘要

Aklylation of 1,1-dimethylhydrazine with higher alkyl chlorides was studied. The resulting 1-alkyl-1,1-dimethylhydrazinium chlorides were tested as modifiers of oil asphalt for preparation of asphalt concrete.
