Abstract:

CTMAB is a new organic cationic surfactant. A chemical improved experiment is based on CTMAB towards to the natural expansive soil; and the improved mechanism and effect are studied. The result shows that the plasticity and expansibility of stabilized expansive soil decrease significantly compared with plain soil; and its water stability increases obviously. Soil samples remain enough strength after repeated dessolution different times, which indicates that CTMAB can effectly improve the engineering properties of expansive soil. The achievement patent has been authorized.

Key words: expansive soil, CTMAB improver, experimental study
