Abstract:
To invent special soil stabilizer used in cold areas, the chemical analysis method was utilized to find out high polyacrylamide(PAM)with surface activity that is the major component of the PAMCATS soil stabilizer. On the other hand, the aluminum saline and lime also are added as the auxiliary component of it. This paper analyzes the reactions of PAM, soil, lime and aluminum saline, at the same time, the reaction of lime and soil is also studied. Subsequently, a series of indoor tests and trial-sections are carried out to study the solidifying strength, water stabilization, frost durability, CBR, modulus of resilience. The results show that the solidification soil adding PAMCATS soil stabilizer is perfect in solidifying strength, water stabilization, frost durability and performances in subgrade. 4 tabs, 9 figs, 9 refs.
