ABSTRACT:
Methods are disclosed for preparation of chemically-stabilized emulsions of tall oil in water. Temperature and pH are controlled during preparation of the emulsions so as to prevent saponification and neutralization of acids in the tall oil component. The final emulsions have pHs in the range of from about 3.0 to 5.0 and remain phase stable for extended periods of time. Methods are disclosed for using the emulsions for soil treatment to improve soil stabilization and load bearing capacity for roadbed use, for treatment of reclaimed asphalt pavement for reuse as a stabilized base course for roadway construction and for remediation of heavy metal contaminated soil.
