چکیده:

Soil improvement is referred to evolve physical and engineering characteristics of soil. Recently, new chemicals like polymers are used to speed the operation of soil improvement and ease the access instead old soil stabilizers such as cement, lime and etc. there are not so many information, however, about operation of these materials within the soil. This study attempts to give more information about these soil stabilizers and to show their affects within the soli. In this study, effects of two polymers namely PET and UF are studied in improvement of a problematic sandy soil. In which it is resulted that with usage of PET and UF resins CBR value increased by 713% and 677% in dry state, and increased by 1044% and 750% in saturated state, respectively
