ارزیابی خاک های تثبیت شده آسفالت فسفات برای کاربرد جاده ها

Results indicate that properly designed FSA mixes displayed a significant improvement in ITS (17% for marl and 9.4% for sand soils), Marshall stability (14% for marl and sand soils) and shear strength (135%, 76% and 250% for marl, sabkha and sand soils, respectively) as compared with those of conventional FA mixes. Resilient modulus testing indicated that FSA has marginally reduced the resilient modulus of soils compared with FA. Foamed sulfur asphalt technology can be used successfully to construct road bases from available marginal soils.
