چکیده مقاله
This paper presents the results of an experimental program developed to assess the effect of an ionic stabilizer branded as CBRPLus/CON AID on the swelling potential of an expansive soil collected from a forest road in the northern region of Iran A series of swelling tests consisting of free swelling and swelling pressure were conducted on natural and stabilized soil specimens in an Oedometer apparatus Results indicated that the use of various concentrations of the ionic stabilizer 0 0096%, 0 03%, 0 05%, 0 07% and 0 09% caused a considerable reduction in the swelling properties consisting of final free swell Sf and swelling pressure Ps Furthermore free swelling FSC and swelling pressure SPC curves fornatural and stabilized soil were modeled as a function of the ionic stabilizer concentration and its corresponding maximum dry unit weight using multivariable regression models In addition a simplified sensitivity analysis was adopted to investigate the effect of the ionic stabilizer concentration and its corresponding maximum dry unit weight on the final free swell and swelling pressure values of natural and stabilized soil specimens
