ABSTRACT
This chapter presents the results of the effect of remolding methods on soil swell pressure, unconfined compressive strength, and swell potential of three types of undisturbed and disturbed soil samples. Disturbed soil specimens were prepared using dynamic remolding, static remolding, and kneading remolding. Swell potential, swelling pressure, and unconfined compression tests were conducted on identical samples remolded by different methods having similar initial conditions to the undisturbed samples. Another set of experiments was also conducted to examine the influence of initial water content on soil swell pressure and unconfined compressive strength under different remolding techniques. Results indicated that the undisturbed samples have the highest swell pressure and swell potential values followed by dynamic remolding, while kneading remolding gave the lowest values for the three types of soil. For the same types of soils, it has been found that the swell pressures of the undisturbed samples were a factor of 1.5, 1.96, and 3.07 higher than that for the dynamic, static, and kneading remolding, respectively. Similar trends were obtained with regard to unconfined compressive strength and swell potential. The unconfined compressive strengths of the undisturbed samples were a factor of 1.35, 1.6, and 2.53 higher than soil strength obtained by dynamic, static, and kneading remolding, respectively.
