Abstract
In order to develop a smart city, the role of smart transportation infrastructure system is essential, which will improve the ability to connect and improve the quality of human being by saving time and energy. In the present paper, an attempt has been made to improve the soil for the construction of smart structures. In the present paper, the aim is to study the variation of load carrying capacity and shear parameters of soil after introducing granular columns of varying diameter. Results show that the granular columns derive the strength from the soil confining them. The granular columns also help in easy drainage and reduction in pore pressure. A series of CBR and direct shear test were performed after the installation of granular columns at the centre of the specimen by varying the diameter in the soil where it was found that there was an improvement in load carrying capacity and shear strength parameters of the soil. The study also presents swelling behaviour of soil against time.
