Abstract

Black cotton soil also known as expansive soil poses a lot of problems to structures resting
over it. Flexible pavements with expansive soil subgrade have shown very poor performance due to
differential settlement and cracking. The present study deals with the cost effectiveness of flexible pavement
on stabilized expansive soil. The subgrade course was stabilized with lime and California Bearing Ratio
(CBR) test was performed for different proportions of lime content. The thickness of various layers of
pavement was then calculated in accordance with IRC: 37 [1]. Cost analysis was then made for pavements
with both unstabilized and stabilized subgrade course based on Public Works Department (PWD) of Delhi. It
was observed that when expansive soil was stabilized with 5% lime content, the drop in cost of flexible
pavement was maximum.
