Inclusion Of Geosynthetics As A Basally Reinforcement Into Base-Course Over Soft Soil

Abstract

Wheels of vehicles at surface of pavement will pass through it lot of times. Therefore, pavement or base course over soft soil always needs reinforcement. Inclusion of geosyntheticsinto base-course as basally reinforcement and influence of a repeated loading are presented. Several existing methods such as Giroud-Han, USA Corps of Engineers and DuPont Typar method to calculate thickness of base course over soft soil using reinforcement material either geotextile or geogrid are presented and the influence of a repeated load will be compared. Results from calculation and analysis indicate that Giroud-Han method gives thickness of base course higher than other methods when CBR values of subgrade at least 2 %.
