Introduction

Black Cotton Soil; CBR less than 2; High Water table. Traffic Intensity Medium. Commercial vehicles mainly carrying sand and Sugarcane ply on this route. Usually the road constructed in this section would not last for more than 6 months, developing severe rut depths and pot holes and would become almost unmotorable. The Geotextile (Techfab TPP 265) was placed between the sub base of Black Cotton soil, thus preventing the intermixing with the aggregate layer above. The Geotextile (Techfab TPP 265) would act as a reinforcing layer also and restrain the formation of rut depths.
