Cross Section of the Geotextile Reinforced Road along MDR 82
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.
