Abstract

The vast potential of geotextiles for separation (reinforcement in pavements and rail roads is yet to be fully exploited in India, despite the initial successful trials. This is partly due to the lack of sufficient test data on the behavior under repetitive loading of indigenous geotextiles. This paper reports typical triaxial test results on reinforced and unreinforced specimens before and after cyclic loading. The reinforcement used is a needle punched polypropylene geotextile manufactured in India. The results reported include strength before and after cyclic loading (cyclic loading under both drained and undrained conditions), modulus of resilience and plastic strain. Limited test results on simulated rail road (pavement) specimens clearly reveal the absence of intermixing and improvement in strength and hence possible rutting.

Behavior of Geotextile Reinforced Soil under Cyclic Loading

St. Louis, Missouri

The vast potential of geotextiles for separation (reinforcement in pavements and rail roads is yet to be fully exploited in India, despite the initial successful trials. This is partly due to the lack of sufficient test data on the behavior under repetitive loading of indigenous geotextiles. This paper reports typical triaxial test results on reinforced and unreinforced specimens before and after cyclic loading. The reinforcement used is a needle punched polypropylene geotextile manufactured in India. The results reported include strength before and after cyclic loading (cyclic loading under both drained and undrained conditions), modulus of resilience and plastic strain. Limited test results on simulated rail road (pavement) specimens clearly reveal the absence of intermixing and improvement in strength and hence possible rutting.
