Geosynthetics in roads and pavements

 

Geosynthetic Solutions 

Geosynthetic solutions include geotextiles, 

geogrids and combinations of geotextiles and 

geogrids. While a wide variety of site 

improvement methods have been used during 

the past decade, soil reinforcement has emerged 

as an efficient, economical and effective 

solution to the problem of constructing 

embankments over soft soils. 

 

 

Reinforced Embankment Concept 

 

Geotextiles 

For many years very strong fabrics have been 

employed in constructing embankments over 

soft ground. Very strong fabrics, with tensile 

strengths ranging from 1000 lb/in to 4500 lb/in, 

are placed over a prepared ground surface and 

earthen embankments are erected using a system 

of controlled height lifts to maintain uniform 

pressure on the subgrade.
