Geosynthetic Properties and Testing

General Properties (commonly given in sales brochures) 

Geosynthetics have been used in new road construction in various ways to minimise the previousiy mentioned probiems as weii as in the maintenance of existing paved roads (overiays appiied to strengthen existing pavements). In this category of application the two principal roles for geosynthetics are separation/filtration, and reinforcement. The use of geosynthetics to perform these functions in unpaved and paved roads is discussed in Section 5.1.3.1 and 5.1.3.2. 

For asphalt pavement reinforcement, stiff extruded geogrids are the best option and the best locations are [7]  

Use of geosynthetics for taxiways, runways and car parks follows the same principles as for paved roads. 

Railways tracks are supported by granular material called ballast . The application of geosynthetics in railways is therefore somewhat similar to unpaved roads and can be considered basically in two categories
