Abstract

Geo-synthetics have been adopted in the reinforcement of the flexible pavements since last three decades.\nHowever, the performance of the road pavements can still be improved by characterization of different types of geo-synthetic\nused. Still, the performance of the roads they are used in, can still be increased with characterization of these materials. Geosynthetics\nhave been in practice due to the specific functional characteristics. They can modify stress distribution in road\npavements effectively. This paper thus focuses on the advantage of using geo-synthetics in flexile pavements compared with\nthe conventional methods. Different field tests, road tests, laboratory and numerical tests carried on geo-synthetics are also\ndiscussed. In this review paper comparison is made among geo-membrane, geo-grid, geo-cell, etc. in terms of their use.\nSuitability of different geo-synthetics is then discussed in terms of their use in bitumen, concrete and also in low traffic roads.
