Over the years, the traffic load has increased and that requires higher-performing pavements, and the same can be achieved by using geogrids. The incorporation of geogrids will improve cracking and rutting resistance of asphalt pavements. However, the placement of the geosynthetics at the interface will reduce the bonding strength. Therefore, the geosynthetics are treated with chemicals to increase the bond strength. The main aim of this research is to produce treated geosynthetic reinforced asphalt pavement. To meet the objectives of the research, two type of geogrids such as polyester geogrid and glass fibre geogrids, and two asphalt mixtures Dense Bituminous Mixture (DBM), Bituminous Concrete (BC). Apart from these, geogrid reinforcement is studied at different positions (1/2, 2/3 and 1/4 distance from the bottom). The laboratory tests such as bond strength test, rutting, creep, and fatigue strength test are conducted on the geogrid reinforced asphalt pavements. A Control Mixture (CM) without geogrid is prepared, and the same is used for comparison purposes. Then the field test sections are constructed, and the performance studies (resilient modulus, fatigue, rutting and moisture resistance) are conducted. Finally, the life cycle analysis is performed to know the environmental impact of the treated geosynthetic reinforced asphalt pavement. Accordingly, the conclusions are made based on the laboratory and field test results. The preliminary test studies showed that the introduction of geosynthetics in the pavement layers improve the modulus by 20 %, which will increase the pavement performance towards rutting and fatigue. The geogrid reinforcement will reduce the pavement thickness by 10 – 20 %.
