Abstract

The economical development of a country is closely related to its road transport infrastructure facilities available. The periodic maintenance of the road is limited due to cost consideration which will disrupt the service and affect the function of the road. To overcome these constraints, Geotextiles shall be used in pavements to extend the service life of the pavement which requires less repair and maintenance and also reduces the total thickness of the pavement system. In this paper, an attempt is made to enhance the performance of the flexible pavement using woven geotextiles and non-woven geotextiles between the layers of soft subgrade and base course and also effective utilization of flyash in subgrade for stabilization. Flyash stabilization along with inclusion of geotextiles increases the California Bearing Ratio (CBR) value in unsoaked and soaked condition. The performance of non woven geotextiles is better when compared to woven geotextiles because of its better puncture resistance when subjected to impact loading and also good drainage properties than woven geotextiles.
