Observational analysis shows significant strain reduction in flexible pavement with geotextile reinforcement, indicating improved structural performance.
When exposed to static and dynamic traffic loading, road pavements can exhibit degradation and permanent surface deformation. This study examined the impact of dynamic loading on the layers of a flexible pavement. This study used two types of geotextile (woven and non-woven) as reinforcements. Two cases were investigated; the first one by placing the reinforcement within the wearing layer, and the other one by placing it between the wearing and base layers. The road layers experienced a harmonic dynamic load with an amplitude of 1.5 tons and a frequency of 0.25 Hz. The measurement of strain in the layers of the road was carried out using a strain gauge sensor. The results indicated that when geotextile was placed between the wearing and base layers, it provided a better reinforcement with a reduction of 74.8% in strain using woven geotextile.
