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.
