When exposed to static and dynamic traffic loading, road pavements can exhibit degradation and permanent surface deformation. This study examined the impact of dynamic load on the layers of a flexible pavement. This study used two types of geotextile (woven and non-woven) as reinforcements. Two cases were investigated, one by placing the reinforcement within the wearing layer whereas the other case 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 base and wearing layers it provided better reinforcement with a reduction of 74.8% in strain using woven geotextile
