Reinforcement interlayer reduces the development of cracks in the asphalt overlayby orbing the stresses induced by heavy traffic or underlying cracking in theearly-constructed pavement.
This research is dedicated to studying the behavior ofpavement layers on a sand subgrade under simulated effect of earthquake.
In thisstudy, the sand layer has a thickness of 600 mm and the base course is taken as300 mm.
The asphalt layer was prepared as a panel with dimensions of 300 × 300× 50, which represents the surface layer.
These layers are experimentally testedunder the influence of earthquake loading with different frequencies 0.5, 1, 1.5 Hz.
The tests consist of two parts without adding the geogrid, with geogrid in the centerof the base layer and between the base layer and sand layer.
Loaded stresses in thethree layers are monitored using stress gauge sensors, while displacements of theasphalt layer by using displacement gauge sensor.
Obtained results consideredmodels reinforced with geogrid, the stress recorded is higher than in unreinforcedmodels but the displacement decreases by increasing the geogrid in the layers atthree frequencies.
When the geogrid is laid between the base course and sand layer, the stress in the sand subgrade layer is less than that in the base and asphalt Reinforcement interlayer reduces the development of cracks in the asphalt overlayby orbing the stresses induced by heavy traffic or underlying cracking in theearly-constructed pavement.
