Nowadays, the increasing demand for road transport makes maintenance and repair of road infrastructures key tasks for road engineering.
The current experimental work consists of laboratory model experiments to understand the conduct of sand as a subgrade under dynamic load and its effect on the flexible pavement and base layer.
The reinforcement is applied at the interface between the base and subgrade using SS2 type of geogrid.
The road layers are exposed to harmonic dynamic load with two load amplitudes 10 and 15 kN and two frequencies 0.5 and 1 Hz.
The vertical stresses in the road layers are measured using stress gauge sensor.
In the case of a reinforcing geogrid at the middle of base course, the stress decreases by increasing the frequency and load amplitudes by about (23-42).
The best position for geogrid is in the middle of crushed stone layer because it gives lower displacement.
In the case of a reinforcing layer at the middle of base course layer, the stress and vertical displacement decrease with increase in frequency and load amplitudes.
When laying the geogrid between the base course and subgrade, a lower decrease in the stress and vertical displacement could be obtained with the increase in frequency and Nowadays, the increasing demand for road transport makes maintenance and repair of road infrastructures key tasks for road engineering.
