La función principal de la geomalla de fibra de vidrio
Reflective cracks are caused by the large displacement of the old concrete surface near the joints or cracks that cause stress concentration in the asphalt overlay above it. It includes horizontal displacement due to changes in temperature and humidity, and due to traffic loads. The vertical shear displacement is caused by the action. The former causes concentrated tensile stress in the asphalt overlay above the joint or crack; the latter causes the asphalt overlay above the joint to undergo greater flexural tensile stress and shear stress.
