... into the subgrade soil with consequent reduction of subbase layer thickness. When a geotextile layer is placed between the subbase and subgrade layers, it acts as a separator and, thus, prevents the intermixing of the two layers. However, the geotextile allows for rapid dissipation of the cyclic pore pressures...

... of tension under the subbase particles; (ii) the development of a gap under the subbase particles; (iii) the plastic flow of subgrade soil into the gap; and (iv) global separation in which a gap develops between the underside of the geotextile and the top of the subgrade. Two mechanisms of geotextile...
