Effect of Geo-Grid Depth in Roads Cross-Section on Reducing Pavement Rutting

Pavement structures cover vast areas of urban cities and non-urban roads play a key role in daily commuting functionality economic development; therefore, they must be conserved against any distress. The rutting problem, being major distress to the pavement structure, solved dealt with order preserve its value. One way solving this dilemma is by using geo-grids within structure. A geo-grid synthetic material usually made from polymers different thicknesses stiffnesses. This paper investigates effects on reducing occurrence through adding layer certain properties at levels We also investigate, result added developed vertical stresses cross-section. investigation conducted constructing 3-D finite elements-based (FE) model cross-section ANSYS software; student version R1 2021. FE-based validated comparing numerical predictions experimental results acquired an accelerated large-scale paved model. show that deeper positioned, more significant resistance observed due stiffness bearing tensile force until depth. Moreover, noticeable stress reduction seen compressive below loading area resisted geo-grid.
