Abstract
- A pavement structure consists of several layers for the primary purpose of transmitting and distributing traffic loads to the subgrade. Rutting is one form of pavement distresses that may influence the performance of road pavements. Soft subgrade soils are distinguished by their low undrianed shear strength and high compressibility. The effect of geogrid and steel mesh to improve the performance pavement is experimentally investigated and evaluated. To compare the experimental and analytical outputs, three dimensions finite element throughout models using ABAQUS ver.6.12.3 software are developed to simulate and analyze the relations between the cycling load and deformation of the suggested pavement modes. Based on the results and the limitation of this study it is concluded that, using geogrid and steel mesh in pavement layers leads to increases in load carrying capacity and decrease the permanent deformation in surface pavement for (1000) cycles load by (27.3%) and (18.3%) respectively, as compared with unreinforced model. The results of ABAQUS program are very close to results of laboratory tests.
