Three-dimensional Finite elements models have been used to describe stress and strain response parameters for steel wire grid reinforced flexible pavement sections. In this study three paving sections were analyzed. The first section represents one of the commonly sections used in the paving of local roads, the second section is commonly used in expressways and the third section is used in freeways. Study was conducted using Finite element computer package ADINA. The reinforcement was arranged at different depths. Steel wire grid reinforced sections results are compared to geosynthetics grid reinforced sections as well as typical rigid pavement section commonly used in Egypt. The analysis showed that the best location of reinforcement is at bottom of base layer. Comparisons show that steel mesh reinforced sections characteristics improved than geosynthetics grids reinforced sections and are almost close to rigid section. |
