This study aims to investigate the effect of using steel wire grid reinforcement on the performance of
pavement sections. The reinforced pavement sections are modeled and analyzed using two-dimensional finite
elements method. Study was using the ADINA finite element program. 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. 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 in all investigated pavement sections. Comparisons
show that steel mesh reinforced sections performance improved than geosynthetics grid reinforced sections and
almost close to rigid section.
