Abstract

Increasing the movement of goods on Egyptian roads network and the increase in fuel prices lead to increase truck loads on roads causing several harmful effects. An urgent need to treat the current road sections against these effects and to define a new design axle load for Egyptian
roads becomes essential. The main objective of this study is to investigate
the recommended common design axle load. To predict the common
design axle load, real weighting of truck axles was conducted on
representative sample for Egyptian roads in weight stations. The most
important objective of this study is to investigate the effect of using steel
wire grid reinforcement on the performance of pavement sections. The
reinforced pavement sections are mode led and analyzed using two-
dimensional finite elements method and three-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. A comparison between the results of
the two-dimensional finite elements models (2-D-FEM) and Three-
dimensional Finite elements models (3-D-FEM) were obtained. Finally,
comparison between the allowed legal axle load and common design axle
load. 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
