| Abstract | Direct s h ear and Pullout tests were conducted on
lateritic residual soil to evaluate the soil-reinforcement
interaction at low normal pressures. The tests were carried out at dry and wet side of optimum with compaction density of
95% standard proctor density as well as at optimum moisture
content at 10096 of the standard proctor compaction density.
In t h e pullout tests, the soil compaction was achieved with
Wacker tamping machine , while the densities and water contents
were checked for uniformity by using the Troxler Nuclear gage.
Electrical resistance strain gauges were used to evaluate the
in-soil strain response and the stress transfer mechanism,
while the mat displacement at front was measured with a dial
gauge and checked with a linear variable differential
transformer (LVDT) . The data acquisition system recorded the
mat displacements and axial tension i n the wires u sing the 21X
micro logger. The tests showed the pullout resistance to be a
function of t h e vertical nor mal stress and the mat parameters.
150 X 225 X 6 mm diameter welded wire mesh was found to be
more efficient than 150 X 150 X 6 mm, 150 X 150 X 12 mm and
150 X 225 X 12 mm diameter meshes, so far tested with
compacted lateritic soil as a backfill in this study, in
exploiting passive resistance in front of the transverse
members of the mesh. |
