Problem: – Some of the stretches of PMGSY roads in the state of Karnataka are under weak soils
which affects the long term performance of these roads, in order to provide all weather roads
for areas with soft and weak soils, it is necessary to adopt suitable technologies which enhance
the pavement life and functioning.
Solution: – CM3- Confinement Mat is expanded on-site to form a honeycomb like structure, which
is in filled with granular infill which creates unique cellular confinement system. CM3- Confinement
Mat will increase the shear strength of the confined soil, and increase load carrying capacity. With
granular infill material and holes in CM3- Confinement Mat, it enhances drainage and release pore
water pressure. CM3- Confinement Mat is used for soil confinement, stabilization and
reinforcement in wide variety of load support applications
