Geologically, the affected area is comprised mainly of sandy insitu soil with weathered sandstone, clay, thin bed of unconsolidated pebbles and cobbles.  Toe cutting of slope destabilized the slope. The weak overburden on over saturation develops local p

This road stretch is dotted with minor cut slope failures. Therefore, proper remedial measures should be adopted as a precaution against future incidences.
Kepre Tongikro Mongjang slide No.8
Kepre Tongikro Mongjang road section.
1. Timely maintenance of lined hillside draiNGe system.
2. Moderation of slope gradient/dressing of slope may be considered.
3. Toe support for the affected slope through construction of strong concrete retaining wall with sufficient weep holes.

1. Destabilization of slope due to ill planned cutting for road construction.
2. Weak slope forming material comprising mainly of insitu soil underlain by highly weathered friable sandstone.
3. Overburden thickness of 0.5ΓÇô2m.
4. Reduction of slope m
