Angle of friction in reinforced earth

Abstract EN

The present work took care of the frictional resistance developed between the fill material and mats used as soil reinforcement which are made of locally natural materials.

These natural materials are locally available plant organs, which are cheap and abundant, and are expected to result in lower construction cost.

The angle of friction is 0.

77 < f > between these plant mats and the sand, where 0 is the angle of internal friction of sand.

The asphalt bitumen used as a protection coat against moisture and destructive organs, was found to result also in increasing the angle of friction between these mats and the sand to 0.
