Bausher – Al Amerat Road is a 4-lane dual carriageway arterial mountainous highway having length of 14.5 km.

The design is finalized to study the stability conditions of the existing rock cuts and to analyze the proper protection measures for the stabilization of the road.

The investigated area presents high variability of rock formations, with presence of metamorphic rocks as schist and metagraywacke or sedimentary rocks as sandstone, dolomite and limestone in different grades of weathering.

During the Geological Survey several areas of heavy weathering of rock surface and local collapses were detected, which have determined the loss of berms with consequent hazard of rock falls in the carriageways due to.

• Detachment of boulders, layers and wedges
• Collapse along clay-infilled discontinuity
• Accumulation of material on the berms, due both to excavation activities and weathering of rock surface
• Erosion in correspondence of loose or weathered rock

In order to assess the rock-fall hazard, the Rockfall Hazard Rating System (RHRS) has been chosen.
