Landslide impacts on the road network of Lao PDR and the feasibility of implementing a slope management programme

The impact of landslides on the national road network of Laos is, on the whole, considered to be less than it is in some other Asian countries. The majority of landslides affecting the national road network appear to be related to shallow and localised slope failures in cut slopes. Nevertheless, failures occurring on slopes below sections of road are also common and these have given rise, in places, to loss of road edge and sometimes failure of adjacent carriageway. The economic evaluations undertaken indicate that the engineering benefits to be accrued from increased investment in pro-active slope management are marginal. However, for those road alignments within the network that suffer the greatest degree of landslide hazard, investment in pro-active slope management is considered likely to be beneficial, in terms of the combined engineering return on the investment (reduced operational and maintenance costs) and reduced costs associated with traffic delays.
