There can be devastating direct and indirect consequences when slope failures occur along roads. To improve the stability of slopes, slope stabilisation measures are implemented. When there is a lack of attention given to slope stabilisation in the haphazard construction/maintenance of roads, the risk of slope failure is exacerbated. This scenario can be common in many low-income countries that have fewer available resources. My PhD aims to improve the cost-effectiveness of slope stabilisation along roads in lower-income countries by: (1) developing road slope cutting guidelines; and (2) by developing a methodology to assess the cost-effectiveness of slope stabilisation.
Cost-effectiveness is a measure of how effective an intervention is in relation to its cost. My PhD aims to develop a methodology to establish the cost-effectiveness of slope stabilisation measures currently found along roads in lower incomes countries. By implementing this methodology, an appropriate intervention can be chosen based on fund availability.
