Toward climate-resilient roads: Climate change adaptation measures for the road sector in Timor-Leste

This study aims to identify the causes of damage to roads and bridges; plan effective climate change adaptation measures; introduce innovative technologies suitable for adaptation; and strengthen the capacity of government engineers to properly oversee the design, construction, and maintenance of road and bridge infrastructures.

For each road damage case, the study identified causes, measurement methods, and countermeasures. For landslides, a comprehensive approach was recommended, using data from satellite imagery, topographic and geological maps, and aerial drone photography. For cut slope failure, the study recommended countermeasures such as rockfall prevention nets and shotcrete. For fill slope failure and settlement, the study identified external factors such as unstable foundations, high rainwater infiltration, erosion during floods, and erosion at the outlet of the culvert.
