Technical Paper 2.1 – Behaviour of Engineered Natural Surfaced Roads
Information on the feasibility of using ENS roads within a range of Cambodian environments. Existing knowledge is reviewed. Data is collected and analyzed on a range of roads with natural surfaces or unsealed surfaces of poor quality materials.
Technical Paper 2.2 – Behaviour of engineered natural surfaced roads: experimental evidence in Cambodia
The study illustrated the complexity of performance of ENS roads and highlighted the reasons why deriving general specifications has proved elusive. It confirmed the need for locally derived flexible specifications that are relevant to the local materials and the road tasks. The results of the study are encouraging and indicated that, with longer term monitoring, the outstanding questions can be resolved
