抄録

In this paper, the approach for small scale road improvement towards development where no one left behind are discussed. Though so many road development project has been conducted so far, there are still a lot of road in poor condition, especially in rural area. The authors had proposed to utilize labour intensive and locally available material based method to improve small scale unpaved road but the lifeline for people. As a specific method like proposed, Do-nou, which means soil bag in Japanese, method for building base course was developed. The applied method including Do-nou method has enabled roadside communities to play dominant roles in road improvement project not just as paid labour. On the other hand, it has found that even with the simple and applicable method, stakeholders' support to communities is required in terms of provisions of material and capacity building for group management, material procurement, store/tool management, and other basic road maintenance technique.

Based on the scope of works on road improvement, the suitable work structure and required capacities are summarized through case studies on road improvement projects in Asia and Africa. It is envisaged that the summary of road improvement approach where community play major role would contribute to make road authorities and donors understand the scope of works and develop the road project with appropriate target, thus the small scale road network become accessible.
