Provides an analysis of rural road maintenance in the Asian region.

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Provides an analysis of rural road maintenance in the Asian region.

The purpose of this manual is to assist maintenance groups in Yunnan Province, People’s Republic of China, in organizing and carrying out the routine maintenance of unpaved rural roads.

Roads and water are generally seen as enemies, with water responsible for most of the damage to roads, and roads being a major cause of problems such as erosion, waterlogging, flooding, and dust storms. This tension, however, can be reversed. The concept of Green Roads for Water (also known as “Green Roads†? or “roads for water†?) places roads in the service of water and landscape management and climate resilience without sacrificing or diminishing their transport functions. With global investment in roads of US$1†“US$2 trillion per year, plus maintenance costs, the widespread adoption of Green Roads approaches can leverage investment at a transformative scale, making road development and maintenance a vital tool for achieving climate resilience, water security, and productive use of natural resources. Green Roads for Water: Guidelines for Road Infrastructure in Support of Water Management and Climate Resilience provides strategies to use roads for beneficial water management tailored to diverse landscapes and climates, including watershed areas, semiarid climates, coastal lowlands, mountainous areas, and floodplains. The underlying premise of Green Roads is therefore quite simple: designing roads to fit their natural and anthropomorphic contexts; minimize externalities; and balance preservation of the road, water resources, landscape, and soil resources will usually cost less than traditional protective resilience approaches and will produce more sustainable overall outcomes.

Singling out roads as an important factor in economic development, this report presents the findings of a regional technical assistance inquiry carried out to examine the problem of road funding in Asia with the aim of proposing case-specific solutions. Particular attention is paid to the data collected during road assessments performed in the Kyrgyz Republic, Pakistan, Uzbekistan, and Vietnam. Also discussed are a number of possible strategies for combating road-maintenance neglect across Asia.
