This paper begins with a definition of low-volume roads, then proceeds to discuss the consequences of the eventual deterioration of low-volume roads. It is pointed out that the conditions under which studies and construction are carried out may increase the risks of deterioration, in one or more of the following ways: uncertainties as to traffic volume; limited geological and geotechnical surveys; general drainage; and little control over the characteristics of the construction materials used. Seeking to reduce risks of interruption to traffic, and obtain better value for money, two lines of action are suggested: (1) Due to the extreme sensitivity of low-volume roads to weather conditions and to the nature of the soils and to the effects of the loads they support, improved performances could be obtained by carrying out far more comprehensive studies than is customary, especially in the field of geotechnics and drainage; and (2) An economic optimum is not solely determined by a tradeoff between initial investment and maintenance spending under these conditions; construction cost inputs should be augmented by realistic investment rates based on average values.
