The use of marginal and waste materials in low volume roads Supervisor Dr. John Oliphant Abstract Low volume rural roads are roads, which provide access to the rural areas and have a low traffic volume, normally less than 100 heavy vehicles per day. They act as feeder routes to and from mines, forestry, industry, tourism and agricultural areas. In developing countries such as Tanzania, a large population live in rural areas where people are mostly engaged in agricultural activities.
Most areas are only accessible by road.
Without a system of all weather roads, the rural community will neither be able to contribute to nor benefit from the development processes. Most of the locally available raw materials in tropical countries like Tanzania, do not meet the specifications for road base construction materials. Due to extensive weathering in tropical climatic conditions, good quality rock is generally difficult to locate. In developed countries such as United Kingdom, a lot of construction and industrial activities have been undertaken, while other activities are still going on. The construction industry normally uses large quantities of raw material as well as finished products.
