Durable and Economical Construction of Rural Roads
In recent years, applications of industrial wastes have been considered in road construction with great interest in many industrialized and developing countries.
Rural road connectivity is one of the key components for rural development in Indian context, as it promotes access to economic and social services, generating increased agricultural income and productive employment in various parts of the country. The conventional methods and specifications tend to recommend products and technologies, however difficult and distance away they may be, which normally results in higher cost of construction, could not become popular due to procedural constraints, lack of awareness, and exposure. At this juncture, an attempt is made to bring in together innovations and discuss their positive impacts so as to convince the field engineers and stakeholders in adopting the effective products and technologies. The rural roads asset created using the valuable environmental resources such as precious soil, stone, and other products, it has to be maintained to deliver the desired level of service in the design life. In recent years, applications of industrial wastes have been considered in road construction with great interest in many industrialized and developing countries. The use of these materials in road construction is based on various technical, economic, and ecological criteria for which a critical review has been presented in this paper.
