Highway economic analysis, also known as highway project appraisal, involves quantification of the costs of and benefits from a scheme over a selected time horizon and evaluation by a common yardstick. The technique is also known as benefit-cost analysis. Such economic evaluation serves a number of purposes: (i) To rank different schemes within the highway sector. (ii) To assist in [...]
In this article we will discuss about how to design plain jointed rigid pavements for highways by IRC Method. IRC Method of Rigid Pavement Design: This method is based on mechanistic-empirical principles and the use of software IITRIGID for the computation of flexural stresses due to single and tandem axle loads. The design of a rigid pavement consists of: (i) [...]
Concrete Roads: PQC, Methods of Construction and How it is Made! Introduction to Concrete Roads: Concrete roads fall under the category of high quality/superior type of roads built with cement concrete. These pavements may or may not be provided with sub-base/base courses, and they may be constructed directly over a well-compacted soil subgrade. They derive their strength to support the [...]
