ECONOMICAL ANALYSIS OF PAVEMENT COMPOSITION USING BENKALMEN BEAM DEFLECTION METHOD

Abstract

Pavement degradation is a major issue in almost every country's road and traffic infrastructure. Bituminous pavement failures can be caused by a variety of factors or a combination of factors. Bituminous pavement failures can be caused by a variety of factors or a combination of factors. Pavement failure happens when an asphalt surface loses its original form and develops material tension, causing problems. Cracking, potholes, depressions, rutting, shoving, upheavals, and travelling are all signs of pavement collapse. This research examines the potential causes of pavement failures and suggests better ways to reduce, if not remove, the causes of bituminous pavement failures. Pavements are complicated structures with many factors to consider, including materials, construction techniques, loads, the environment, maintenance, and economics. As a result, numerous technological and economic factors must be thoroughly understood in order to plan, build, and maintain better pavements. Furthermore, due to the dynamic existence of road pavements, where elements of the pavement are continuously shifting, being added or removed, pavement maintenance problems are still complex. These components deteriorate over time, so keeping them in good working order necessitates a significant investment. In this report, new construction of a section of road overlay or some other preventative measure that is appropriate in terms of technical and financial viability may be included. The existing project road is consisting of single lane & intermediate lane and two lane configuration that is to be upgraded to 2 lane with granular shoulders configuration. The entire project road traverses through Barmer, Jalore, Pali districts. The major urban areas through which the project road traverses are Barmer, Rawatsar, Chawa, Sindhari, Sirana, Sayla, Ummedabad, Bishangarh, Sanderao, Falna, Mundara. The proper improvement measures for existing pavement for better performance of project road up to design life depends upon precisely done Pavement Investigations and Condition Surveys. To evaluate the existing pavement condition, various investigations were carried out. The above project case study is part of research area.
