Comparative Analysis of Differerent Types of Pavement Based on Techno Economical and Life Cycle Cost

Abstract

In the developing countries the infrastructure development gives way for the development of country. On the same time the investment to the project development requires more cost and efficient maintenance. The road sector is very necessary because more than 60% of the passengers and goods are trawling through road. Hence good connectivity will ensure faster movement of traffic if the pavement is in good condition. Life Cycle Cost of Pavement is one tool to study of transportation project relating pavements starting from its design phase to its entire service life. In the present study a road stretch of 126.345 km from Chincholi to Shahapur is selected. And various data like pavement performance, material, traffic, climatic condition and economic data were collected and analyzed. Comparative life cycle cost for flexible pavement, rigid pavement and cement treated base pavements are carried out by designing a pavement for 30year life. In this flexible pavement was designed for design period of 15 year with maintenance of 15 years and rigid pavement for 30 years and cement treated base pavement for 15 years with maintenance 15 years to finalize optimum performing pavement based on construction and maintenance. Based on above study we conclude that construction cost of rigid pavement is reasonable and economical from km 0 + 000 to km 51 + 500 and the construction cost of cement treated base pavement is economical from km 51 + 500 to km 126 + 345 for the present road stretch.
