A Comparative Study of Pavement Evaluation using PCI and PCN: Review Article

Pavement evaluation is a critical aspect of maintaining a safe and functional transportation infrastructure. Two commonly used methods for pavement evaluation are the Pavement Condition Index (PCI) and the Pavement Condition Number (PCN). This paper aims to provide a comparative study of these two methods, highlighting their strengths, weaknesses, and areas of application. Roads and airfields are the most used communication means to connect people around the world. The infrastructure of a country is an important parameter for the economic and social health of a country. The number of people using this mean of communication is growing every year. Better and long lasting pavements are needed to meet the present requirements for transport infrastructure. Air travel demand has experienced very rapid increase in the last two decades. With increased industrialization and economic growth, the number of air passengers and freight is projected to rise even more rapidly in the near future. Continued growth in traffic requires successful longer term advance planning and a systematic approach to the design, construction and operation of future airports. Among this increasing air travel demand there should be paramount consideration about the airfield pavement. A runway pavement is expected to deteriorate heavily in the long run due to increasing air traffic in India. To adequately assess the causes of performance breakdowns in existing airport systems and to plan facilities to meet future demand needs, it is essential to predict the level and distribution of demand of the various components of airport system.
