Analysis of Pavement Deterioration

Abstract

Transportation plays an important role in the economic growth and development of the country. One of the primary responsibility of the Transportation department is to maintain their network. The surface quality and surface roughness has a strong influence on the public judgement of its serviceability. Pavement deterioration is a continuous process which need to be taken care of by applying some maintenance and improvement standards. There are various distresses that we have to deal with to maintain the pavement condition and to provide a better surface quality. Here in this research 3 important distresses i.e. Raveling, Rut depth and Cracking are considered. The value of these distresses are analyzed using HDM-4 software. The changes in the values of these distresses in different roads in different traffic and climate condition is found out. According to the values of different distresses, graphs are plotted and the suitable trend lines are drawn. The equation of different trend lines are found out.
