M.Y. Ahmed, F. Islam, A.H. Nury and M.J.B. Alam    

Abstract: The primary function of pavement is to distribute the concentrated loads so that supporting capacity of the sub-grade soil is not exceeded. Due to continuous application of impact loading, pavement surface often subjected to various types of distresses. The study was conducted on a portion (madina market to tuker bazar) of Sylhet-Sunamganj road that acts as a very important link between two adjacent towns. Pavement Condition Ratings (PCR) of the pavement was obtained on the basis of severity and extent of different types of distresses such as alligator cracks, longitudinal cracks, potholes, rutting, raveling, patching, etc. The PCR values of different segments of madina market to tuker bazar were evaluated in this study most of which fall within the category of very poor to poor conditions. Such condition of PCR immediately recommends proper treatment of the pavement for usage convenience.
