Received 01 March 2019; Accepted 05 June 2019 Abstract Pavements are major means of highway infrastructure. Maintenance and rehabilitation of these pavements for the required serviceability is a routine problem faced by highway engineers and organizations. Improvement in road management system results in reduction of time and cost, the pavement condition survey plays a big role in the pavement management. The initial phase in setting up a pavement management system (PMS) is road network identification. A vital element of a PMS is the capacity to assess the present condition of a pavement network and anticipation of future condition. The pavement condition index (PCI) is a numerical index generally utilized for the assessment of the operational condition & structural reliability of pavements. Estimation of the PCI is dependent on the results of a visual inspection in which the type, severity, and quantity of distresses are distinguished. In this research, a pavement distress condition rating strategy was utilized to accomplish the goals of this study. The main targets of this research were to categorize the common types of distress that exist on “Lakhi Larkana National Highway (N-105)”, and to estimate the pavement condition index. Using these data, Average PCI for the highway section was calculated. PCI to assess the pavement performance, 10 out of 19 defects were recognized in the pavement, as stated by the PCI method. Results indicated that the common pavement distress types were depressions, polished aggregate, rutting, potholes, block cracking, and alligator cracking. Keywords: Pavement Management System (PMS); Visual Condition Survey; Corrected Deduct Values (CDV); Pavement Condition Index (PCI). 1. Introduction The pavement condition and traffic speed are considered as operative and important factors that affect the efficiency of highway systems. The surface rehabilitation of multilane highways should be awarded a high priority by highway establishments, as this represents an important component of the road network [1]. The Traffic speed is a significant factor because it determines safety, time, comfort, convenience, and economics, and is an important indication for predicting pavement condition and surface roughness of roadways. Transportation engineering deals primarily with moving people and goods from one place to another, using waterways, railways, highways and air space. Railways and roads are used for on-land (and underground) transportation by train and vehicles such as cars, busses and trucks. In Pakistan, the largest part of transportation operation is conducted by using highways. The paved length of roads (164,621 km) is more than 14 times the total length of rail tracks (11,881 km) [2]. * Corresponding author: Jaffar.memon@muetkhp.edu.pk http://dx.doi.org/10.28991/cej-2019-03091338 © 2019 by the authors.
