A study was conducted on the NH-146 Bhopal-Sagar National Highway to assess the pavement quality and distress type using the Pavement Condition Index (PCI). A study of flexible pavement distress has been conducted on the NH-146 Bhopal-Sagar National Highway for 1.0 km from Agarwal Restaurant to Asha Ramji Ashram towards Bhopal. The PCI is a quantitative and qualitative assessment based on visual inspection, classified in natural numbers between 0 and 100. The study aimed to investigate typical failures of flexible pavement under the Vidisha City Corporation area and NHAI. This methodology is a prominent tool for road management and life-cost analysis. The results showed that the PCI values are high at some chains for all distress. For alligator cracks, rehabilitation is required on the top layer and a proper additional surface course is needed with a fresh layer of bitumen as per design and quality standards. This may be economical then by providing the overlay for the whole pavement. Potholes, it can be covered by premix material after cleaning and painted with the bituminous binder. Patches are the one kind of improvement for the pavement. An entire damaged area is selected and covered/filled with a fresh layer of bitumen. So, it can be economical as compared to demolishing the whole pavement ground. The Total maintenance cost of the 1km stretch is 198509.04 Indian Rupees.
