The Ministry of Works Malaysia (MWM) was dealing with backlog in maintaining federal roads due to insufficient allocation and increasing traffic volume. This research is significant to assist the government draw up the cost allocation for rehabilitation plan in the state of Kelantan especially along federal road in Kuala Krai district. A case study was carried out on the federal roads under Public Works Department (PWD) management in Kuala Krai district which is the concession contract that awarded to Roadcare Sdn. Bhd. The distress of flexible pavement were divided into four main categories which were potholes, pavement cracks, surface deformation and surface defects. This 54km road has been divided into five segments of road section. The data analysis was conducted based on routine inspection records, notification of defects and Road Traffic Volume Malaysia produced by Roadcare Sdn. Bhd and Ministry of Works Malaysia. From the study, pavement cracks is the dominant defect mechanism from 2016 to 2018. Potholes and surface defects indicates the upward trend from 2016 to 2019 along Jalan Kuala Krai-Gua Musang. Meanwhile, the highest estimated cost for road rehabilitation for 4 years contributed by segment 5 due to the highest area of pavement distress that occurs along this. Because of the location of segment 5 which is near to the city center with lots of industrial and business activities, therefore, the most of the budget in maintenance has been spent along segment 5.
