Highway maintenance serves the primary purpose of providing a smooth and safe road surface for users at a minimal cost. However, paved roads in tropical and sub-tropical climates often suffer from different forms of deterioration compared to those in temperate regions, as harsh climatic conditions, inadequate design and quality control, high loads, and insufficient assessments contribute to failures. In the city of Bhopal, the JK road connecting Raisen Road to Minal Mall has a total length of 2 km, with approximately 55% of the road length in a state of failure. This study aims to investigate and classify the failure types of flexible pavements, identify their causes, and determine the most appropriate maintenance techniques. Common forms of flexible pavement failures include various types of cracks, potholes, raveling, water bleeding, corrugation, shoving depression, and rutting, which are gradually worsened by inadequate planning, inspection, and treatment. The possible reasons for flexible pavement failures include the use of improper bituminous mixes with low-quality materials, heavy traffic loads, heavy rainfall, and inadequate pavement drainage. To ensure the prolonged lifespan of road surfaces, proper maintenance is critical.
