Drainage is one of the most important factors to be considered in the road design, constructionrnand maintenance projects. It is generally accepted that road structures work well and last longerrnto give the desired service. When a road fails, whether it is concrete, asphalt or gravel,rninadequate drainage is often a major factor to be considered. A pavement distress that occurs atrnthe surface can have a number of different causes which must be properly identified beforerncorrective action is taken. The visible manifestation of the problem at the surface may be thernsame; however, the solution for each cause may be different. Therefore, if the remedial actionrnis to be effective, the cause of the problem must be identified and corrected.rnThe present road condition of Burayu shows rapid deterioration. The severity of pavementrndistresses is even more critical on the major arterial roads were the traffic volume of busses,rnheavy trucks, passenger vehicles and taxies is comparatively higher than other roadrnnetwork. Such severe distresses summed up with inadequate road signs and markings arernresulting congestion and consequently causing further deterioration of roads due to maximumrnstatic load sustained from the vehicular traffic waiting in a queue on the pavement.rnThis research mainly focuses on making assessment of road pavement condition, identifyingrncauses of pavement distress and proposing maintenance options for the arterial roads ofrnBurayu. These roads are most widely utilized, and therefore prone to severe distress andrnconsequently exhibiting repeated maintenance and repair. Visual distress assessment, and otherrnnecessary investigations were carried out on selected test road sections in order to have betterrnunderstanding of the pavement response and come up with identification of probable causes.rnMajor causes of pavement distress associated with load, drainage and durability are tried to bernidentified.rnThe visual survey analysis indicates that almost all test roads have very low PCI value.rnRaveling, corrugation, Bumps and sags are the most dominant type of distresses constitutingrnmore than 75% of the distress densities in the arterial road network. The majority of testrnsections showing low PCI values. The investigation and analysis also showed that moisture andrndrainage associated distresses are predominant in the arterial roads and most likely on thernwhole network as well. Moreover, it is also observed that most of the existing pavements lackrnstructural adequacy and hence require reconstruction than doing a routine maintenance and/orrnrehabilitation.rnKeywords: Road Drainage System, Urban Road, Maintenance, Flood damage,
