Airport runways are built to exacting, internationallymandated standards. But frequent landing and take-off of flights lead to wear and tear of runways. Natural weather phenomena like rain and sun also affect the runway surface.Re-carpeting is essential for the safety of flights. All re-carpeting activities on runways are likely to lead to flights being rescheduled though they are not always cancelled or disrupted. Airport runways at all times need to be of a specified strength or Load Classification Number (LCN), which is a system of classification of the supporting capacity of pavements without cracking or becoming permanently deformed. Airport pavements are constructed to provide adequate support for the landing. In order to satisfactory, the pavement must be with quality and adequate thickness that it will not fail under the loads. In addition, it must possess sufficient inherent stability to withstand, without damage, the abrasive action of traffic, adverse weather conditions, and other deteriorating influences. To produce such pavements requires a coordination of many factors of design construction, and inspection to assure the best possible combination of available materials and a high standard of workmanship. The paper deals with the various methods involves in strengthening of runway pavement by examining the runway for a variety of issues including whether the aircraft is having a smooth ride as it lands, rubber deposits and removal, raveling observed at touchdown zone and rubber removal area, reflection cracks, patching on runway, pop outs and coarse aggregate loss, alligator cracking, surface irregularities on the line markings, shoving and uneven surface. Software results by considering number of flights along with loading damage ratio is calculated which results in thickness for re-carpeting further this ratio is considered for thickness of pavement if number of flights increase.
