Abstract
Rural roads and passages form a major part of the country's roads, which play a constructive role in the quality of traffic and the relative well-being of the villagers. This research was carried out in a descriptive way and by reasoning to books, sources and authentic library texts and by collecting and referring to field studies taken from objective observations as well as their analysis, which aims to develop and expand quality pavement as well as Introducing the correct methods and solutions for prevention and timely maintenance of the failures in the asphalt paving of rural roads. In this research, major damages in rural roads and roads were investigated and analyzed to find the best way to repair them. The obtained results indicated the existence of major damages including alligator cracks, block cracks, longitudinal and transverse cracks, corrugation, potholes, etc. It has been proposed, for alligator cracks, as the most common cracks, the staining method, apply seal coat and improve the load-bearing condition of the subgrade soil, and for other defects, various methods to improve the condition of the defect have been presented in detail. It is easy to minimize the damage caused by most of these failures by properly monitoring the implementation and sufficient precision in the design. By carrying out a basic and technical design of a suitable pavement as well as its correct implementation, it is possible to use that pavement properly for many years. Proper attention and planning to use suitable maintenance options is very important.
