Pavement Project of Forest Roads Using Fuzzy Logic

Turkey is not possible in the existing forest roads with very little of the superstructure and the remaining majority uncoated and transport of wood raw material in an expeditious manner in all seasons due to the unfounded nature of the soil in the road. For this reason, the application of forest roads in all forest areas rapidly and to the construction technique The necessity of choosing the materials and thickness of the three layers mentioned above on the forest roads, in other words, the most important issue of the superstructure.Forest roads show some differences compared to other engineering structures. Due to the length of the roads, the floor of the superstructure can vary from point to point. The superstructure is made of different materials. For this reason, superstructure design is one of the most complex subjects of engineering. Computer programs play an important role in speed, precision and time in engineering calculations. AASHTO 1986 flexible superstructure can be obtained by SN trial-error due to the excess of parameters in the calculation formula and the mathematical complexity of the formula. The aim of this study is to develop a fuzzy logic model related to AASHTO 1986 flexible pavement calculation method which is one of the methods used in designing flexible pavements. With this model, the formula results can be highly predicted. Fuzzy logic method can be used as an important tool for researchers and practitioners working in forest road engineering.
