| dc.description.abstract | Various effects such as service loads, uncertainties in material characteristics, changing environmental conditions (precipitation and temperature), and geographical differences are largely responsible for the pavement performance. Use of mechanistic-empirical methods is increasing in the recent years, and many approaches based on experimental works leave their place to the mechanistic approaches which take into account several performance criteria. In many countries, project administrations or organizations have started to formulate their specifications based on these methods. These adaptation studies are also continuing in Turkey. Mechanistic design is generally used in flexible and rigid pavements, but for low-volume roads, its use limited due to the economic reasons. Seal coating is designed using empirical methods with ten years as “estimated project period” in Turkey, and since it is based on empirical approach, maintenance and repair activities are very common and serious financial costs arise in the service life. In this study, thickness of seal coats is handled with a mechanistic approach and a design algorithm has been proposed depending on the compressive strain on the top of the subgrade. Due to the acceptable axle load repetition into the service life, an analysis with KENPAVE has been performed, which is the amount of permanent deformation that is likely to occur at the end of ten years. In an economic evaluation, it was determined that the mechanistic method offered a relatively more expensive solution and the difference depended on the resilient modulus of the subgrade soils. | tr_TR |
