Assessment of flexible pavement fatigue life of Turkish typical sections using mechanistic empirical pavement design approach for coastal region

Abstract

Due to rapid progressing in the economy of Turkey, the Turkish Transportation Authority has increased the Motorway and Provincial road lengths. The ESALs have reached several hundreds of millions and accompanied with an increase in the weights of axles. The old AASHTO 1993 is still the design method used in Turkey. This method has many limitations due to, the authors in this work are trying to use the new Mechanistic-Empirical M-E Pavement Design method for the assessment of the Fatigue Life FL of Typical Sections in Turkey TTS. The Coastal (hotter) Region is selected. Antalya city is representing the climate of Coastal Region. The MnPave M-E design software has been used for the calculations. Many types of asphalt have been used to study the effect of asphalt type on FL. The results were very important and the recommendation of the transition of Turkey towards the new M-EDM is recorded.
