Abstract: 

Fatigue cracking is one of the most prominent distresses in asphalt pavement. Considerable research has been done to develop theoretical models, experimental laboratory testing techniques, and data analysis methods to predict the fatigue performance of asphalt paving mixtures. The majority of fatigue studies were conducted in order to determine the curves and relationships that are called the transfer functions.
Usually, the transfer functions are given based on the test results conducted in more than 250 micro strains. But in long life pavements, we need to examine the behavior of asphalt mixtures in lower strains. Long life or the perpetual is defined as more than 40 years without any major structural failures or repairs.
