Fatigue and Resilient Characteristics of Asphalt Mixtures by Repeated-Load Indirect Tensile Test
The mixtures studied contained crushed limestone or rounded gravel aggregates and an AC-10 asphalt cement ranging from 4 to 8 percent by weight of total mixture. The fatigue and repeated-load tests were conducted at 50, 75, and 100 F, with the stress level ranging between 8 and 120 psi. From the static tests, an equation which predicts indirect tensile strength in terms of testing temperature and mixture properties was developed. In addition, a strong relationship was found to exist between static modulus of elasticity and indirect tensile strength. From the fatigue study, relationships between fatigue life and various test variables and mixture properties were evaluated and equations were developed for predicting fatigue life from initial strain and from the ratio of repeated tensile stress to the average indirect tensile strength.
