Interlaboratory experiment of asphalt concrete using indirect tensile fatigue test

The principal purpose of this study was to evaluate repeatability and reproducibility of the Indirect Tensile Fatigue Test (ITFT) to quantify the fatigue resistance of asphalt concrete mixes according to EN 12697-24, annex E. A further purpose was to assess the performance of participant laboratories that apply this standard in routine use. A roadbase mix and high modulus asphalt concrete were chosen, representing the expected variation in the field. A total of eight laboratories around Europe participated in the study. Statistical protocols, including the International Standard ISO 5725-2, were utilized to describe the precision of the test. It was concluded that the ITFT is statistically rational and accurate, and is therefore recommended for use as a routine test standard to assess fatigue properties of asphalt mixtures.
