Title: Fatigue and Healing of Asphalt Mixtures: Discriminate Analysis of Fatigue Curves
Abstract: Fatigue laws obtained by means of laboratory tests do not usually take into account the fact that asphalt mixtures in highways have rest periods (without loads). These rest periods tend to increase the fatigue life of mixtures due to the phenomenon known as healing. A new fatigue test which includes rest periods has been developed. In order to study healing, tests with and without rest have been carried out on asphalt concrete, and the corresponding fatigue curves have been obtained. The test results show an increase of five to ten times fatigue strength. This paper summarizes the main experiences. The testing method used in the research is described. The results are analyzed by means of a statistical technique called discriminate analysis.
