Abstract
The paper describes an investigation on fatigue of Asphalt Concrete modified by addition of crumb rubber as a pan of aggregates. Flexural fatigue tests on Asphalt Concrete and Rubber Modified Asphalt Concrete conducted at 20. 25 and 30°C under constant strain mode indicated that the fatigue life of Rubber Modified Asphalt Concrete is significantly higher than that of the plain Asphalt Concrete. Design charts are presented to show that the pavement with Rubber Modified Asphalt Concrete requires a lower design thickness.
