A small-scale model of a pavement section was constructed and subjected to repeated loading tests in a centrifuge. Resilient tensile strains were measured at the bottom of the asphalt layer and the accumulated permanent deformations near the pavement surface. The models were tested to 10,000 repetitions, but more than one million repetitions may be required to induce fatigue cracking. A static load test also was performed after the repeated load test.
