Abstract
The process for developing a structural design method for airport asphalt pavements with lean concrete base from experimental tests was described. First, the structural and functional capabilities of the pavement structure were investigated. It was revealed that joint is the critical loading position, and that both a thicker asphalt surface course and a crusher-run subbase are beneficial. Then, the structural parameters were studied through back-calculation and calibration. By using the elastic-layered system theory, the design principle was developed considering the influence of the joint and the fatigue property of the lean concrete base. Finally, applications of the design principle were investigated.
