| Abstract: | Flexible base asphalt pavement and compound base asphalt pavement are new pavement structures in China,so its deflection index value is not fit to current standard system.Through a large number of experiments this paper reveals the deflection indexes development law of graded broken stone subgrade,analyzes the correlation of deflection index between graded broken stone subgrade top and asphalt pavement top.Finally,the control standard of deflection index for the new pavement structure is proposed. |
