METHODS FOR ESTIMATING REMAINING LIFE OF CEMENT CONCRETE PAVEMENT OF MILITARY AIRPORT

摘要

On the basis of the China's designing method of cement concrete pavement of military airport(GJB 1278-91), the calculating model and steps of remaining life of cement concrete pavement of military airport with the reversed method brought up by ICAO are shown in this paper. Moreover, some programs were presented to determine the parameters in the model. The remaining life is calculated on the basis of measured data. Through comparing with the historical information on pavement maintaining, it is obtained that the estimation methods can anticipate the remaining life of cement concrete pavement of military airport accurately. The prediction model also could be treated as one part of pavement performance prediction of the military airports pavement management system.
