Pavement performance data, in terms of measured FWD deflection, was collected from the LTPP/LTPPM sites and used for the modelling of structural deterioration of flexible asphalt and sealed unbound granular pavements at a network level. The strength deterioration analysis was undertaken in terms of the modified structural number (SNC) as it was considered to represent the overall strength of the pavement/subgrade system. Structural deterioration models were developed for asphalt and sealed unbound granular pavements with independent variables, pavement age (AGE), design life (DL) and Thornthwaite Moisture Index (TMI).
