Structural evaluation of thinly-surfaced granular pavements

The aim of this research programme was to develop a pavement evaluation procedure for thinly surfaced dressed granular pavements. Although well advanced and rational pavement evaluation techniques for bituminous pavements are now being introduced, pavement evaluation procedures adopted for overseas roads are still largely based on empirical data and pavement strength is related to the maximum transient deflection of the pavement under a standard wheel load The maximum transient deflection is merely a general indicator of the pavement performance and incapable of identifying the weaknesses, whether they are due to the pavement layers or its foundation.
