The paper describes advanced analysis procedures to evaluate pavement layers` interface bonding conditions using non-destructive techniques and Falling Weight Deflectometer surveys. The pavement mechanical properties in terms of the layers` moduli were evaluated under the impact of a dynamic loading by using the Falling Weight Deflectometer (FWD) surveys. The results revealed that the use of the advanced analysis procedures allows for more accurate calculation of the pavement mechanical properties and thus more accurate analysis of the pavement`s structure life. This is one of the advantages of the advanced analysis procedure since the restriction imposed on the conventional back calculation methods that full bonding between the individual layers exist, has been relaxed.
