The paper presents data from a number of sites in the Middle Eastwhere detailed pavement evaluation has been performed; generallyutilising the FWD, DCP, coring/pitting and, sometimes high-speedground radar, to determine pavement layer thickness and condition.This data has enabled both empirical and mechanistic design methodologiesto be used and compared. Emphasis is made to one particular projectin Qatar, where over 3000 FWD test points were analysed and relationshipsbetween deflection levels, stiffnesses, predicted lives and ModifiedStructural Number were developed. Data from the detailed assessmentof a heavily trafficked pavement in the United Arab Emirates (U.A.E)is also given to illustrate the importance of material characterisationwhen developing maintenance measures. The results from the FWDwere used in conjunction with performance related laboratory testresults, predominantly using the Nottingham Asphalt Tester, NAT.The NAT enables stiffness, deformation resistance and fatiguecracking resistance properties of bituminous materials to be determined.
