Development of mechanistic flexible pavement design method for Malaysian conditions / Ahmad Kamil Arshad

Malaysia currently utilises an empirically-based pavement design procedure which is adopted from the AASHTO 1972 Design Guide. Elsewhere, pavement design approach is shifting towards mechanistic-based procedures that are based on the mechanics of materials. The purpose of this study is to develop a...

Field work data derived from the Falling Weight Deflectometer tests were compared to the values obtained from laboratory testing of asphaltic concrete, base and sub-base materials and were found to be consistent for those sites where the thickness of the pavement materials were consistent and uniformly layered. 2009 Thesis NonPeerReviewed text en https://ir.uitm.edu.my/id/eprint/5506/2/5506.pdf Development of mechanistic flexible pavement design method for Malaysian conditions / Ahmad Kamil Arshad.
