RATIONAL PAVEMENT DESIGN: THE DEVELOPMENT OF NEW PRACTICES FROM EXPERIENCES IN MAINLY HOT ARID REGIONS
Experience in the Arabian peninsula has shown that many roads constructed a decade or more ago have continued to perform well despite their use by volumes of heavy traffic far in excess of their design value. It was suspected that established empirical design procedures were not truly applicable to the design of pavements on strong subgrades which were required to sustain a large number of repetitions of very heavy axle loadings, and that adoption of such methods might lead to unnecessarily costly construction. Following a literature search, engineers found that the mechanistic method (which requires as inputs the elastic and strength parameters of all the material in the proposed pavement and subgrade) appeared to exhibit all the desired qualities. Advances have now been made in the development of the mechanistic method to a stage where it may be used with confidence in the design of pavements in the United Arab Emirates. The author explains the method with the help of case histories.
