FLEXIBLE PAVEMENTS. SINO-BRITISH HIGHWAYS AND URBAN TRAFFIC CONFERENCE. PAPERS PRESENTED AT THE CONFERENCE HELD IN BEIJING 17TH-22ND NOVEMBER 1986

This paper describes the design of those flexible pavements that comprise bitminously bound materials constructed on an unbound granular or cement-bound foundation over natural subgrade material. Details are given of: (1) the different layers of pavement materials; (2) the properties of bituminous materials, including dynamic stiffness, resistance to deformation, resistance to fatigue cracking, durability, workability, and skid resistance; (3) empirical and analytical methods of pavement design. Semi-empirical design methods, of the type used in the United Kingdom provide a reliable method of pavement design where enough experience from full-scale trials is available; without such experience, a more fundamental approach to the design of flexible pavements is needed. The mechanical properties of bituminous mixes, made with local materials, can be determined, and appropriate pavement materials can be selected in this way. These mechanical properties can then be used in analytical design methods to produce suitable pavement designs. However, reference to empirical methods and engineering judgement are still essential, because the analytical design methods have not yet been fully developed. (TRRL)
