Abstract:
A method for adapting existing pavement thickness design curves and formulas for "special" concretes is presented. The need for doing this is discussed; i.e., special concretes made, for example, with fiber reinforcement or high-range water reducers have material properties (specifically changed fatigue endurance and the effects of maturity) which are different from the long-assumed properties that "normal concretes" possess and upon which current design curves are based. Without making these adaptions, wasteful over-design or failures from underdesign can occur. An example is given
