Abstract : This report describes and discusses the concept of reliability in pavement design. Some designers refer rather to 'design confidence level' or even in an older sense to increased design safety factors. The report covers the improvement of pavement design and the fact that 'pavement management systems' methodologies provide an ideal framework for considering reliability. Consideration is given to three techniques for reducing variability in design: (1) improved quality control, (2) use of design confidence level, and (3) the concept of reliability level. The study shows that pioneers in realistic use of reliability in design include Kher, Lemer, Moavenzadeh and Darter. The philosophy of determining and corroborating reliability levels is discussed and recommendations for work to advance the state-of-the-art are presented.
