Performance-based pavement design: a case study

Vehicle operating costs (VOC's) which account for over 85 per cent of transport costs on a heavily trafficked road are profoundly influenced by pavement condition. The rougher the road the more is the VOC and as the pavement condition approaches the terminal state, the VOC's surge up, hiking the transport costs. This kind of relation between the VOC's and pavement condition brings out the need to check the deterioration of pavements to below the critical level by strengthening overlays at appropriate times and not permitting the pavement condition to recede to the terminal state. This paper demonstrates a performance-based approach of optimal pavement design. In the case study that is presented, several pavement alternatives (of various compositions) are considered and the progression of pavement roughness with traffic and age is examined using pavement deterioration models in the HDM-4. Overlays are commissioned whenever the roughness reached the critical level in each case and further overlays are also considered on the same basis. After estimating the vehicles operating costs, life-cycle cost analysis is carried out for the alternatives to pick up the one with the highest overall benefits suiting the investment options.
