Abstract
To provide a totally comprehensive Europe-wide cost benefit analysis for the adoption of long-life pavements (LLPs) is not a straightforward task. This paper proposes a methodology to compare the results of the cost benefit assessment of determinate life pavements with that of LLPs. This approach is relevant but nevertheless raises certain issues such as the determination of residual life.
Existing models which are available for the economic evaluation of LLPs are presented but none of them take into account all of the significant parameters, for example, environmental costs. In addition, other parameters may be difficult to assess with sufficient accuracy due to the specific behaviour of LLPs such as the lack of deterioration in the structural layers.
An example whole life cost analysis of a part of the UK network suggests the large potential benefits to be obtained from the adoption of the LLP design principles on a heavily trafficked road network even before considering the potential environmental benefits of such an approach.
