A new approach to making decisions about the type of pavement to be adopted

Increasing load intensities and increasing traffic volumes are driving the need to reassess the type of pavements being constructed. Because individual pavement elements have different finite lives, some of which can be very short with increasing load intensity, all pavements need frequent interventions to achieve their service lives. With low load intensities and low traffic volumes, these interventions (frequently enrichments and reseals) are not difficult to manage, subject to budget availability. However, intervention costs escalate with increasing traffic, and not only strain future budgets but can also significantly increase user costs, disruption and delay. This paper describes the consequences of increasing traffic and load intensities on pavement performance; the effect on intervention costs and whole-of-life costs; and proposals to provide a system that adequately generates and assesses the practical alternatives.
