Abstract
An aircraft pavement strength rating system has been internationally adopted since 1981. Since that time, aircraft tyre pressures and wheel loads have increased significantly and an increase in shear-related surface distress has been reported. The current strength rating system focuses on protection of the subgrade. It also includes a tyre pressure limit intended to protect stress-susceptible surfaces. However, the shear stresses in the surface layer have been shown to be a function of both the tyre pressure and the individual wheel load. A modification to the current aircraft pavement strength rating system is recommended. The proposed modification replaces the current tyre pressure rating with a classification number that reflects the contribution of both tyre pressure and wheel load to surface layer shear stress. Guidance is also provided on the selection of a surface rating and the granting of approval for usage by aircraft with more demanding wheel load and tyre pressure combinations. It is also recommended that efforts to include shear-related surface failure modes into routine pavement design tools be given high priority, as this will allow a more rational approach to surface rating selection. © 2017 Informa UK Limited, trading as Taylor & Francis Group
