Vehicle-pavement interaction defines the relationship between a vehicle on a pavement, and the pavement. Pavement unevenness causes vehicles to generate dynamic tyre loads. The pavement roughness level, vehicle type, vehicle components, and vehicle speed affect these tyre loads. Application of these loads to the pavement cause transient pavement responses that differ from static pavement response to static loads. Incorporation of these dynamic tyre loads into pavement design is a complicated mathematical process. A guideline based on existing pavement analysis procedures was developed to simplify this process. In this paper a short background to vehicle-pavement interaction is provided, followed by the guideline and an example of applying the guideline. The objective of the paper is to expose the pavement engineer to a practical guideline for incorporation of vehicle-pavement interaction issues into pavement design. Application of the guidelines indicated that use of dynamic tyre load populations rather than equivalent static loads in pavement response analyses can cause significantly different pavement responses.
