The advent of automated vehicles (AVs) creates an essential need for upgrading conventional road infrastructure and necessitates the study of AVs deployment impacts on pavement performance. One of the most significant differences between AVs and non-AVs is the lateral wandering pattern of the vehicles. The automated steering control system of AVs would allow having more control over the lateral wandering, which can influence the pavement rutting performance. There is as yet no consensus on how AVs and non-AVs will interact in the future. They may use shared travel lanes (i.e., integrated scenario) with different AVs’ penetration rates, or it is possible to use a dedicated lane (i.e., segregated scenario) for AVs. This paper evaluates the impacts of different wander distributions of AVs on pavement rutting performance, considering both segregated and integrated cases with different AVs penetration rates and lane width scenarios. For this purpose, a finite element model was developed using ABAQUS software. The preliminary results of rutting simulation show that the maximum rutting depth in a lane with 100% AVs (i.e., dedicated lane) with zero and uniform wander distribution is greater than the rutting induced by non-AVs following a normal load distribution. Furthermore, the comparison between rutting depths in different lane widths reveals that the total rutting depth of the pavement would remarkably increase by reducing the lane width. Since we are in the process of assessing the remaining simulations, the final results will be included in the full paper.

The Implication of Automated Vehicles Deployment on Pavement Rutting Performance

Welcome to the International Airfield and Highway Pavements Conference of the Transportation & Development Institute (T&DI) of ASCE. This international conference will provide an unrivaled chance to interact and exchange information with worldwide leaders in the fields of highway and airport pavements, as well as airport safety technologies.

This conference will bring together designers, project/construction managers, academics, and contractors from around the world to discuss the state-of-the-art implementation, construction, design, in airfield and highway pavements.
