Abstract
AbstractThe new draft AASHTO standard practice PP70-10 and PP69-10 are promising to change the landscape of rut measurement. PP70-10 specifies the technical requirements for transverse profiling and PP69-10 defines multiple parameters such as percent deformation and rut cross-sectional area to characterize a rut. Per PP70-10, an inspection device should cover at least 4.0 m (13 ft) transverse width in order to cover the full lane under vehicle wandering. However, for many existing transverse profilers, it is challenging to identify the lane markings from the raw images in a consistent manner. This deficiency would prevent these systems from accurately calculating PP69-10-based rut attributes. In this study, with the field data collected in Arkansas national highway systems (NHS) using an automated system called PaveVision3D Ultra, the impact of lane offsets on PP69-10-based rut attributes is investigated. The rut attributes calculated with programs embedded in the system, where accurate lane locations are...
