An asset management methodology for value-for-money reinstatement of pavement markings

Abstract

The reinstatement of pavement markings after resurfacing will typically entail like-for-like re-marking of the resealed road sections. However, there are cases where sections in between planned reseal (infills) may be left untouched or are not required in the renewal contract irrespective of the service life and condition of the infill markings. This gives room for poor marking continuity and reduction of the markings service level. As the asset management of long-life high-performance markings includes a duty of care around cost-effectively realising value from planned maintenance, there is a need to consider infills when reinstating long-life markings on resurfaced road sections. This paper presents a method for determining infill sites for cost-effective renewal to forestall returning to the same road in the future, thereby managing customer delay and realising cost savings without compromising road safety. The method considers tactical assessment merits and life-cycle costs to demonstrate its suitability to solving the problem. Various marking reinstatement cases were investigated where the results showed method applicability and highlighted sensitivities to re-mark length and installation time. The method supports the asset owner/manager to plan pavement markings renewals at the tactical/section level and could benefit from further studies that consider more complex scenarios, extended variables and uncertainties.
