When two separate sections of the same highway are resealed, structured road markings in the in-between 'infill' section are often left untouched. This can cause ‘markings continuity’ issues. The newly resealed section will feature fresh markings while the infill section will feature older markings.
Having to return to the same site a year or more later to re-do infill road markings can be costly, operationally inefficient and disruptive to motorists. In this paper, WSP senior asset manager Obinna Akaa and colleagues present a method that roading owners can use to tactically and cost-effectively manage renewal of road markings at infill sites - in a way that better preserves the asset, minimises disruption and does not compromise safety.
The optimal asset management approach is to renew infill markings in the same construction year that nearby sections have been resealed - provided certain criteria are met, including infill length, reseal year, road marking condition and remaining life, material and installation costs, installation timeframe, traffic management and customer disruption. An example scenario is presented to help readers understand the infill method's real-world application.
