Expected service life of wearing courses
As part of its 2012 to 2015 strategic plan the World Road Association (PIARC) determined the need to identify and review approaches taken in assessing the service life of wearing courses. This report reviews the different approaches taken by road authorities to determine the service life of wearing courses. The aim is to understand why they are replaced and identify the factors that affect decision-making. The service life of a wearing course depends on several factors such as the type of wearing [...]
