A key factor in the performance of bituminous seals, prior to needing maintenance or replacement, is the aging characteristics of the seal itself. The ability to assess the age of in situ binders through a swift and simple technique is therefore advantageous in supporting maintenance and rehabilitation strategies across Australia’s sealed road network.
Good quality asset management records may not always be available, and therefore the budgeting and planning of future works can be challenging. It is crucial that appropriate maintenance and rehabilitation programs are upported and that the correct tools and methodologies are used to help prevent serious failures of roads or erratic reallocation of resources.
