WHEN TO SEAL AGAIN
The aim of this bulletin is to provide a guide based on proven practice, which will enable an individual road controlling authority to develop a long term policy for resurfacing and to choose the appropriate work for the current year. Resurfacing policy is an essential component of long term maintenance. It is the responsibility of roading authorities to obtain adequate technical support in order to formulate a policy which as a minimum: (1) defines the worst acceptable condition for each type of road in the system; (2) describes resurfacing methods that are acceptable for each road type; (3) provides a statement of the funding restraints which must be considered when deciding on the economic level of resealing activity from year to year. Putting the policy into practice requires forward programming and a technical input into the selection of lengths for resurfacing. An inventory of roads is essential and will reduce the number of detailed inspections that are required. The many factors which need to be evaluated when considering the choice of available treatments and the economic aspects for inclusion in a programme are discussed. A set of photographiuc examples of road surfaces nearing the end of their life is appended together with an example of reseal criteria for New Zealand state highways. (TRRL)
