This specification and accompanying guidance notes set out the requirements for the adjustment of service covers necessary before asphaltic concrete paving, after a pavement reseal, settlement of the pavement adjacent to service covers, or settlement of the covers themselves. This specification will be withdrawn in 2011 as it has been replaced by HM15 service covers. However, if TNZ C8 is referred to in existing contract documents then you may continue to use it. Alternatively you could use MR09 Pre-surfacing repairs if you plan to include all of the following specifications in a single surfacing contract: C4, C5, C6, C7 and C8.
