The new MPQ should be included inth the replacement contract. Generally reseals have a life of 10 - 16 years though some surfacings such as texturising seals and voidfills are used either as a preparatory treatment or to extend the life of the existing surfacing and have a much shorter life span. The expected life of the surfacing is influenced by the underlying pavement structure, however a road suffering deformation requiring frequent repairs will usually undergo resurfacing at shorter intervals. The expected life for different surfacing types and traffic conditions are summarised in Table 6.1.2.2a above, while the length of resealing undertaken in recent years is shown in Figure 6.1.8a below. 30 September 2014 Page 43 of Section 1
