7.3.3 Sprayed Seals

A sprayed seal can be expected to have a lifespan of between 5 to 15 years, depending on many factors such as seal type, traffic, climate and location.

Resealing an existing sprayed seal surface prematurely should be avoided where possible, as there is an increased risk that the binder in the underlying sprayed seal will still be soft and could be prone to embedment from the aggregate in the new seal. This could subsequently lead to the reseal flushing or bleeding.
