What? Preparation work is the work that needs to be performed prior to the application of any treatment. It is important that areas of severe damage are isolated and repaired before any preventative or rehabilitative treatments are applied. Preparation work may also entail the removal of thermal plastic striping, street sweeping, or grinding.

Why? If isolated areas are not addressed before the application of a preventative maintenance, such as a slurry seal, the benefits of the preventative maintenance treatment may not be maximized. The unrepaired section will deteriorate sooner than other areas. In addition, if the pavement is not properly cleaned and swept, the new treatment may not bond properly.

When? When there are isolated areas of failure, prep work is necessary in order to maximize the benefits of any maintenance or rehabilitation treatment.
