Thirty-four of the 40 agencies that have responded to date report that they have established pavement preventive maintenance programs. Half of those programs have existed for more than 10 years, and only seven are less than 3 years old.

Dedicated funding is available for pavement preventive maintenance activities in 28 of the reporting agencies. Agencies in 25 States have established guidelines for pavement preventive maintenance activities, and another 4 agencies are in the process of developing guidelines.
Most agencies try to apply pavement treatments while the pavement is in good or fair condition.
Half of the agencies, however, report that they are applying treatments to pavements in poor condition. The number of pavement preservation strategies used in each State varies widely, from none to 16. Money spent on pavement preservation is well spent.
