Pavement Management Update - PW415
DISCUSSION
Today's increasing budget constraints requires cities to perform more work with
less money. Historically, the emphasis for growing communities has been
building roads and implementing preventative maintenance due to the relatively
new network system, but as street networks age, the new focus is on maintaining
and preserving existing pavement surfaces. This shift has resulted in three main
types of pavement treatment options:
· Preventive Maintenance: This item includes filling potholes, sealing cracks
and seal coating.
Rehabilitation: Preformed to con'ect deficiencies that occur in pavements
such as extensive cracking and potholing. This type of maintenance includes
mill and overlays.
· Reconstructive: This item is preformed when corrective maintenance is no
longer appropriate.
All types of pavement treatment are needed in a comprehensive pavement
management program. However, emphasizing preventive maintenance will
significantly delay a pavement from requiring rehabilitation or reconstruction
maintenance. Pavement management is completing the right repair on the right
segment of roadway at the right time.
A pavement management program is a systematic approach to using a series of
pavement treatment options over time. One treatment at the right time will
improve the quality of the pavement surface and extend the pavement life, but the
true benefits of the pavement management program are realized when there is a
consistent schedule.
An effective pavement management program integrates many preventative
maintenance strategies, rehabilitation and reconstruction treatments. The goal of
such a program is to extend pavement life and enhance system-wide performance
in a cost-effective and efficient way. Studies show that preventative maintenance

is six to ten times more cost effective then a minimal maintenance program with
only some rehabilitation and reconstruction maintenance strategies used.
Benefits of pavement prevention include improved customer service and
substantial life cycle cost savings. Treatments are especially cost effective when
applied earlier in the life of a pavement. In addition, by extending the life of a
pavement section, it allows the agency to even out its maintenance budget from
year to year.
Critical elements of a successful pavement management program are:
1. Surveying of the pavement network on a consistent basis.
2. Determining a rating for each pavement segment.
3. Determining if any maintenance should be implemented and timing of the
maintenance.
4. Budgeting for pavement work.
5. Implementing the pavement treatment.
6. Observing the performance.
Keys to a successful pavement management program include education, timing
and funding. To implement a pavement management program effectively, all
decision makers should be educated about pavement management, why it is
needed, and why it should be a priority. It should be stressed that it is more
economical to preserve pavements in good condition then it is to replace them
when they wear out. The general public also should be educated about pavement
preservation and the cost effectiveness of having a constant pavement
management program. Pavement treatments must be applied in time to preserve
the structure of pavement. Also, an effective pavement management program
requires adequate funding. Criteria needs to be established for the selection of
pavements to have work preformed, and this policy must be enforced.
Staff will be providing a brief review of the City's current pavement management
system. This review will include the City's current 5-year street improvement
plan and identify some future needs.
