Streets - City of Bartlesville

That is, as each roadway approaches the steep part of its deterioration curve, apply a remedy that
extends the pavement life - at a minimum cost, thereby avoiding costly heavy overlays and
reconstruction. Thus, the goal of a pavement information management system is to identify the optimal
level of funding, timing, and renewal strategy agencies should adopt to keep their roadway network at a
satisfactory level of service. Figure 3 illustrates the concept of extending pavement life through the
application of timely rehabilitation activities.

Ideally, the lower limit of the target zone shown in Figure 3 would have a minimum value of 70 – that is to
keep as many streets as possible requiring a thin overlay or less. The upper limit would tend to fall close
to upper range of the very good category – that is a pavement condition score of 80.
Other functions of a pavement management system include assessing effectiveness of maintenance
activities and new technologies; storing historical data and images.
