Streets - City of Bartlesville

2.2 NETWORK PRESENT CONDITION
Figure 7, presented below shows distribution of pavement condition for the paved roadway network in the
City of Bartlesville on a 0 to 100 scale, 0 being worst and 100 being best condition. The average PCI for
the network at the time of survey was 65, and is currently approximately a 64. While direct comparisons
to other agencies is difficult due to variances in ratings systems, overall, Bartlesville can be considered
average among agencies recently surveyed by IMS.
Figure 7 –Roadway Network Present Status
In comparison to the City’s 2006 ratings, the current network average PCI is similar in nature, but there is
not an exact comparison between the two. Between the 2006 survey and now, the operating software
changed the way the data is managed and the PCI established. The former condition score had all inputs
designed as deducts from a perfect score of 100, roughness, structural strength and the surface
distresses were all reduced to a 0 to 10 score, assigned a weighting factor and then deducted from 100 to
arrive at the PCI score. Under the current program, roughness was measured as its own Index, along
with the surface distresses, no deflection data was collected. A variance of 10 to 15 points between
measurements on any particular roadway is not uncommon. The distribution of pavement quality is
similar between the two rating systems in that they are both skewed to the right with the majority of
streets rated as 60 or above with few streets rated below 20.
The current PCI distribution is reflective of a relatively moderately aged network that has had reasonable
maintenance efforts over time however it also indicates many of the streets are approaching the timing
where heavier overlays and reconstruction may be required to extend service life.
