Streets - City of Bartlesville

R&R - is an abbreviation for remove and replace – deep patching. The R&R designation is used
to identify rehabilitation strategies that have additional funds set aside for increased amount of
surface preparation.
Olay - is an abbreviation for overlay.
Rehab Costs – the rehabilitation costs are presented on a per square yard basis for each
pavement type–functional class–rehabilitation activity combination. The rates were developed
using typical national averages for similar activities and then were adjusted for Bartlesville’s
location and unique conditions. The rates do not include any burdens or allowances to cover
costs for traffic control and site preparation, striping and pavement markings, engineering and
inspection, ADA compliance, landscaping, signals or signage upgrades, peripheral concrete
repairs and miscellaneous costs or contingency. Typically these burdens, in addition to City
overhead costs, can add 25 to 35% to the unit rates and overall budgets.
PCI Range - defines the Pavement Condition Index (PCI) range applicable to the rehab selection.
Segments that fall between the Minimum PCI and Breakpoint PCI are funded first in the defined
Rehabilitation Order. Once these are selected, the software recycles through the segments
selecting non-critical streets in order of priority up to the maximum PCI value.
The Minimum PCI value is the lower limit which rehabilitation may be applied, beyond that value,
a heavier rehabilitation is required. The Breakpoint PCI defines the range that if a segment is
deferred, it will drop below the Minimum PCI within one year and thus require a thicker
rehabilitation. The maximum PCI is the condition score where the lighter rehabilitations may be
applied. The combination of these three values establishes a methodology of optimizing
available funding by always selecting critical segments in their need year, and allowing others to
be deferred until they become critical.
Constraint – defines the Load Associated Deducts (LAD) range applicable to the rehab
selection. The LAD identifies streets with potential structural issues that either require a thicker
rehabilitation or increased level of patching and preparation work. Conversely, segments with low
LAD may receive lighter treatments.
Post Rehab Resets Values – Defines key condition values to be applied once the street
segment has been rehabilitated.
Order – defines the order in which rehabilitations are applied. Once combined with the segment
priority, these two factors determine the order in which streets are selected for rehabilitation. The
Priority lists the segments from highest to lowest priority, while the Order defines which
rehabilitations are funded first.
The Rehabilitation Order is based on the incremental cost of deferral – that is, the lower the
Rehabilitation Order, the greater the cost if the rehabilitation is deferred.
