Roadmap Step 9a

Cost-Benefit Value

With limited funding, how do I prioritize my projects?

CBV offers roadway managers a way to prioritize projects while accounting for the variables relevant to you and the realities of traffic, cost and life extension.

CBV =

( Traffic / Constraint Factor ) x ( Life Extension )

( Unit Cost ) x ( PCI )

Two road comparison: Which road should I treat first?

Road 1
Worst First Reconstruction
AADT: 5000 PCI: 30
( 5000AADT / 7CF ) x ( 25Years )

( $39Per SY x 30PCI )
= 15 CBV

Road 2
Pavement Preservation Chip Seal
AADT: 5000 PCI: 75
( 5000AADT / 7CF ) x ( 6Years )

( $2Per SY x 75PCI )
= 29 CBV

CRITICAL CONCEPT

For Equal Traffic, Preservation Has A Higher Benefit.

There are many variations on the CBV formula, each used to prioritize whatever factors are most important to that agency.

Annual Average daily traffic (abbreviated AADT) is traditionally the total volume of vehicle traffic of a highway or road for a year divided by 365 days. AADT is a useful and simple measurement of how busy the road is. Don’t know your AADT? See below for common ranges from the FHWA.

	ARTERIALS				COLLECTORS		LOCAL
	Interstate	Other Freeways & Expressways	Other Principal Arterial	Minor Arterial	Major Collector	Minor Collector	Local
Rural	12,000 - 34,000	4,000 - 18,500	2,000 - 8,500	1,500 - 6,000	300 - 2,600	150 - 1,110	15 - 400
Urban	35,000 - 129,000	13,000 - 55,000	7,000 - 27,000	3,000 - 14,000	1,100 - 6,300	1,100 - 6,300	80 - 700

NOTE: Many agencies learn their AADT using traffic counters, which can be moved to various locations during the year. Vehicle types and amount have a large influence on roadway deterioration, for example 1500 AADT with 25% truck traffic is much more severe than an AADT of 1500 with 5% truck traffic.

Pavement Condition Index (PCI) is one of many scales used to indicate the general condition of a pavement. PCI is evaluated based on inspection and observation and must account for both the severity and extent of pavement distress. Throughout the PPRA site, we’ve used the following scale. Knowing the condition of your network is the first step in improving overall network condition and many manual and automated methods exist. If you’re unsure of your road’s PCI, please visit our photo gallery of roads at varying levels of distress to gain a general idea.

Pavement Rating	PCI
A - Excellent	85-100
B - Good	70-84
C - Fair	55-69
D - Poor	40-54
F - Very Poor	0-39
