Statewide Pavement Condition
The performance measure being used for the pavement component of our Preserve Infrastructure Goal is our annual statewide condition report.
This graphic shows the percent of centerline miles rated in good, fair & poor condition. This is being calculated using the national FHWA scale for pavement roughness based on the reported 0.1 mile IRI data collected on all State roads (5,865 miles). (Note: condition data was not collected in 2013 & 2016 – these values are interpolated)
This performance measure is also being used for the annual GASB34 reporting.
High Volume System Condition
One of the primary performance measures being used for the pavement management program is our Statewide High Volume System condition report. Our pavement management strategy is to maintain a status quo condition level for this system of Interstate, National Highway System, and other high volume roads with over 1,000 AADT (3,915 miles).
This graphic shows the historical and forecasted condition levels. The historical condition is calculated from our collected 0.1 mile IRI data. The forecasted condition is from our pavement management system with our expected funding levels to maintain a status quo condition level - currently at 210 million $/year.
Low Volume System Condition
The other primary performance measures being used for the pavement management program is our Statewide Low Volume System condition report. Our pavement management strategy is to improve the condition level for this system of low volume roads with less than 1,000 AADT (1,950 miles).
This graphic shows the historical and forecasted condition levels. The historical condition is calculated from our collected 0.1 mile IRI data. The forecasted condition is from our pavement management system with our expected funding levels from the recent gas tax increase being used for this system - currently at 40 million $/year.
This new performance measure was developed to improve of the Surface Area measure. This is based on each surfacing project providing a benefit to the pavement life. Assuming all of our pavements lose 1 year of life each year- to maintain a sustainable condition consistent with our pavement management strategy – our projects should replace an equivalent amount of pavement life.
This is calculated by multiplying each project’s surface area of surfacing by the expected years of benefit / the system surface area. Values less than 1 would indicate an expected decline in condition, while values in excess of 1 would indicate an expected improvement in condition.
This is a forward looking measure to be used to with our proposed list of projects. (1 surface area = 1 lane mile = 5,280’ x 12’)
This performance measure was developed for the High Volume system to provide a perspective on how much surfacing work was being planned and constructed each year. The goal was based on an 11 year average treatment cycle. A 4 year average is being used for reporting due to the significant difference each year based on the types of projects.

** 2018, 2019, 2020 Funding not fully programmed
The pie charts below illustrate some differences between high and low volume system surface areas by region.
High Volume Surface Area by Region
Low Volume Surface Area by Region
Region allocations are updated annually and provided in the spring. The 2017 condition data will be used for making 2020 recommendations. For year to year consistency it was agreed to limit adjustments to less than 2 percent per year. Separate allocations are provided for the High Volume system Federal funds, and the Low Volume system State funds.
Program Funding and Splits
Charts below show statewide funding and condition, and region splits over time for both high volume and low volume systems.

Condition Data & Maps
Condition data is collected annually and reported in 0.1 mile intervals. The 2017 data was collected in both directions. The 2018 data will be collected in only the positive direction.
