State of the Pavement Reports
The Virginia Department of Transportation (VDOT) is responsible for more than 125,000 lane miles of roadway.
Virginia’s current highway network is the result of more than 100 years of investment in infrastructure that provides for the economic activities and the mobility of people and goods throughout the commonwealth.
Preserving this investment is a core function of VDOT.
These reports describe the condition and ride quality on Virginia’s pavements based on data collected, processed and analyzed by VDOT. They also provide trend analysis over the last five years.
The information in these reports is used to understand variations in pavement condition and ride quality by pavement type, highway system, maintenance district and county.

Pavement and Quality Data
Chapter 290 of the 2013 Acts of Assembly (HB 1885) requires VDOT to determine a quantitative rating on the pavement condition and ride quality of every highway in the primary and secondary state highway systems at least every five years. VDOT is required to post these ratings on its website, organized by transportation district, and update the information quarterly. The following information is provided in compliance with this requirement.
The pavement condition data and ride quality data are summarized by homogeneous pavement segments. Location details for each section include district, county (Maintenance jurisdiction), route system, route type, route number, direction of travel, begin mile point, and end mile point. The pavement condition is indicated by Critical Condition Index (CCI), and ride quality by International Roughness Index (IRI). The date data was captured is also included in these tables.
Pavement Condition is captured in terms of CCI on a scale of 0-100. A CCI value of 100 represents a pavement with no visible distress, while a pavement with a CCI value of 0 indicates a pavement in heavily distressed condition.
Pavement roughness is generally defined as an expression of the aggregation of irregularities in the pavement surface that adversely affect the quality of ride of a vehicle and thus the user. Ride quality data is captured in terms of International Roughness Index (IRI) in inches/mile. The typical IRI value of a new pavement is about 40-60 inches/mile and higher values of IRI indicate rougher ride quality.
