For asphalt pavements, VDOT calculates two different condition indices from the distress information that is collected, and then combines them into a single condition value.

•Load-Related Distress Rating (LDR) is calculated from load-related distresses, such as fatigue cracking in the wheel path (VDOT, 2006). •The Non-Load Related Distress rating (NDR) is calculated from non-load-related distresses, such as construction deficiencies, bleeding, etc. (VDOT, 2006).

The Critical Condition Index (CCI) is then calculated as the lower of the NDR and LDR. The CCI values range from 1 to 100 and the roads are given an overall rating using the ranges shown in Table 1.

VDOT Pavement Conditions Scale

Table 1. Pavement Condition Definitions (VDOT, 2006)

Index Scale (CCI) Pavement Condition Likelihood of Corrective Action

90 and Above Excellent Very Unlikely

70-89 Good Unlikely

60-69 Fair Possibly

50-59 Poor Likely

49 and Below Very Poor Very Likely

Snow Removal and Snowzilla Slideshow

VDOT in Northern Virginia

Fairfax, Prince William, Loudoun, and Arlington counties(Arlington maintains own secondary roads)

Total lane miles: 13,016 (4,800 lane miles Fairfax County)

Interstate: 726 lane miles(Includes Express Lanes)

Primary: 1,729 lane miles

Secondary: 10,561 lane miles(318 miles gravel roads)(16,000 neighborhood streets)

24 commuter lots

VDOT Roads – Northern Virginia

Crews work interstates, major roads and main roads in subdivisions concurrently.

Interstates 66/95/395/495 made passable, then bare pavement

High-volume routes (1, 7, 28, 50, etc.) made passable, then bare pavement

Subdivisions(Main roads) made passable, then remaining streets and cul-de-sacs.

Additional priorities:•Shoulders•Moving snow where there is no storage (I-95/395 HOV, construction areas)•12,000 park-and-ride spaces along I-95, I-66

Subdivisions are divided into 650 snow maps (350 in Fairfax)Updated annually to ensure all state-maintained roads are included.

How subdivisions are assigned and plowed

• Plows staged in subdivisions when 2”+ forecasted• Plowing begins with 2” of snow on the ground• Main thoroughfares are priority and plowed repeatedly in storm• Crews then work streets, cul-de-sacs

Drivers:• Assigned up to five maps each• Report back after at least one pass on each road

One of 650 snow maps assigned to plow drivers. Hot spots are identified by superintendents and added annually.

Neighborhood Snow Maps

Subdivisions and low-volume roads

• Goal: Reach the most residents as quickly as possible• One pass for a typical storm; major storms require multiple

passes and heavy equipment• Hills, curves, intersections sanded for traction• Driveways, sidewalks, trails, hydrants: drivers asked to be

mindful but blocking is often an unintended consequence.

What does “passable” mean?

An 8- to 10-foot path cleared for emergency vehicle access, and drivable with extreme caution. The road remains snow-packed and rutted. The path will not be curb-to-curb or bare pavement.

Completing Subdivisions

• Monitors: VDOT staff drive routes for quality control

• Maps are considered complete when a driver reports to area headquarters and monitors have spot-checked

• Once subdivisions are passable,the call center logs inquiries for the field to revisit

• AVL Plow tracking site can help verify that passes were made;

provides data for inquiries

So what did it look like?

So what happens next?

Post-Storm ActivitiesPotholes•Crews have filled 10,000+ potholes since Jan. 1•Using “Pothole Killers” as well as traditional methods•Report locations at www.virginiadot.org or 800-FOR-ROAD
