Pavement Preservation

A paving machine lays down a new layer of pavement on the motor road.
The steps involved in the chip and fog seal process include: cleaning and prepping, chip seal application and curing, vacuuming to reduce loose gravel, fog sealing and striping, and repeating in the next 3-5 mile section.

The Blue Ridge Parkway manages 554 miles of paved road, including the iconic 469-mile-long main parkway road. All pavement deteriorates over time. The parkway has many demands on its road surface. It is a heavily traveled, high elevation road subject to seasonal freeze-thaw cycles in winter and solar radiation in summer.

Funding for road systems in national parks comes from national gas tax dollars through the Federal Lands Transportation Program (FLTP). The parkway receives approximately $7 to $10 million per year for paving, bridge, and tunnel repair projects through a competitive process with other national parks in the southeast region of the National Park Service. However, the parkway has about $500 million in deferred maintenance costs. Approximately 90% of these costs are due to maintenance needed on paved roads in the park.

What is Pavement Preservation?

In order to more strategically invest funding for road projects, the parkway, along with parks throughout the National Park Service, has identified road sections eligible for a strategy known as pavement preservation. Pavement preservation applies a new road surface to sections in good condition, helping slow deterioration and allowing the road maintenance budgets to go further.

2020 Pavement Preservation Projects

Approximately 80 miles of parkway qualify for pavement preservation treatment this year beginning in May 2020, and continuing through November 2020. Work will be on hold during the high traffic month of October.

These sections of parkway are scheduled for pavement preservation work in 2020:

  • Milepost 0 to 27, Northern Terminus to Whetstone Ridge (27 miles)
  • Milepost 37 to 65, Irish Gap to James River Area (28 miles)
  • Milepost 175 to 200, Mabry Mill to Fancy Gap area (25 miles)

Other sections that are not suitable for pavement preservation will be prioritized and targeted for full repaving as funds allow.

What to Expect

  • Work zones will be managed using one-lane traffic control with flaggers and a pilot vehicle under reduced speed limits.
  • Observe reduced speed limits in work zones, 24 hours a day, 7 days a week to maintain safe operations and allow for proper curing of pavement
  • Anticipate loose gravel on the road surface during pavement curing times.
  • Bicyclists and motorcyclists are asked to exercise extreme caution in project areas as loose gravel on top of the paved surface could result in loss of control.
  • The Blue Ridge Parkway Road Closure Map will be updated at least weekly with current information about rolling work zones.
