Biennial Report on Maintenance Requirements

G.S. 136-44.3 Requires NCDOT to:

  • Establish Performance Standards
  • Project an annual cost to meet and sustain the performance

standards for routine maintenance and operations

  • Develop a cost for Pavement and Bridge Preservation
  • Develop a cost for Pavement and Bridge Rehabilitation
  • Project System Condition at optimal funding for 7 years

SLIDE 3
  • 79,185 road miles
  • 160,630 paved lane miles
  • 4,592 miles of unpaved roads
  • 18,205 structures
  • 88.1 M square feet bridge deck area
  • 8,900 signals

North Carolina Freight Movement

In 2007:

  • 281 million tons moved across N.C.

annually

  • 770,000 tons per day

In 2030:

  • Expect more than 324 million tons to

be moved across N.C. annually

  • 15% increase

Performance Based Management

Benefits include:

  • Moving towards uniformly constructed, maintained and
  • perated Highway System
  • Data driving decision making
  • Increased focus on preventive maintenance
  • Targeting Level Of Service by system
  • Highest and best use of resources
  • Challenging and rewarding workplace
  • Accountability
slide-10
SLIDE 10

Performance Measures

Sets clearly defined outcomes such as:

  • No unsealed cracks in pavements
  • Bridge decks rating in good condition
  • No pipes blocked or damaged
  • Pavement markings visible at night

Since 2008:

  • Reviewed targets to ensure accuracy
  • Made modifications as necessary
  • Simplified and streamlined
