Pavement Preservation Program Emily McGraw, PE February 23 and 24, 2015 – NCDOT & CAPA Workshop

Applying the RIGHT Treatment …to the RIGHT Road What is Pavement Preservation? …at the RIGHT Time

Why Pavement Preservation? Cost Effective Approach Planned vs. Reactive Strategy Up to a 6 to 1 savings ratio vs. “worst first” Good Pavements stay good Prevents failures before they occur Results in smoother, safer roads Reduces vehicle operations costs Improved highway/user satisfaction Reflects favorably on agency and paving industry 3

Why is Preservation important in NC? 6

What does North Carolina’s System Look Like? Approximately 60,000 miles on Secondary Paved System 54% have Plant Mix (32,000 miles) 44% have Asphalt Surface Treatment (26,300) System size second only to Texas 7

Pavement Preservation Program SL , Section 34.11(f-m) Establishes Pavement Preservation Program Defines eligible and ineligible treatments Directs DOT to establish an account Defines outsourcing targets through 2018 Directs DOT to increase use of paving industry Defines minimum treatments (4300 lane miles) Defines reporting requirements 9

Eligible Activities – Section 34.11(f) 1.Chip seals, slurry seals, fog seals, sand seals, scrub seals, and cape seals 2.Microsurfacing 3.Profile milling not covered by resurfacing 4.Asphalt rejuvenators 5.Open graded asphalt friction course 6.Overlays less than 1000 feet in length 7.Diamond Grinding 8.Joint Sealing 9.Dowel bar retrofit 10.Partial-depth or full-depth repairs and reclamations 11.Ultra-thin whitetopping 12.Thin lift and sand asphalt overlays 10

Pavement Preservation Outsourcing Funds allocated for pavement preservation should meet the following targets: Mileage requirement:4300 lane miles Budget:$ 65 Million FY – 20%outsourcing ($13 Million requirement, $ 2.8 Million under contract to date) FY – 30% outsourcing FY – 55% outsourcing FY – 80% outsourcing 11

Pavement Preservation Outsourcing Funds allocated for pavement preservation should meet the following targets: FY lane miles paved by June 30, lane miles paved by the end of the 2015 paving season FY lane miles paved by June 30,

Outsourcing – Section 34.11(j) Increase Use of Paving Industry General Assembly intent that DOT work cooperatively with paving industry DOT is directed to conduct workshops/training to encourage privatization and reduce amount of pavement preservation activities conducted by state forces 13

Department Activities Established Internal Transition Team Contract Development and Specifications Industry Outreach and Education Contract Inspection Data Tracking State Force Transition 15

Contract Development and Specifications New AST specifications – January 2015 Collaborating with Associations Divisions reported 60 anticipated preservation contracts this fiscal year 16

Industry Outreach and Education Highway Divisions have identified potential contractors Department personnel have on-going meetings with associations Department is hosting a Chip Seal Best Practice course on February 25, 2015 Department has contracted with a local engineering firm to develop a NC Chip Seal Manual and Training 17

Inspection DOT is formalizing materials sampling for chip seal operations Will develop Contractor and Inspection Certification Programs DOT will analyze and report all state force and contract preservation funds 18 Data Tracking

State Force Transition DOT will systematically reduce its use of personnel placing chips seals DOT anticipates utilizing 10 of the 14 Division Bituminous crews during the 2015 paving season Experienced DOT staff will assist in development and inspection of contracts 19
