Topics Pavement Management Preservation Methodologies Microsurfacing – why, when, where? Quantities and Prices Materials and Construction Outreach Future

Pavement Management Maintain over 13,731 lane miles (4,378 centerline miles) including suburban streets 89% of roadways in state Centralized network evaluations “Van tour” of candidate locations Includes: Pavement Management, Materials, Construction, Maintenance, Support Sections (Bike/Ped, R/R, Design, Planning)

Pavement Management (cont) Centralized project designs (statewide) (4) Maintenance Districts receive some funds for: Open-Ended Patching/Paving Contracts Surface Treatment materials Microsurfacing Contracts (candidate locations are approved by Pavement Management) Pavement condition = state bond rating

There are 81 bridges that are owned and maintained by others, such as municipalities or railroads. The bridges range in size and type from a simple pipe culvert, to draw bridges, to the new Indian River Inlet Bridge. All bridges undergo routine bridge inspections in compliance with federal standards to ensure the bridge's integrity and the public safety. Deficiencies found during inspections are monitored at a frequency that is appropriate, with the intention to systematically rehabilitate or replace them to bring them into compliance with current standards. Currently, Delaware has 4,378.02 centerline miles of roads, valued at over $5 billion, and the Delaware Department of Transportation is responsible for maintaining 89% of them. The national average of state-maintained roads is approximately 20%. When it comes to maintaining this valuable highway infrastructure, the old adage that "an ounce of prevention is worth a pound of cure" is definitely true. Timely maintenance extends the life of existing roads and bridges and saves as much as $3-4 for every dollar of preventive maintenance we spend. *Appraisal of the Nation's Bridges (NBI Coding Guide) http://deldot.gov/dashboard/conditions.shtml?road=all&county=SW[12/30/2013 11:28:03 AM]

Preservation Methodologies Mill-and-Fill In-Place Recycling/Reclamation Overlays Structural Thin Lifts Surface Treatments (DelDOT forces) Microsurfacing

Pavement Preservation Costs Treatment Type Cost per Centerline Mile Surface Treatment* * Utilize Department forces for placement $10,000 Microsurfacing $50,000 Surface Treatment to Asphalt Conversion $225,000 Asphalt Overlay $300,000 Mill + Asphalt Overlay $500,000 FDR + Asphalt Overlay $370,000

Microsurfacing – Why? Effective preservation tool (at the right time, on the right road) Limited funds Legislative/community concerns

Microsurfacing – When? Where? Placed in 5 – 7 year timeframe after previous pavement placement Structurally sound pavement Patch and crack seal in advance (typically previous year) Typically lower ADT roadways (~ < 10,000 ADT) Higher than surface treatment roadways

Microsurfacing - Misc Have a ton pay item as well (for rut filling) Use in Amish communities Debonding issues over thermoplastic striping/symbols Make sure roadway is clean prior to placement (debonding)

Microsurfacing Design Program Year Centerline Miles Estimated Cost FY 2009 43.10 $ 2,155,000.00 FY 2010 127.52 $ 7,493,485.00 FY 2011 107.00 $ 8,398,985.00 FY 2012 188.00 $ 11,280,000.00 FY 2013 145.78 $ 8,746,800.00 FY 2014 4.85* $ 363,750.00 *Due to halt of spending in 2012, back log from FY 2012 and FY 2013 rolled into FY 2014, causing the extremely low length of new approved micro locations. In FY 2014 we still had active micro contracts with about 200 miles of micro to do.

Materials Typical Mix Design Aggregate (sub 3/8”) Mineral Filler Field Additive (cement) Binder (CSS 1h - PM) Use asphalt cost adjustment

Construction Equipment calibration Test strips 50oF and rising; not below 32oF for 24 hours Multiple lifts may be required based upon field conditions (SY vs. tonnage pay item)

Construction (cont) Clean surface Return to traffic: 15 – 60 minutes Mud, vegetation, oil, debris Striping/symbols RPM’s Return to traffic: 15 – 60 minutes

Outreach “What We Do Series” Community outreach Education Description Video DelDOT website http://deldot.gov/newsy/whatwedo/microsurfacing/index.shtml

Outreach (cont) Industry Partners Other agencies: Spoke with asphalt paving association early Few placement contractors in the area Other agencies: Schools Natural Resources

Future Uncertain funding levels Pavements must be maintained (or at least preserved) VMT will probably not decrease Preservation methods will continue to be an option including microsurfacing
