As of December 31, 2012, DelDOT maintains 1,572 bridges in Delaware. 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, 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.

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

11. 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

12. 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)

*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.

19. 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)

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

21. Outreach “What We Do Series” Community outreach Education

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

23. 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
