7. PAVEMENT MARKINGS POLICY, MEASURES, TARGETS
Provide appropriate pavement markings to provide presence and retro-reflectivity (RR) on all highways 365 days a year.
Measures:
Percent of system compliant with Tech Memo requirements
Minimum Retro-reflectivity ( MCD/m2/lux )
Cost and productivity
Customer Satisfaction
Targets:
100 Percent compliant with TM by Dec 2008
100 Percent line miles meeting minimum RR or scheduled for replacement

8. PAVEMENT MARKING TECH MEMO
Technical Memorandum T-03 “Mn/DOT Policy for Pavement Marking Operations”
Issued May 2, 2003 and expired December 31, 2007.
New Technical memorandum to be issued soon.
With New Construction and Retrofit should have substantial compliance by 2008

11. PAVEMENT MARKING RETRO-REFLECTIVITY
The ability of the pavement markings to reflective light back to its source.
Headlights bounce off of tiny glass beads directly back to the driver instead of scattering.
Wear (vehicles, weather) and Tear (snow plows) reduces Pavement Marking Retro-reflectivity

12. 2007 RETRO-REFLECTIVITY TOTAL READINGS
6,465 Total Line Miles read in 2007
April 25, 2008
Operations Division

13. RETRO-REFLECTIVITY ISSUES
Concentrating more on markings with suspected deficiencies.
Incomplete and uneven coverage of projects and striping crews.
Increase in Preventative Maintenance hampering performance
Crack sealing and patching over markings
Marking durability poor on chip seals
Chip Seal markings that look good are still measuring low
April 25, 2008
Operations Division

14. RETRO-REFLECTIVITY PLAN
Sampling plan to measure the health of the state-wide pavement marking system.
Increase the use of Handheld readings on new projects and 2L2W roads.
Timely reporting from contractors and Mn/DOT crews.
Researching solutions to preventative maintenance issues including literature review.
State-wide Pavement Marking Inventory System.
April 25, 2008
Operations Division

15. RETRO-REFLECTOMETER READING PLAN
Improve District confidence in data and prove effectiveness of equipment and procedures.
Establish a shared state-wide pavement marking inventory system.
Resolve installation issue prior to payment.

19. CENTRAL STRIPING BUSINESS LINE MAINTENANCE
Saved $2,234,089 in 2007
2005 to 2007 outsourcing pavement marking maintenance in Metro area to increase the efficiency of in-house crews.
Material Costs increasing due to increase in fuel costs.
The price is going up even though labor costs are going down due to increase efficiency.

Operations Division

20. CENTRAL STRIPING BUSINESS LINE MAINTENANCE
Material cost reduction
Started in 2003
Reduced line thickness for liquid markings from 15 to 12 mils.
Reduced glass beads in epoxy from 30 lbs/gal to 15 lbs/gal.
Latex Performance
Performing similarly at
12 and 15 mils.
