1 2007 PAVEMENT MARKING ACTIVITIES AND PERFORMANCE Operations Division April 25, 2008

2 2Operations Division PAVEMENT MARKING SUMMARY Customer Satisfaction Customers are positive but not completely satisfied Continue to investigate new materials and methods to improve visibility, especially at night and wet weather conditions Pavement Marking Tech Memo Compliance: The Tech Memo expired in December 2007 New Tech Memo issued soon 99.7% compliant

3 April 25, Operations Division PAVEMENT MARKING SUMMARY (Continued) Pavement Marking Performance: Pavement Marking Inventory System Proposed plan for 08 measuring Central Business Activities: Material Costs are rising sharply Central Business generating savings through efficiencies and identified best practices

4 April 25, Operations Division PAVEMENT MARKINGS OUTLINE Importance of Pavement Markings Importance of Pavement Markings Pavement Marking Policy, Measures, Targets Pavement Marking Policy, Measures, Targets Research Research Central Business Activities Central Business Activities Construction Activities Construction Activities

5 April 25, Operations Division IMPORTANCE OF PAVEMENT MARKINGS Market research Market research Supports TZD by improving traffic safety Supports TZD by improving traffic safety Driving population is aging Driving population is aging Recent research Recent research

6 April 25, Operations Division MARKET RESEARCH Pavement Marking Customer Satisfaction Rating Scale 1-10 From Omnibus Survey Survey was not done in 2007 Neutral Positive 7 Acceptable = 8

7 April 25, Operations Division PAVEMENT MARKINGS POLICY, MEASURES, TARGETS Policy: Policy: Provide appropriate pavement markings to provide presence and retro-reflectivity (RR) on all highways 365 days a year. Provide appropriate pavement markings to provide presence and retro-reflectivity (RR) on all highways 365 days a year. Measures: Measures: Percent of system compliant with Tech Memo requirements Percent of system compliant with Tech Memo requirements Minimum Retro-reflectivity ( MCD/m2/lux ) Minimum Retro-reflectivity ( MCD/m2/lux ) Cost and productivity Cost and productivity Customer Satisfaction Customer Satisfaction Targets: Targets: 100 Percent compliant with TM by Dec Percent compliant with TM by Dec Percent line miles meeting minimum RR or scheduled for replacement 100 Percent line miles meeting minimum RR or scheduled for replacement

8 April 25, Operations Division Technical Memorandum T-03 Mn/DOT Policy for Pavement Marking Operations Technical Memorandum T-03 Mn/DOT Policy for Pavement Marking Operations Issued May 2, 2003 and expired December 31, Issued May 2, 2003 and expired December 31, New Technical memorandum to be issued soon. New Technical memorandum to be issued soon. With New Construction and Retrofit should have substantial compliance by 2008 With New Construction and Retrofit should have substantial compliance by 2008 PAVEMENT MARKING TECH MEMO

9 April 25, Operations Division NON-COMPLIANT ROADWAYS Need 25 Miles to Epoxy, 73 Miles to CL Tape/EL Epoxy 0.3% of 36,900 Line Miles State-wide

10 April 25, Operations Division NON - COMPLIANT ROADWAYS Need 12 Miles to Epoxy, 35 Miles to CL Tape/EL Epoxy 0.3% of 16,773 CL Miles State-wide Non-Compliant

11 April 25, Operations Division PAVEMENT MARKING RETRO-REFLECTIVITY The ability of the pavement markings to reflective light back to its source. 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. 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 Wear (vehicles, weather) and Tear (snow plows) reduces Pavement Marking Retro-reflectivity mcd/m 2 /lux Retro-reflectivity Comparison

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

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

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

15 April 25, Operations Division RETRO-REFLECTOMETER READING PLAN Improve District confidence in data and prove effectiveness of equipment and procedures. Improve District confidence in data and prove effectiveness of equipment and procedures. Establish a shared state-wide pavement marking inventory system. Establish a shared state-wide pavement marking inventory system. Resolve installation issue prior to payment. Resolve installation issue prior to payment.

16 April 25, Operations Division PROPOSED STATE-WIDE PAVEMENT MARKING INVENTORY SYSTEM (PMIS) July 2008 Contract Completion. July 2008 Contract Completion. May 7, 2008 Statewide Training and District Feedback. May 7, 2008 Statewide Training and District Feedback.

17 April 25, Operations Division PMIS CAPABILITIES & BENEFITS Inventory of pavement markings in the State Inventory of pavement markings in the State Easy access to retro-reflectivity data state-wide Easy access to installation history state- wide Quick assessments of pavement markings state-wide Correlation between planned striping and planned construction activities

18 April 25, Operations Division PAVEMENT MARKING RESEARCH PROJECTS Wet Reflective Markings Wider Markings Rubber Snow Plow Blades Late Season/Cold Weather Markings Rumble StripEs

19 April 25, Operations Division CENTRAL STRIPING BUSINESS LINE MAINTENANCE Saved $2,234,089 in 2007 Saved $2,234,089 in to 2007 outsourcing pavement marking maintenance in Metro area to increase the efficiency of in-house crews 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. Material Costs increasing due to increase in fuel costs.
