  1. D11 - ENGINEERING DIVISION

  2. TRAFFIC STRIPES & TRAFFIC SIGNS VISIBILTY DURABILITY COST

  3. Traffic Signs and Stripes are one of the Most Cost-effective Means of Improving Highway Safety The Cost of Traffic Sign Panels and Stripes is Minimal Compared to the Total Project Cost < 4%

  4. TRAFFIC STRIPES PAINTTOHIGH REFLECTIVE THERMO

  5. PAINT STRIPES • D-11 has 4,000 lane miles • Up until 2010 District 11 used paint stripes • Paint Life Expectancy < 1 Year • To maintain visibility Caltrans MTCE crew had to refresh the paint stripes on a yearly basis • Total Yearly Cost = $3,000,000 million Issues: Safety + Labor Cost + Material Cost

  6. THERMOPLASTIC STRIPES In 2009 we Started Experimenting with THERMOPLASTIC STRIPES HEATED-PLASTIC & REFLECTIVE BEADS • Layer #1 heated thermo, 400-440 degrees • Layer #2 Glass beads on top of the thermo

  7. THERMOPLASTIC STRIPES THERMOPLASTIC CLOSE-UP VIEW

  8. THERMOPLASTIC STRIPES HEATED THERMOPLASTIC TANK BEADS TANK NOZZLES THERMOPLASTIC TRUCK

  9. THERMOPLASTIC STRIPES SPRAY NOZZLES

  10. THERMOPLASTIC STRIPES • D-11 Started Experimenting 2009 • Reflectivity Value: White = 250 Yellow = 150 IN 2010 DISTRICT-11 SWITCHED STRIPES ALL THERMO COST PER YEAR OF SERVICE

  11. HIGH REFLECTIVE THERMOPLASTIC STRIPES

  12. HIGH REFLECTIVE THERMOPLASTIC STRIPES • D-11 Started Experimenting 2011 • Layer #1 Heated Thermoplastic Material • Layer #2 Highly Reflective Glass Beads • Layer #3 Standard Glass Beads • Cost $/LF in 2011 = $0.42 • Cost $/LF in 2014 = $0.32

  13. FINAL PRODUCT CLOSE-UP

  14. COIN (DIME) HIGH REFLECTIVE BEADS STANDARD BEADS DRY BEADS CLOSE-UP

  15. HIGH REFLECTIVE BEADS STANDARD BEADS DRY BEADS CLOSE-UP

  16. FINAL PRODUCT ENHANCED THERMO

  17. RETROREFLECTIVITY IN (MCDM-2LX-1) YELLOW STRIPES 3X RETROREFLECTIVITY WHITE STRIPES RETROREFLECTIVITY COMPARISON

  18. RETROREFLECTIVITY COMPARISON

  19. Standard Thermo VsHigh Performance Thermo HIGH PERFORMANCE THERMOPLASTIC HAS: • ALMOST THE SAME COST • 3X TIMES THE RETROREFLECTIVITY • HIGH VISIBILITY DURING DRY & WET WEATHER IN 2012 D-11 SWITCHED STRIPES TO ALL HIGH REFLECTIVE THERMO DISTRICT-11 IS CURRENTLY USING ENHANCED THERMOPLASTIC ON ALL NEW PROJECTS D11 - STRIPING CONCLUSION

  20. WHAT IS NEXT IN FOR STRIPING?

  21. SIGN SHEETING Reflectivity Durability Cost

  22. RETROREFLECTIVE SHEETING TYPES WHICH TYPE SHOULD WE USE?

  23. Retroreflectivity is defined as the light that returns to the light source RETROREFLECTIVITY

  25. CAR HEADLIGHTS OFF (Location 1)

  26. CAR HEADLIGHTS ON (Location 1)

  27. CAR HEADLIGHTS OFF (Location 2)

  28. CAR HEADLIGHTS ON (Location 2)

  29. CAR HEADLIGHTS OFF (Location 3)

  30. CAR HEADLIGHTS ON (Location 3)

  31. CAR HEADLIGHTS OFF (Location 4)

  32. CAR HEADLIGHTS ON (Location 4)

  33. RETROREFLECTIVITY / WARRANTY

  34. D-11 REPORT

  35. SAVINGS & BENEFITS - TYPE XI • REDUCE INFRASTRUCTURE COST • REDUCE ELECTRICAL ENERGY COST • INCREASE SAFETY • REDUCE MAINTENANCE COST (Bulbs, Copper Theft) IN 2012 D-11 SWITCHED TO TYPE XI SHEETING FOR ALL SIGNS “2015 LIGHTS OUT”

  36. JULY 2014 - TYPE XI SHEETING STATEWIDE STANDARD FOR GUIDE SIGNS TYPE XI SHEETING A STATEWIDE STANDARD

  37. OTHERS REASONS FOR BETTER & BRIGHTER SIGNING & STRIPING MATERIALS

  38. MUTCD MINIMUM MAINTAINED RETROREFLECTIVITY LEVELS MANUAL ON UNIFORM TRAFFIC CONTROL DEVICES REPLACE NON-COMPLIANT WARNING AND REGULATORY SIGNS 2015 REPLACE GUIDANCE AND STREET NAME SIGNS 2018

  39. NOW MORE THAN EVER WE NEED BRIGHTER SIGNING & STRIPING ELDERLY BABY BOOMERS POPULATION IS GROWING

  40. GROWING DRIVING POPULATION

  41. CHOOSE WISELY
