2. 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%

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

20. HIGH PERFORMANCE THERMOPLASTIC HAS: DISTRICT-11 IS CURRENTLY USING ENHANCED THERMOPLASTIC ON ALL NEW PROJECTS D11 - STRIPING CONCLUSION Standard Thermo Vs High Performance Thermo 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 IN 2012 D-11 SWITCHED STRIPES TO ALL HIGH REFLECTIVE THERMO
