9 Quick audience poll… What best represents your current markings materials mix? 100% Thermoplastic 75% Thermo 50% Thermo 25% Thermo 100% Paint or Other Copyright © 2014 Professional Pavement Products, Inc. All rights reserved.

10 Material Basics of Thermoplastic  Granular or block form  Heated to a liquid state  Extrusion, ribbon, or spray systems  Mechanical bond and/or heat fusion  Cools from liquid state to solid state  Durable reflective pavement marking Copyright © 2014 Professional Pavement Products, Inc. All rights reserved.

11 o White Titanium Dioxide o Yellow Lead or Organic o Hydrocarbon o Alkyd o Calcium Carbonate o Various Types and Sizes Pigment Color Opacity Resin Adhesive Cohesive Filler Adds Body Glass Beads Retroreflectivity Four Primary Components There is no Liquid in Thermo – 100% Solids ! Liquidity comes from the heat Copyright © 2014 Professional Pavement Products, Inc. All rights reserved.

12 A Closer Look at Resins ALKYD Made from wood-derived resins, a renewable natural resource  Higher resistance to cracking*  Ability to be applied directly following paving operations  Impervious to petroleum  Best for intersections  More durable HYDROCARBON Made from petroleum derived resins  Best used in long-line applications vs. detail work  Slightly less heat stable  Less sensitive to changes in application properties  Cost effected by oil prices Copyright © 2014 Professional Pavement Products, Inc.

24 Quick audience poll… Which application method do you currently use the most? Extrusion Ribbon Spray Not currently using Thermo Don’t know Copyright © 2014 Professional Pavement Products, Inc. All rights reserved.

25 Surface Preparation Ensure surface is free of dirt, dust and other contaminants. Remove poorly adhered existing markings or curing compound. Verify Pavement is Free of Moisture – Rain Forecast, Sprinklers Timer, Moisture Check, etc. Check that Ambient and Surface Temps are at 50⁰ & rising. Spray Primer on Surface (as needed) Copyright © 2014 Professional Pavement Products, Inc. All rights reserved.

26 Thermo Application  Apply primer if applicable  Preheat material to 400⁰ - 440⁰ F  Apply material to thickness and width specified  Immediately apply glass beads at the appropriate rate  Protect the line until solidified Copyright © 2014 Professional Pavement Products, Inc. All rights reserved.

27 Preformed Thermoplastic Low start - up costs Color change Low skill requirement Less ambient temperature constraints Fast single application Danger working with direct fire High labor factor Material temperature sensitivity Higher material costs PROs Cons Copyright © 2014 Professional Pavement Products, Inc. All rights reserved.

28 Thermo Do(s) & Don’t(s)  DO NOT apply on shoulder or travel lane joints  DO ensure proper formulation is used  DO NOT mix Alkyd and Hydrocarbon thermoplastic in application equipment  DO ensure pavement is clean, dust free and dry  DO ensure poorly adhering existing markings or curing compounds are removed (LNX8)  DO ensure surface temps are 50⁰ F and rising  DO ensure air temperature is 50⁰ F and rising  DO ensure usage of a primer that is approved by the thermoplastic manufacturer Copyright © 2014 Professional Pavement Products, Inc. All rights reserved.

29 Thermo Do(s) & Don’t(s)  DO ensure that glass beads are properly applied immediately after thermoplastic  Beads should anchor at 55-60% embedment  DO NOT hold material above 450⁰ for more than 4 hours  Total heating time should not exceed 6 hours  DO NOT exceed 150 mil thickness in one application  DO use cold or iced water to treat skin in contact with hot thermoplastic  DO NOT attempt to remove thermoplastic from skin (seek medical attention) Copyright © 2014 Professional Pavement Products, Inc.

33 Troubleshooting Thermo… Proper Application Applied Straight Has sharp edge Correct Color, Width, Thickness, Bonding No Adhesion, Bulges at Start 1. Material temperature too low 2. Road too gritty 3. Marking speed too fast 4. Road too cold Bubbles in Line 1. Moisture or solvent trapped in line 2. Material is overheated Roughened, Pitted Line 1. Foreign objects in line 2. Foreign objects caught in die 3. Overheating forms crust Copyright © 2014 Professional Pavement Products, Inc. All rights reserved.

34 Troubleshooting Thermo… Proper Application Applied Straight Has sharp edge Correct Color, Width, Thickness, Bonding Crumbly Edges; Line Gaps 1. Material too cool 2. Material Too thin 3. Application Speed too fast Line Swollen; Skewed, Rounded Start 1. Material too hot Wavy Line 1. Strong road surface camber 2. Surface undulations 3. Poor operator direction Copyright © 2014 Professional Pavement Products, Inc. All rights reserved.

35 Troubleshooting Thermo… Line Cracks 1. Pavement is cracked (doesn’t affect durability) 2. Too cold 3. Temperature stress from overheating 4. Too thin Crumbly Edges; Rough Surface 1. Material temperature too low 2. Moisture in Road 3. Overheated or scorched material Jagged Endings, Drops within Gaps 1. Die not closing properly 2. Foreign objects caught in die Side Shadows 1. Heavily undulated surface 2. Die not riding evenly on substrate Copyright © 2014 Professional Pavement Products, Inc. All rights reserved.

36 Troubleshooting Thermo… Spray Application Proper Application Excessive Overspray 1. Too much atomizing pressure 2. Air leaking thru blow-back spray line Hesitation at Start 1. Moisture or air in spray line 2. Material too hot 3. Material too cold Lumps in Line 1. Material is to cool – comes out in globs Copyright © 2014 Professional Pavement Products, Inc.

39 Retro-what!?!?!?! RETROREFLECTIVITY Ability of an object ( ex. Stop sign ) to redirect light back to its source ( ex. A car ’ s headlights )

40 Why is Retroreflectivity Important? DAYTIME Many cues available Driver task relatively easy NIGHTTIME Few cues visible Task more difficult Retroreflectivity is NECESSARY!! Copyright © 2014 Professional Pavement Products, Inc. All rights reserved.

41 What Sources Provide Retroreflectivity? Light on microprismatic surfaces reflects on 3 mirrored surfaces Light on embedded glass beads bends, reflects, and then bends again Microprismatic Sheeting, RRPMs Copyright © 2014 Professional Pavement Products, Inc. All rights reserved.

42 Pavement Marking Retroreflectivity 60% Embedment  Binding Material  Pavement Surface  A C E A.Light comes from source B.Light bends (refracts) at point of entry of glass bead C.Light reflects off back of glass bead taking the binding material’s color with it D.Light bends (refracts ) again at point of exit of glass bead E.Light returns to original source B D Copyright © 2014 Professional Pavement Products, Inc.
