32 FIELD STUDIES IN INDIANA Paint, Thermoplastic, and Epoxy Paint SR 28 SR38 Test Installation (Initial Test): West of Frankfort, East of I lane divided highway. Only painted edge line rumble strips were installed on existing eastbound rumbles for both yellow and white paint. Site was also use to test standard INDOT bead mix and 3M wet-dry bead mix. New Installation: East of Antioch, West of Kirkland. 2 Lane Rural Route. Complete installation on new asphalt including centerline joint adhesive, fog seal, and painted centerline rumble stripes. US 120 New Installation: East of US13. Complete installation on new asphalt including centerline joint adhesive, fog seal, and painted centerline rumble stripes. Centerline joint and fog seal were used. US231 Retrofit: South of Lafayette, north of I-74. Installation on existing asphalt leaving existing RPMs in place. Edge line as well as Centerline painted rumbles were installed. Milling was performed on existing asphalt, and both the center and edge lines were joint sealed as necessary and fog sealed. SR26 New Installation: Between SR29 and US31, west of Kokomo. 2 Lane Rural Route. Installation on new mill and paved asphalt. Epoxy paint on center and edge line with one thermoplastic test strip.

Only painted edge line rumble strips were installed on existing eastbound rumbles for both yellow and white paint. Site was also use to test standard INDOT bead mix and 3M wet-dry bead mix. New Installation: East of Antioch, West of Kirkland. 2 Lane Rural Route. Complete installation on new asphalt including centerline #5: SR26 joint adhesive, fog seal, and painted centerline rumble stripes. (Edge/Center Lines) US 120 New Installation: East of US13. Complete installation on new asphalt including centerline joint adhesive, fog seal, and painted centerline rumble stripes. Centerline joint and fog seal were used. US231 Retrofit: South of Lafayette, north of I-74. Installation on existing asphalt leaving existing RPMs in place. Edge line as well as Centerline painted rumbles were installed. Milling was performed on existing asphalt, and both the center and edge lines were joint sealed as necessary and fog sealed. SR26 New Installation: Between SR29 and US31, west of Kokomo. 2 Lane Rural Route. Installation on new mill and paved asphalt. Thermoplastic was used instead of paint at the centerline.

34 PAINTED CENTERLINE Installation Observations Paint Appears to have de bonded on fogseal RPM Lens Removed

35 PAINTED EDGELINE Installation Observations Old Edgeline Removed Fog Sealant Used on Edgeline New Edgeline in Rumbles

36 MATERIAL SELECTION FOR MARKINGS Paint, Thermoplastic, and Epoxy Trials Use design manual guidance for material selection defined in Indiana Design Manual Chapter 76 Thermoplastic

37 MATERIAL SELECTION FOR MARKINGS Thermoplastic on SR 26 Consider quality control in pre phase planning Speed and methods of application Material temperature/application Pitting in Rumble Move Even Application Higher Speed Lower Pressure Application Lower Speed Higher Pressure Application

38 MAINTENANCE OF TRAFFIC Grinding/Milling/Sealing/Marking/Lens Removal: Lafayette Create traffic control plan based on site specific conditions. Use IMUTCD, Standard Specifications and Standard Drawings for guidance to maintain moving traffic. Include language regarding flagging of traffic and for equipment protection in each step of the installation and operation process. Understand that each process varies in speed (exceeding walking speed) and restricts lane usage. Understand that rumbles move traffic towards operations.
