(PREFORMED) THERMOPLASTIC Typical Dimensions: Can be ordered in 5 gallon bucket or 55 gallon drum, preformed sheets size varies but usually come in 2 ft. x 2ft. sections. Estimated Cost: $14 - $20 / sq. ft. for preform thermoplastic (installed, typically used for mural-like installations, such as decorative crosswalks). Overview: A durable heat-applied material often used for pavement markings (bike lane markings, etc.). Demo (1 day - 1 month)

Pilot (1 month - 1 year)

F Interim (1 - 5 years)

Recommended Applications and Installation ɖBikeways: ɖ Use for bike lane or sharrow markings, per MUTCD standards. ɖPedestrian ɖ Crossings: Use retroreflective preformed thermoplastic strips for crosswalk striping and nonretroreflective colored sections for decorative crosswalks, as per FHWA guidance. Preformed thermoplastic decorative crosswalk materials shall be supplied in patterns and colors as per FHWA guidance. Preformed thermoplastic for decorative crosswalks shall contain anti-skid elements in the intermix and on the surface. ɖPlazas ɖ / Curb Extensions: Use as a surface treatment for decorative plaza / public space element (not recommended for full surface coverage). Tips and Considerations »» Requires professional installation. »» Sheets of interconnected preformed thermoplastic material are easily lifted and positioned onto an asphalt or concrete surface for application with propane heat torches or infrared heaters. »» Heat application typically required to set; not easily removed. »» Moderate degree of flexibility in color and design, though installation cost will vary based on design complexity (intricacy of design chosen, number of non-primary colors chosen, time required to install (etc.).
