2200-1 Section 2201
RETROREFLECTIVE SHEETING 2201.1 DESCRIPTION This specification covers Type I and all Types of Hi gh Intensity retroreflective sheeting. This includes both non-exposed glass bead lens and microprismatic sheeting. 2201.2 REQUIREMENTS
a.General. Provide retroreflective sheeting that complies with ASTM D 4956. The type to be provided will be shown in the Contract Documents. Type s and classes are as defined in ASTM D 4956.
b.Conformable Retroreflective Sheeting. Provide High Intensity retroreflective sheeting that has a conformable aluminum foil backing with an aggressive pr essure sensitive adhesive. Th is material is designed for application to moderately rough or por ous metal, wood or masonry surfaces. Pr ovide material that complies with ASTM D 4956 with the followi ng exceptions and additions:
1.Conformable aluminum backing thickness – 0.005 inches to 0.010 inches. (2) Follow all manufacturers’ recommendations for application procedures and temperatures. 2201.3 MANUFACTURER WARRANTY The following warranty conditio ns apply only to the retroref lective sheeting manufacturer. Provide a product warranty for a minimum period of 10 years on all Types of High Intensity retroreflective sheeting for placement on permanent signing. Failure to comply with th is warranty may be cause for removal from the prequalified list. The High Intensity retroreflective sheeting warranty must comply with the following requirements and obligations: Certification: Submit with each lot or shipment, a certification which states that the material supplied is subject to and complies with the requirements. In clude in the certification, the manufacturer’s office, address, phone number and the contact for potential clai ms under the provisions of this warranty. Provide documentation as to which signs were fabricated from each lot. Field Performance: Field Performance applies to retroreflective sheeting applied to sign blank materials or overlaid on existing signs. The field performance oblig ation period begins with the date of erection. The sheeting is considered unsatisfactory if it has deteriorated due to natural causes to the extent that the sign is ineffective for its intended purpose when viewed from a moving vehicle under normal day and night driving conditions or shows any of the following defects: Cracking discernible with the unaided eye from a driver’s position at a distance of 50 feet or greater from the sign: Scaling, pitting, orange peel, delamination, edge lifting or curling; Peeling in excess of 3/8 inch; Shrinkage in excess of 3/16 inch total per yard of sheeting width; Fading or loss of color to the extent that retroreflective sheeting color fails to comply with subsection 2201.2a. , or; Loss of retroreflectivity reducing the coefficient of retroreflection as measured by a retroreflectometer to less than th e minimum specified in Table 12 of ASTM D 4956 at 0.2° observation and -4° entrance angles. Make all measurements after cleaning the sign. Defective Material Replacement: When traffic signs with High Intensity sheeting fail to comply with the field performance requirements, re-sheet or replace the signs at no cost to KDOT for materials and labor. Employ a contractor qualified by KDOT to perform signing work. Inst all highway signs, as shown in the Contract Documents and the MUTCD and provide proper traffic control. Replace all defective materi al within 60 days after written notificat ion by KDOT. Signs not corrected within 60 days, will be removed and replaced by KDOT. Signs removed by KDOT will be placed in storage for inspections by the manufacturer, and the manufacturer will be billed for all costs of replacement of the sheeting.
