Section III-307 - Minimum Standards for Preformed Plastic Pavement Marking TapeA. General. Preformed plastic pavement marking tape shall be approved products listed on Q PL 64 and shall comply with ASTM D 4505 Type I, Type I-High Performance (as specified below) or Type V, except as modified herein. The marking tape shall be Grade A, B, C, D, or E. The type and color shall be in accordance with the plans and the Manual on Uniform Traffic Control Devices (MUTCD).B. Thickness. All preformed plastic pavement marking tape shall have a minimum overall thickness of 0.060 inches (1.5 mm) when tested without the adhesive.C. Friction Resistance. The surface of the Type I preformed plastic pavement marking tape shall provide a minimum frictional resistance value of 35 British Polish Number (BPN) when tested according to ASTM E 303. The surface of the Type I-High Performance and Type V preformed plastic pavement marking tape shall provide a minimum frictional resistance value of 45 BPN when tested according to ASTM E 303, except values for the Type V are calculated by averaging values taken at downweb and at a 45 degrees angle from downweb.D. Retro Reflective Requirements. The preformed plastic pavement marking tape shall have the minimum specific luminance values shown in Table 1015-10 when measured in accordance with ASTM D 4061.

Type | Observation Angle, degrees | Entrance Angle, degrees | Specific Luminance (mcd/sqm/lx) White Yellow |
I | 0.2 1.0 | 86 86.5 | 500 300 | 400 175 |
I-High Performance | 0.2 1.0 | 86 86.5 | 700 400 | 560 225 |
V | 0.2 1.0 | 86 86.5 | 1100 700 | 800 500 |
E. Durability Requirements. The Type I-High Performance preformed plastic pavement marking tape shall show no appreciable fading, lifting or shrinkage for at least 12 months after placement when placed in accordance with the manufacturer's recommended procedures on pavement surfaces having a daily traffic count not to exceed 15,000 ADT per lane. 1. The Type V preformed plastic pavement marking tape shall show no appreciable fading, lifting or shrinkage for at least four years after placement for longitudinal lines and at least two years after placement for symbols and legends.2. The Type V preformed plastic pavement marking tape shall also retain the following reflectance values for at least four years after placement for longitudinal lines and at least two years after placement for symbols and legends. Observation Angle, degrees | Entrance Angle, degrees | Specific Luminance (mcd/sqm/lx) White Yellow |
1.0 | 86.5 | 100 | 100 |
F. Plastic Pavement Marking Tape Guaranty (Type I-High Performance and Type V). If the plastic pavement marking tape fails to comply with the performance and durability requirements of Subsection 1015.11 (§307) within 12 months for Type I-High Performance and four years for Type V, the manufacturer shall replace the plastic pavement marking material at no cost to the department.La.
