Ordering Information5.1 The purchaser using this specification shall include thefollowing information:5.1.1 ASTM designation (D4505),5.1.2 Classification type for Retroreflectance (I or II; see4.2),5.1.3 Classi
20、fication class for adhesive (1, 2, or 3; see 4.3),5.1.4 Classification skid resistance level (A or B; see 4.4),5.1.5 Daytime color (see 6.2),5.1.6 Width and length of rolls, and5.1.7 Any additional information.6. Requirements6.1 Physical Requirements:6.1.1 The marking tape shall be flexible and shal
21、l conformto the typical road pavement surface.6.1.2 The marking tape shall adhere to asphalt or portlandcement concrete roadway surfaces when applied according tothe manufacturers recommended procedures on pavementsurfaces having temperatures down to 50 F (10 C).6.2 Color:6.2.1 The white and yellow
22、marking tape shall conform tothe requirements of Specification D6628.6.3 DimensionsThe marking tape as supplied shall be freeof cracks, and have edges true, straight, and unbroken. Theactual width of rolls of preformed marking tape used forstriping shall be no less than the nominal (stated) width an
23、d nomore than18 in. (3 mm) greater than the nominal width. Thelength shall be no less than the length stated.6.4 Retroreflection:6.4.1 The marking tape shall be retroreflective, reflectingwhite or yellow, respectively, and shall be readily visible whenviewed with automobile headlights at night and s
24、hall haveminimum initial reflective values as shown in Table 1 whenmeasured in accordance with the photometric testing proce-dures of Test Method D4061 or E1710.NOTE 1Retroreflectance may be dependent on the direction in whichthe material is manufactured (for example, upweb RLmay differ fromdownweb
25、RL.)The retroreflectance of the marking tape shall be measured inone roll-winding direction and then re-measured in the oppo-site direction. Both measured values shall comply with thestated RLminimum.6.4.2 Reflective values shall be expressed as a coefficient ofretroreflected luminance (RL) in milli
26、candelas per square metreper lux (millicandelas per square foot per footcandle).NOTE 2The values presented for the coefficient of retroreflectedluminance (RL) are presented in SI units, which are the acceptedworldwide norm for expressing this value, rather than in inch-pounds.6.5 AdhesionAsample of
27、marking tape, 1 in. (25.4 mm) inwidth, applied according to the manufacturers recommendedprocedure and tested in accordance with Test Methods D1000,shall have minimum adhesion values as shown in Table 2.6.6 Skid ResistanceSkid resistance shall be tested inaccordance with Test Method E303.NOTE 3For t
28、apes with a surface pattern, results often are quitevariable. These tapes may be tested in a direction parallel to the flow oftraffic and 45 from the direction of traffic, and the results averaged.NOTE 4Skid resistance levels of 45 BPN correspond to tapes havingexposed retroreflective glass beads. H
29、igher levels of skid resistance areachievable with the addition of skid-resistance elements.7. Durability and Wear Resistance7.1 Factors Affecting Durability and Wear Resistance:7.1.1 Features of the pavement marking tape, such asthickness and wear surface material, may affect durability. Ingeneral,
30、 thicker materials wear longer than thinner materials ofthe same composition. Wear surfaces composed of hardermaterials, such as urethanes, may be more durable than thosemade of softer materials like vinyl.7.1.2 Roadway Characteristics Affecting DurabilityRough road surfaces, porous surfaces, and hi
31、gh traffic volumestend to decrease service life of markings. A high percentage oflarge vehicles tends to decrease service life. Encroachment ora lot of vehicles turning on top of the marking decreasesservice life. Techniques and materials used for control of iceand snow also affect durability.TABLE

34、to provide complete, reliable, predictive informa-tion on durability and wear resistance, the user is encouraged toseek information from alternate sources.NOTE 5The National Transportation Product Evaluation Program,administered by AASHTO, publishes data on the durability of manypavement marking tap

37、the roll.9. Storage9.1 StorageThe marking tape as supplied shall have aminimum shelf life of one year from date of purchase whenstored at temperatures under 100 F (38 C).10. Packaging and Marking10.1 The marking tape shall be packaged in rolls and thereshall be no more than three splices per 164 ft

Keywords11.1 pavement marking; pavement marking tape; retrore-flectance; tapeANNEX(Mandatory Information)A1. DISCUSSION OF “30-METRE” GEOMETRYA1.1 The European Committee for Standardization (
39、CEN)originally developed the geometry used in this standard formeasuring the retroreflectance of preformed tape (entranceangle 88.76 and observation angle 1.05). The angles werederived using theoretically typical heights for headlamps anddrivers eyes. These heights were further simplified by assum-i
40、ng a single headlamp is mounted directly under the driverseye (see Fig. A1.1). The geometry is considered a goodapproximation for drivers viewing preformed tape on a flatroad, 30 m ahead of a car.D4505 12 (2017)3ASTM International takes no position respecting the validity of any patent rights assert
