16、Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.14.1.1 Type I (Removable)Marking tapes, after serving theintended limited service life, shall be removable from asphaltor portland cement concrete surfaces at pavement temperature
17、sabove 40 F (4 C) intact or in pieces no less than about 93 in.2(600 cm2) in area, either manually or with a mechanical devicewithout the use of heat, solvents, grinding, or blasting thatwould damage or discolor the pavement so as to leave animpressed traffic lane mark.4.1.2 Type II (Non-Removable)T
18、his type of tape shall notbe required to have removal characteristics as in 4.1.1.NOTE 2Type II tapes are most often used for short-term applicationsin which markings are paved over during successive road constructionoperations.5. Ordering Information5.1 The purchaser using this specification shall
19、include thefollowing information:5.1.1 ASTM designation (D4592),5.1.2 Classification Type (I or II; see 4.1),5.1.3 Daytime color (see 6.3),5.1.4 Width and length of rolls, and5.1.5 Any additional information.6. Requirements6.1 Physical Requirements:6.1.1 The marking tape shall be a reflective film c
20、oated witha pressure-sensitive adhesive with or without a protective liner.6.1.2 The marking tape shall be flexible and shall conformto the typical road pavement surface.6.1.3 The marking tape shall adhere to asphalt or portlandcement concrete roadway surfaces when applied according tothe manufactur
21、ers recommended procedures on pavementsurfaces having temperatures down to 50 F (10 C) at the timeof application.6.1.4 Immediately following application, the tape shall notrequire a cure or set time prior to opening to traffic.6.1.5 The tape as supplied shall be free of cracks, and havetrue, straigh
22、t, and unbroken edges. The actual width of rolls ofpreformed marking tape used for striping shall be no less thanthe nominal (stated) width and no more than18 in. (3 mm)greater than the nominal width. The length shall be no less thanthe stated length.6.2 Retroreflection:6.2.1 The marking tape shall
23、be retroreflective, reflectingwhite or yellow, respectively, and shall be readily visible whenviewed with automobile headlights at night and shall haveminimum reflective values as shown in Table 1 when measuredin accordance with the photometric testing procedures of TestMethod D4061 or E1710.NOTE 3R
24、etroreflectance may be dependent on the direction in whichthe material is manufactured (in other words, upweb RLmay differ fromdownweb RL.)6.2.2 The retroreflectance of the marking tape shall bemeasured in one roll-winding direction and then re-measuredin the opposite direction. Both measured values
25、 shall complywith the stated RLminimum.6.2.3 Reflective values shall be expressed as coefficient ofretroreflected luminance (RL) in millicandelas per square meterper lux (millicandelas per square foot per footcandle).NOTE 4The values presented for the coefficient of retroreflectedluminance (RL) are
26、presented in SI units, which are the acceptedworldwide norm for expressing this value, rather than in inch-pounds.6.3 Color:6.3.1 The white and yellow marking tape shall conform tothe requirements of Specification D6628.6.4 Adhesion:6.4.1 A sample of tape, 1 in. (25.4 mm) in width, appliedaccording
27、to the manufacturers recommended procedure andtested in accordance with Test Methods D1000, shall haveminimum adhesion values as shown in Table 2.6.5 Skid Resistance:6.5.1 The Type I marking tape shall have an averageminimum frictional resistance value of 45 BPN (British Pen-dulum Number) when teste
28、d according to Test Method E303.NOTE 5Skid resistance is not required for Type II non-removabletapes that are typically applied for a short duration and then paved over.NOTE 6Skid resistance levels of 45 BPN correspond to tapes havingexposed retroreflective glass beads. Higher levels of skid resista
29、nce areachievable with the addition of skid-resistant elements.NOTE 7For tapes with a surface pattern, results are often 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.7. Durability and Wear Resist
30、ance7.1 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, thicker materials wear longer than thinner materials ofthe same composition. Wear surfaces composed of hardermaterials,
31、such as urethanes, may be more durable than thosemade of softer materials, like vinyl.7.1.2 Roadway characteristics affect durability. Rough roadsurfaces, porous surfaces, and high traffic volumes tend todecrease service life of markings. A high percentage of largevehicles tends to decrease service
32、life. Locations where ve-hicles encroach or turn on the markings decrease service life.Techniques and materials used for control of ice and snow alsoaffect durability.TABLE 1 Reflectivity Values for Dry SamplesAEntranceAngleObservationAngleMinimum Reflective Value, (RL)White Yellow88.76 1.05 500 300

36、 and 100 F(10 and 38 C).9.

DISCUSSION OF “30-METRE” GEOMETRYX1.1 The European Committee for Standardization (CEN)originally developed the geometry used in this standard formeasuring the retroreflectance of preformed tape (entranceangle 88.76 and observation angle
38、1.05). The angles werederived using theoretically typical heights for headlamps anddrivers eyes. These heights were further simplified by assum-ing a single headlamp is mounted directly under the driverseye (see Fig. X1.1). The geometry is considered a goodapproximation for drivers viewing preformed
