1、Designation: D4505 12Standard Specification forPreformed Retroreflective Pavement Marking Tape forExtended Service Life1This standard is issued under the fixed designation D4505; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the

2、year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers white or yellow preformedretroreflective pavement marking tape, that when applied to

3、 aroad surface, will provide a service life normally greater thanone year depending on wear and durability factors.1.2 The preformed retroreflective pavement tape is suitablefor longitudinal markings and transverse markings includingword/symbol markings. It is designed to be a pavementmarking with e

4、xtended service life.1.3 The values stated in inchpound units are to beregarded as the standard except where noted in the document.The values given in parentheses are mathematical conversionsto SI units that are provided for information only and are notconsidered standard.2.

Ordering Information5.1 The purchaser using this

17、 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 Classification 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.

18、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 shall conformto the typical road pavement surface.6.1.2 The marking tape shall adhere to asphalt or portlandcement concrete roadway surfaces w

19、hen applied according tothe manufacturers recommended procedures on pavementsurfaces having temperatures down to 50F (10C).6.2 Color:6.2.1 The white and yellow marking tape shall conform tothe requirements of Specification D6628.6.3 DimensionsThe marking tape as supplied shall be freeof cracks, and

20、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 and 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 ma

21、rking tape shall be retroreflective, reflectingwhite or yellow, respectively, and shall be readily visible whenviewed with automobile headlights at night and shall haveminimum initial reflective values as shown in Table 1 whenmeasured in accordance with the photometric testing proce-dures of Test Me

22、thod D4061 or E1710.NOTE 1Retroreflectance may be dependent on the direction in whichthe material is manufactured (for example, upweb RLmay differ fromdownweb RL.)The retroreflectance of the marking tape shall be measured inone roll-winding direction and then re-measured in the oppo-site direction.

23、Both measured values shall comply with thestated RLminimum.6.4.2 Reflective values shall be expressed as a coefficient ofretroreflected luminance (RL) in millicandelas per square metreper lux (millicandelas per square foot per footcandle).6.4.2.1 DiscussionThe values presented for the coefficientof

24、retroreflected luminance (RL) are presented in SI units,which are the accepted worldwide norm for expressing thisvalue, rather than in inch-pounds.6.5 AdhesionAsample of marking tape, 1 in. (25.4 mm) inwidth, applied according to the manufacturers recommendedprocedure and tested in accordance with T

25、est 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 2For tapes with a surface pattern, results often are quitevariable. These tapes may be tested in a direction parallel to the flow oftraf

26、fic and 45 from the direction of traffic, and the results averaged.NOTE 3Skid resistance levels of 45BPN correspond to tapes havingexposed retroreflective glass beads. Higher levels of skid resistance areachievable with the addition of skid-resistance elements.7. Durability and Wear Resistance7.1 Fa

27、ctors 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, such as ure

28、thanes, may be more durable than thosemade of softer materials like vinyl.7.1.2 Roadway characteristics affect durabilityRoughroad surfaces, porous surfaces and high traffic volumes tend todecrease service life of markings. A high percentage of largevehicles tend to decrease service life. Encroachme

29、nt or a lot ofvehicles turning on top of the marking decreases service life.Techniques and materials used for control of ice and snow alsoaffect durability.7.1.3 Tapes that are inlaid into the road surface by groovingor hot rolling generally are more durable than the same tapesoverlaid on the road s

DISCUSSION OF “30-METRE” GEOMETRYA1.1 The European Committee for Standardization (CEN)originally developed the geometry used in this standard formeasuring the retroreflectance of preformed tape (entranceangle 88.76 and observ

37、ation angle 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. A1.1). The geometry is considered a goodapproximation for drivers viewi
