1、Designation: E1274 03 (Reapproved 2017)Standard Test Method forMeasuring Pavement Roughness Using a Profilograph1This standard is issued under the fixed designation E1274; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of

2、 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 test method covers the measurement of pavementroughness using an articulated multi-wheeled profilograph atleast

3、23 ft (7 m) long (Fig. 1 is typical).1.2 This test method utilizes a surface record made bymoving the profilograph longitudinally over the pavement atless than 3 mph (5 km/hr). The record is analyzed to determinethe rate of roughness and to identify bumps that exceed aspecified threshold.1.3 The val

4、ues stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 This standard does not purport to address all of thesafety problems, if any, associated with

5、 its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use. See Section 6 forspecific hazard statement.1.5 This international standard was developed in accor-dance with i

6、nternationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.2.

Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 blanking banda band of uniform height with itslongitudinal center positioned optimally between the highs andlows of the surface record depicting at least 100 ft (30 m) o

8、fpavement (see Fig. 2).3.1.2 cutoff heighta specified distance of a high on thesurface record from a chord representing 25 ft (7.5 m) on thelongitudinal scale. The chord may represent less than 25 ft(7.5 m) if it is from the lows on each side of the high (see Fig.2).3.1.3 rate of roughnesssum of the

9、 roughness divided bythe longitudinal distance covered by the blanking band.3.1.4 roughnessheight of each continuous scallop roundedto the nearest 0.05 in. (1 mm), except those less than 0.03 in.(0.8 mm) vertically and 2 ft (0.6 m) longitudinally.3.1.5 scallopsexcursions of the surface record above

10、andbelow the blanking band (see Fig. 2).4. Significance and Use4.1 This test method provides a means for measuring theroughness of new or rehabilitated pavements. Results maydiffer between profilographs of different designs and thereforewill not necessarily agree with roughness measurements byother

11、profilographs or other roughness-measuring equipment.5. Apparatus5.1 Profilographs:5.1.1 With Uniformly Spaced WheelsA reference platformcomprised of dollies articulated by rigid members or trusses sothat all the wheels are supporting the profilograph. There mustbe at least twelve reference platform

12、 wheels, and the axes ofthese wheels must be uniformly spaced throughout the effec-tive length of the profilograph.3The effective length must be atleast 23 ft (7 m) long. A surface sensing wheel and recordershall be located at the center of the reference platform. Thediameter of the surface sensing

13、wheel shall be at least 6 in.(150 mm). If the recorder is graphic, its scales shall be 1:1vertically and 1:300 longitudinally (1 in. = 25 ft). If therecorder is digital (optional analog display must have the samescales as the graphic recorder), it must sample 5 times/longitudinal inch of travel and

14、record the relative height of thesurface to at least the nearest 0.01 in. (0.25 mm).1This test method is under the jurisdiction of ASTM Committee E17 on Vehicle- Pavement Systems and is the direct responsibility of Subcommittee E17.31 onMethods for Measuring Profile and Roughness.Current edition app

17、n the Decision on Principles for theDevelopment of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.15.1.2 With Non-Uniformly Spaced WheelsIt shall be asdescribed in 5.1.1, except the axes of the reference-platform

18、wheels are not uniformly spaced but are at least 1 ft (0.3 m)apart so no two wheels cross the same bump at the same time.The recorder can be located elsewhere, but surface sensingequipment must be located at the center of the referenceplatform. A common apparatus with non-uniformly spacedwheels is t

19、he California profilograph (see 2.1).5.1.3 There are differences in frequency responses betweenprofilographs with uniformly spaced wheels and profilographswith non-uniformly spaced wheels (see Fig. 3).5.2 Blanking Band Template (optional)Approximately2-in. (50-mm) wide clear plastic strip at least 4

20、 in. (100 mm)long. A common length is 21.12 in. The center of the templateis marked with an opaque strip the width of the stipulatedblanking band throughout its length and with lines every 0.1 in.(2 mm) above and below the blanking band.5.3 Excessive Height Template (optional)Clear plasticpiece mark

21、ed with a 1.00 6 0.02-in. (25.0 6 0.5-mm) line thatis the stipulated cutoff height distance from a straight edge onthe template. Two small holes may be drilled to fix the ends ofthe line (see Fig. 2).6. Hazards6.1 Since profilographs in the testing mode are moved nofaster than 3 mph (5 km/hr), do no

22、t operate near traffic withoutproper traffic control devices and use procedures that assure thesafety of testing personnel and the public.7. Sampling7.1 Take profilograph recordings 3.5 6 0.5 ft (1.0 6 0.2 m)from and parallel to both edges of the pavement and to bothsides of each planned longitudina

23、l joint or in each plannedwheel path.7.2 Any exceptions to these sampling requirements (forexample, 25 ft from each bridge) must be stipulated.8. Calibration8.1 Height Recording:8.1.1 Place gauge blocks of 0.5 in. (10 mm) and 1.5 in.(60 mm) under the surface sensing wheel. The record mustindicate th

24、e actual height of each platform within 60.02 in.(0.5 mm).8.1.2 Verify the standardization of the height recordingbefore any week of use, whenever the profilograph is re-assembled and whenever there is evidence of possible inaccu-racy.8.2 Distance Recording:8.2.1 Mark a distance of 100.00 ft (30.00

25、m) on reasonablyeven pavement. Move the profilograph forward until a particu-lar point is at the first mark and make the recorder mark theevent on the record. Move the profilograph forward again untilthe point is at the second mark and make the recorder to markthis event, too. The record must indica

26、te 100 6 1 ft (30.0 60.3 m) between the two events (4.00 6 0.04 in. on graphicrecord).8.2.2 Verify the standardization of the distance recordingbefore any month of use and whenever there is evidence ofpossible inaccuracy.FIG. 1 Typical ProfilographNOTE 1Fig. 2 is graphic for visual reading.

Procedure9.1 Clear the intended profilograph path of all loose materialand foreign objects.9.2 If possible, move the profilograph about 30 ft (10 m)forward to the starting point. Once there, initialize the recorderand make beginning

28、 notations.9.3 Move the profilograph forward no faster than 3 mph(5 km hr), steering it to stay within that prescribed samplingpath. Pertinent observation about surveyed location or unusualconditions may be made on the record only as they occur.Observe the recorder for any unusual operation.9.4 Upon

29、 completion of a sampling path, make endingnotations and review the recording for reasonableness. Repeatthe procedure for successive sampling paths.10. CalculationNOTE 1Calculations can be done manually with the blanking bandand excessive height templates or electronically with routines in acomputer

30、.10.1 Apply the blanking band to successive lengths of thesurface record. Determine the roughness from each scallop.Add all roughness for each stipulated segment. From thesurface record, determine the longitudinal distance between thefarthest points of the beginning and ending scallops or absencethe

31、reof. Divide the result of the addition by the correspondinglongitudinal distance to calculate the rate of roughness for thatsegment of that path.10.2 Apply the excessive height chord to the top of eachwave on the surface record. Identify all bumps that areexcessively high by their locations.11. Rep
