1、Designation:E127403(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 last

2、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 23 ft(7 m)l

3、ong(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 values stated in inc

4、h-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.1.4This standard does not purport to address all of thesafety problems,if any,associated with its use.It is theres

10、nificance 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 profilographs or other roughness-measuring equi

12、rmly 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 wheel shall be at least 6 in.(150 mm).If the recorder
