1、Designation: E1703/E1703M 10 (Reapproved 2015)Standard Test Method forMeasuring Rut-Depth of Pavement Surfaces Using aStraightedge1This standard is issued under the fixed designation E1703/E1703M; the number immediately following the designation indicates the yearof original adoption or, in the case

2、 of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method describes the procedure for the mea-surement of the depth of the rut at a c

3、hosen location in apavement surface using a straightedge and a gauge.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. Within the text, theinch-pound units are shown in parentheses. The values statedin each system are not exact equivalents; theref

4、ore, eachsystem must be used independently of the other. Combiningvalues from the two systems may result in nonconformancewith the specification.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this stand

Significance and Use4.1 Rutted pavement surfaces may have an adverse influ-ence on vehicle handling cha

8、racteristics and may impedesurface drainage, which may reduce friction properties andcontribute to hydroplaning. Rutting indicates deformation orwear of materials in the pavement and may be indicative ofproblems such as asphalt flow, consolidation, shear, or loss ofpavement materials.4.2 The rut-dep

9、th value obtained using this test method maynot correlate well with values obtained using other methods.5. Apparatus5.1 Straightedge:5.1.1 WidthThe bottom rectangular surface of the straight-edge shall be at least 19 mm (0.75 in.) but not more than 75mm (3.0 in.) wide in the measurement plane.5.1.2

10、LengthThe preferred lengths of the straightedge areeither 1.83 metres (6 ft), 2 metres (6.56 ft), 3 metres (9.84 ft),3.05 metres (10 ft), 3.66 metres (12 ft) or 4.88 metres (16 ft).The length shall ensure that the straightedge spans the twohighest points on either side of the rut. The minimum length

11、shall be at least 1.73 metres (5.67 ft).5.1.3 TruenessThe maximum out-of-trueness of the bot-tom surface of the straightedge in the measurement plane shallbe less than6 0.40 mm/m (60.005 in./ft) of length and lessthan 62.5 mm/m (60.03 in./ft) of width. The straightedgemust be rigid enough so that it

12、 always meets this trueness.5.2 Gauge:5.2.1 The rut-depth measuring gauge shall be graduated to 1mm (116 in.) or finer. The bottom surface of the gauge shall beat least 19 mm (0.75 in.) but not more than 75 mm (3.0 in.)wide and span areas of aggregate loss and texture. The gaugeshall have sufficient

13、 range to accommodate the measurement.NOTE 1The straightedge is not mounted on wheels like a rollinginclinometer, refer to Test Method E2133.6.

16、nited States16.1.1 Place the straightedge across the rut. Allow thestraightedge to rest upon the pavement at two contact areas,such that sliding the straightedge along its length in bothdirections will not change the contact areas on the pavement.Avoid locating the contact area at discontinuities th

17、at are widerthan the straightedge bottom.6.1.2 Place the straightedge in a plane perpendicular to thedirection of traffic movement. The bottom surface of thestraightedge shall be parallel to the longitudinal slope of thepavement. Do not place the straightedge on any discontinuitieson the pavement su

18、rface, for example, potholes or loose debris.6.1.3 The longitudinal interval between successive straight-edge placement should be related to the precision required forthe use of the data.6.2 Gauge Placement:6.2.1 Place the gauge between the two contact areas per-pendicular to the reference plane cre

19、ated by the bottom of thestraightedge and perpendicular to the longitudinal slope of thepavement. The bottom of the gauge shall be in contact with thepavement at the time of the measurement. Do not place thegauge on any discontinuities on the pavement surface, forexample, potholes or loose debris (s

20、ee Fig. 1).6.3 Rut-Depth Measurement:6.3.1 Measure the distance between the bottom surface ofthe straightedge and the pavement after the gauge has beenplaced as described in 6.1 and 6.2.6.3.2 Measurements should be made to the nearest gradua-tion of the gauge. A sufficient number of measurements sho

21、uldbe made along the straightedge to determine the greatestdistance between the straightedge and the pavement. Thegreatest distance can be measured between the two contactareas or along the full straightedge length.7. Report7.1 Report at least the following information:7.1.1 Date,7.1.2 Test location

22、 to uniquely identify the data reported(such as: Road number, Station, Offset, Wheelpath, or Lane),7.1.3 Dimensions of the bottom surface of the straightedge,7.1.4 Dimensions of the bottom surface of the gauge, and7.1.5 Greatest rut-depth measurement (see 3.2.2)tothenearest graduation of the gauge s

23、pecified in 5.2.1.8. Precision and Bias8.1 At this time no precision estimate from a statisticallydesigned series of tests at different locations has been obtained.8.2 Since there is no accepted reference material suitable fordetermining the bias for the procedure for measuring therut-depth of pavem

24、ent surfaces using a straightedge, no state-ment on bias is being made.NOTE 2The precision of each rut-depth measurement depends on thedesign of the depth gauge, surface texture, and operator skill. Theprecision for the selected equipment should be determined by the userthrough a statistically-desig
