DIN EN 13036-8:2008-06 EN 13036-8:2008 (E) 4 Introduction Road profile transverse unevenness affects safety and ride comfort. Transverse uneveness demands can differ from one road to another and are highly related to the spe

21、ed limit, the kind of traffic, the climatic conditions, the accepted comfort limits, etc. Road profile transverse unevenness is consequently key information for acceptance of newly laid pavements and for road maintenance management systems. Road profile transverse unevenness encompasses a variety of

22、 aspects, such as: the crossfall of the transverse profile, irregularities or different defects in the transverse profile (steps, ridges/dips and edge slumps) and the longitudinal ruts in the wheel paths caused by the traffic. The measurement of road transverse unevenness has been a subject of much

23、research for more than 70 years, resulting in many different measuring methods. Measurement devices can be split into: - stationary equipment, such as e.g. the straightedge for irregularities and longitudinal ruts or rod and level for crossfall in single profiles, - dynamic equipment, such as e.g. t

24、he profilometer, which is dependant on the characteristics of the device, suitable for measuring all mentioned aspects for single profiles as well as section (mean) values. This European Standard has been written to be used in conjunction with the European Standards EN 13036-6 (Profilometer) and EN

25、13036-7 (Straightedge). DIN EN 13036-8:2008-06 EN 13036-8:2008 (E) 5 1 Scope This European Standard defines the different transverse unevenness indices of the pavement surface of roads and airfields and the appropriate methods of evaluation and reporting. The indices have been defined principally in

26、dependent of the measurement device. This European Standard focuses on transverse unevenness measurements for the following three purposes: - indices to provide a means for quality control of pavement surfaces of newly laid pavements, especially with respect to crossfall and the evidence of irregula

27、rities due to improper laying and/or compacting action. - indices to be used for evaluating the condition of pavements in service as part of routine condition monitoring programs. They are intended to detect transverse deformations caused by the traffic, pavement wear or subsurface movement. - indic

28、es to be used for resurfacing activities on pavements in use. The parameters and evaluation methods are applicable both for roads and airfields. 2 Normative references The following referenced documents are indispensable for the application of this document.

31、 between two consecutive transverse profile measurements 3.2 bias difference between the expectation of the test results and an accepted reference value NOTE Bias is the total systematic error as contrasted to random error. There may be one or more systematic error components to the bias. A large sy

32、stematic difference from the accepted reference value is reflected by a large bias value (see ISO 3534-1). 3.3 crossfall transverse gradient across a section or full width of a pavement measured perpendicular to the centre line DIN EN 13036-8:2008-06 EN 13036-8:2008 (E) 6 NOTE Crossfall can be expre

33、ssed as a percentage, a ratio (e.g. 1 to 30) or as an angle to the horizontal. By convention, it is positive when the right end of the profile is lower than its left end for right hand traffic and the opposite for left hand traffic. 3.4 edge slump deviation of the pavement edge below a straight refe

34、rence line 3.5 irregularity any deviation of a surface from the straight reference line 3.6 layer structural element of a pavement laid in a single operation 3.7 pavement structure composed of one or more layers of selected material designed to carry traffic 3.8 pavement surface or surface course up

35、per layer of the pavement that is in contact with the traffic 3.9 precision closeness of agreement between independent test results obtained under stipulated conditions NOTE Precision depends only on the distribution of random errors. The measure of precision is usually computed as a standard deviat

36、ion of the test results. Less precision is reflected by a larger standard deviation (see ISO 3534-1). 3.10 repeatability maximum difference expected between two measurements made by the same machine, with the same tyre, operated by the same crew on the same section of road in a short space of time,

37、with a probability of 95 %. 3.11 ridge any deviation above a straight reference line 3.12 dip any deviation below a straight reference line 3.13 rut/pothole any deviation below the straight reference line, normally in the wheel path 3.14 rut depth greatest deviation of the transverse profile of a pa

38、vement surface and a virtual straight reference line of length L sliding on the surface of the profile within the limits of the analysed width, by leaving one edge of the rut towards the other edge. NOTE 1 The length of the virtual reference should be mentioned within the results. NOTE 2 Rut depth i

The theoretical water depth in a depression or dip is often called “pond depth”. 3.18 transverse profile intersection between the road surface and a reference plane perpendicular t

42、o the road surface and to the lane direction 3.19 trueness closeness of agreement between the average value obtained from large series of test results and an accepted reference value NOTE The measure of trueness is usually expressed in terms of bias (8.3) and reflects the total systematic error as c

43、ontrasted to random error. There may be one or more systematic error components to the trueness. A large systematic difference from the accepted reference value is reflected by a large value (see ISO 3534-1). 3.20 wheel paths area of a pavement surface where the large majority of vehicle wheel passa

Crossfall mean X is defined as the angle between the horizontal and the regression straight line through the transverse road profile fixed by at least seven measurement points across that profile.
