Measurement of Megatexture and Macrotexture by the VTI Mobile Laser
Profilometer in Denmark 1993
by Per Anund and Ulf Sandberg
Swedish Road and Transport Research Institute
S-581 95 Linköping, Sweden
SUMMARY
This report presents the results of the texture measurements made by VTI, with
invaluable help from Mr Hans Thorsen from Vejdatalaboratoriet in Denmark in
October 1993 on behalf of Mr Hans Bendtsen, Vejdatalaboratoriet*. The
measurements have been carried out on a 'low noise road surface' and a
'reference surface' in østerbrogade in Copenhagen and on ñve test surfaces on
highway No. 120 at Viskinge on Zealand. The measurements were carried out
in both diraztions in sections of 80 or 160 meters length, depending on the
length of the actual test section.
The texture measures collected by the VTI Mobile Laser Proñlometer include
Estimated Texture Depth (ETD), Root Mean Square (RMS), Texture Depth
predicted by the MAcrotexure Level (TDMa), Macrotexture Level (LMa),
Megatexture Level (LMe) and texture spectra expressed in 25 third-octave bands
covering the texture wavelength range of 2-500 mm. ETD is a measure that
attempts to predict from the profile curve a mean texture depth measured
according to the volumetric method (also called "sand-patch method").
* After a re-organization 1993-12-31, the Trafñc Research Department of the
Road Data Laboratory became part of the Department for Safety and
Environment of the Danish Road Directorate.

BACKGROUND
In a joint Nordic project on "Low-Noise Road Surfaces" the Danish Road Data
Laboratory under the Danish Road Directorate* has a number of test road
surfaces, with higher air voids content than normal, which are intended to give
various noise reductions in comparison to a couple of reference surfaces of
conventional type. Two of these experimental surfaces are located on a street in
Copenhagen and ñve are located on a highway near Viskinge on Zealand
[Sandberg et al, 1993].
In the first years of service, it was noted that a few rather unexpected noise
reduction values were measured. It has been speculated whether these 'peculiar'
results could be explained by texture changes but since no texture measurements
were made, it was not possible to verify or reject this. During 1993 it was
decided to test not only noise but also road surface texture. VTI was
commissioned to conduct such tests utilizing the VTI Mobile Laser
Proñlometer.

Road Data Laboratory became part of the Department for Safety and
Environment of the Danish Road Directorate.
2.1
The VTI Mobile Laser Profilometer
2.1.1
General Description
The VTI Mobile Laser Profilometer consists of an electro-optical system, mounted
in a car, which measures the vertical distance between the vehicle body and a small
laser spot on the road surface, a real-time third-octave band spectrum analyzer, a
computer for data processing and presentation of results, as well as a Volvo 245
car in which the equipment is mounted. The computer is equipped with a data
acquisition board and a GPIB interface.
2.1.2
Principle of Operation
The non-contact measurement makes use of an infrared laser beam which creates a
light spot on the road surface. An optical lens system, looking at the light spot at
30° inclination rel. to vertical laser beam, projects this light spot onto a certain
position on a linear silicon sensor. This gives an output current with a certain
relation to the position of the light spot on the sensor and thus to the vertical
position of the light spot on the road. When the vehicle moves at constant speed,
this light spot moves over the surface profile, thus giving a profile curve which
describes the texture of the surface.
After regulation of the signal in order to have an Optimum light spot intensity and
linearization of the output signal, the output is fed to a frequency analyzer which
calculates on-line the texture spectrum of the profile signal. At the same time, the
output signal is fed to a computer which stores the complete profile curve in a file.
Based on the texture spectrum and the profile curve, some overall texture
descriptors, which have been found to have interesting relationships with road
surface Characteristics and vehicle performance, are calculated.
The profile curve is used for calculation of the two descriptors ETD and RMS,
where ETD is derived from the average area under a line which touches the peaks
of the surface. This area has a very close relationship with the volume of the sand
which fills the surface voids when the so-called sand-patch method is used to
measure the texture depth. RMS is the Root Mean Square of the profile curve.
For a measurement over 80 m, the profile curve is divided into 512 parts and for
160 m it is divided into 1024 parts, where each part is 156.25 mm long. For
historical and technical reasons, only 140 mm of 156.25 mm (90 %) of each
profile is used for ETD and RMS calculations. A total ETD and RMS are
calculated as the mean value of all these 512 (or 1024) individual values.
In the typical printout of a profile curve, seen in Fig. 1, the level distribution is
plotted to the right of the profile curve. The thick distribution curve corresponds to
the average of all measurements of this run and the thin curve to the particular
profile shown in the figure. The text within the frame concerns the following: The
left column shows the data for the particular profile shown in the figure, the right
column shows the data for an average profile based on all profiles recorded in the
run. An example of a texture printout with spectrum is shown in Fig. 2.
Results may be printed immediately after completion of measurements or at a later
time for both the proñle curve and the texture spectrum. For a more thorough
information about the equipment, see [Sandberg & Anund, 1992].
Note: The ETD values have been calculated based on a transformation equation
determined in an experiment many years ago. The equation is assumed to result in
ETD values which are nominally equal to "sand-patch" texture depth. In a recent
and very extensive measurement series, it has appeared that a slight modiñcation of
this equation is necessary. While international standardization work is still in
progress, this equation has recently been proposed. See [ISO/CD 13473] for a
pr0posed international standard. The conversion factor from "old" (= the values in
this report) to "new" ISO ETD values here is: ETDiSO = 0.41 + 0.68 - ETDold.

Cahbration
Calibration of the equipment was made before and after measurement on each test
site. The entire measun'ng system was calibrated by means of a disc, having a
periodical triangular profile with an amplitude of 10 mm peak-to-bottom and a
texture wavelength of 20 mm, which was rotated undemeath the laser with a speed
equal to that during measurement. When calibrating the profile curve, the curve
was ampliñed to match an RMS value of 2.887 mm which is the theoretically
calculated RMS value of such a profile curve. In order to calibrate the texture
spectrum, the spectrum analyzer was fed with the triangular proñle signal and the
attenuation of the analyzer was set (manually) so that a level of 69.1 dB was read
in the 20 mm wavelength band, i.e. for the fundamental frequency component.
This level is the theoretical level of the fundamental frequency of such a profile,
determined by fourier transformation of the proflle signal. There are printouts of
profile curves in Appendix 3 and printouts of texture spectra in Appendix 2 from
the triangular calibration proñle.

TEST SITES
Two test sites on østerbrogade in Copenhagen, here named 'Reference' (R) and
'Porous' (P), as well as five test sites at Viskinge, were measured. These sites are
the same as presented in [Sandberg et al, 1993]. In Viskinge the test sites are
named A, B, C, D and E; site A is the most eastward and E the most westward
sites of them. The 'Location' identification in Table 1 corresponds to [Sandberg et
al, 1993]. Weather conditions were very good during all the measurements in
Copenhagen and Viskinge. It was approximately 10°C in the air and road surfaces
were dry. The 'Test site length' in Table l shows the length of every single
measurement on that site and the 'No. of Runs' shows how many measurements
that were made. All measurements were made in the left wheel track in both
directions. Table l describes all the test sites in this experiment, regarding
location, type of surface etc.

Table 2 presents the overall values obtained on the sites in Denmark with all runs
on the same test site averaged. 'No. of proñle sections' refer to the number of 140
mm long proñle sections on which the RMS and ETD values are based. The
equipment records any drop-out of the signal, i.e. when the signal is considered as
invalid, the values under 'invalid' present the drop-out proportion. A drop-out
proportion exceeding 10% on a rough texture and 5 % on a smooth texture is
usually not considered to be acceptable. For new porous surfaces it is not unusual
with a drop-out proportion somewhat exceeding 10%. The 'max. mag.' is the
wavelength of the third-octave-band in the texture spectrum with the maximum
magnitude. This value gives an indication of the 'average' spacing between
individual stones (the bigger ones). This has been found to, generally, be one
third-octave band bigger than the maximum chipping size of the test surfaces. The
average spectrum for each test site is presented in Appendix 1. The texture spectra
for each test site and each run are presented in Appendix 2. Since there were no
differences in texture between the two directions of the road, both directions are
represented in the averaged result.
Table 2 Overall texture values obtained on the test sites in Denmark. Note that,
generally, the max. chipping size is predicted by 'Max.mag' as one
third-octave lower than 'Max.mag'. Please read Note on p. 3 re. ETD.

Of the measures above, as a measure representing macrotexture in general, the
reader is adviced to emphasize the ETD, since this measure is subject to
standardization in on-going ISO work. It has also been found to be a very good
measure for describing the texture influence on friction (speed dependance), see
[PIARC, 1994]. However, as measures representing noise Characteristics, LS and
L80 are the most interesting (Sandberg, 1987]. L5 has in inverse relation with
high-frequency noise and L80 a proportional relation with low-frequency noise.
The megatexture level, LMe is a measure whichgives an idea of the influence on
noise at very low frequencies (below approx. 200 Hz).

COMMENTS TO THE RESULTS
Maximum chipping size:
The measurements verify the maximum chipping size to be 12 mm for the
østerbrogade reference surface, for the Viskinge D (Drainage asphalt) and for the
Viskinge E (open-graded) surfaces. However, for the Viskinge A surface, it
appears that the 'Max.mag' occurs at 12.5 mm instead of the expected 16 mm.
This indicates that this surface has a dominance of le mm chippings which
perhaps makes it somewhat less 'noisy' than what is normal for an AB12t surface.
The porous 8 mm surfaces at Viskinge (B and C) should have a 'Max-mag.' at 10
mm, but the measured value at 12.5 mm indicates that either there is a fraction of
10 mm chippings, or the spacing between the chippings is bigger than necessary.
Whatever the reason is, this should make the surface somewhat noisier than if it
had hit the target perfectly. The same applies for the porous surface on
østerbrogade, but to a higher extent, since 'Max.mag.' there is 16 mm instead of
expected 10 mm. Since we have no previous experience of measurements of
texture on porous 8 mm surfaces, it is, however, impossible to say if the effects
noted are a result of wear or other changes, or if they were 'built-in' from the
beginning.
Relation between LS and LSO:
For a surface to be 'quiet', the relation between L80 and LS shall be as low as
possible. This indicates (again) that the Viskinge A surface should be a relatively
quiet surface, somewhat better than the østerbrogade reference. The Viskinge E
surface should be relatively 'noisy'. All of the porous surfaces have a higher value
for L80/L5 than Viskinge A, but their most important noise-reducing
Characteristics is the porosity which occurs inside the pavement and cannot be
measured by the proñlometer. However, a comparison within the porous surface
group reveals that Viskinge B and C should be more 'quiet' than Viskinge D. They
should also be more quiet than the porous surface on østerbrogade even though the
latter should be nominally similar. The østerbrogade surface has a lower value for
L5 which, together with the lower ETD value, indicates that the surface may be
more clogged.
Note that the L5 and L80 measures do not take proñle skewness into account, see
below.
ETD:
The østerbrogade reference surface has a texture which is relatively low. This and
Viskinge A have values which are rather similar to what is normally measured on
the same type of surfaces in Sweden. The much lower ETD for Viskinge E than for
Viskinge D indicates that the former surface cannot have any significant porosity
left. Viskinge B and C are very similar, with no expected noise difference.
These measures do not offer any interesting information as compared to the ones
already commented. They are included here to facilitate any comparisons with
other measurements.
Random run-to-run variations:
In østerbrogade and in Viskinge 2-4 individual runs on each test site were made.
The random variation between these runs, expressed as the maximum difference of
two individual runs on the same test site, was in most cases less than 0.05 mm for
ETD and RMS measures. However, on Viskinge A, variations between individual
runs for the ETD measure were up to 0.2 mm and the two Viskinge D runs
resulted on an ETD difference of 0.36 mm. The maximum difference between runs
in spmtral measures, such as LMa, LMe, L5 and L80, were less than 1.2 dB. The
variations are generally caused by inhomogeneities in texture, mainly in the lateral
direction, and a corresponding variation in lateral position of the car.
Profile distribution:
The distribution of profile on a vertical scale is shown in the rightmost parts of the
figures in Appendix 3. One can distinguish between two types of distribution. For
the dense surfaces, the distribution is mainly "normal" and symmetrical around an
"average" level. The other type appears for the porous surfaces, resulting in a skew
distribution, being unsymmetrical around some "average" level. Such proñles have
their texture directed more "downwards" than "upwards".
The latter is good for low noise production, since it reduces vibration excitation to
the tyre tread while still providing a lot of drainage area undemeath the tyre/road
contact patch.
There is a tendency that particularly the østerbrogade P surface is good in this
respect, since it has a more pronounced skewness than the others, in particular a
minimum of profile above the level which is dominating the distribution. This may
compensate for the maximum chipping size which was found to be a little higher
than desirable (see above under "Maximum chipping size" and "Relation between
L5 and L80").
