ÖGELE RoadScan, a contactless tem-
perature measurement system, makes
paving quality measurable and verifiable.
Making quality measurable is one of the big
issues for contractors and clients worldwide.
One of the key criteria for the durability of
roads is maintaining a constant temperature
of the freshly paved asphalt. As a result, the
significance of area-wide temperature mon-
itoring is currently on the rise in more and
more markets. With RoadScan, VÖGELE’s
contactless temperature measurement sys-
tem, the company is on the leading edge of
this future trend.
High-precision infrared camera with
100% measurement coverage
The heart of the RoadScan system is an
infrared camera which scans the asphalt
pavement behind the screed over the entire
area. What sets the system apart is its
unrivalled measuring accuracy. The VÖGELE
system captures grids of 25 x 25 cm-sized
tiles at a measuring width of 10 m.
Each of these tiles contains up to 16 sin-
gle measuring points which are then used
to calculate a mean value. That allows the
system to capture the newly paved sur-
face with no gaps, and so no theoretical
or computed values need to be added. The
measurable temperature range of Road-
Scan lies between 0 °C and 250 °C with a
tolerance of only ±2 °C.
The purpose of RoadScan’s other compo-
nents is to capture the base temperature
before paving (pyrometer), record precise
positional data (high-precision GPS receiv-
er) and document the wind strength and di-
rection, ambient temperature, air pressure
and humidity (weather station available as
an option).
Integration into ErgoPlus 3
As one would expect of VÖGELE equipment,
the RoadScan system is intuitive to operate
and can easily be activated from the paver
operator’s ErgoPlus 3 console. The user
views the temperatures currently being
recorded on the colour display, and these
are clearly visualised using thermal images
and in real time. The paver operator can
programme the colour scale to allow any
deviation from the required temperature
of the freshly paved asphalt to be quickly
identified. That makes VÖGELE RoadScan
an effective instrument for ensuring high
paving quality – without unduly increasing
the paving team’s work load.
Encrypted recording of measurement
data
The measurement data obtained using
RoadScan is also stored in the paver
operator’s ErgoPlus 3 console. After paving,
this data can be read off via an external
data storage device. At the same time,
VÖGELE has taken effective measures to
protect the data via a specially designed
memory stick which communicates with a
VÖGELE interface on the paver operator’s
ErgoPlus 3 console; this in turn transfers
the data in encrypted form. The data is then
analysed in the office using the RoadScan
Analysis web application, which presents
the data in different types of diagrams and
in a map view.
Integration into WITOS Paving
VÖGELE RoadScan can also be integrated
into WITOS Paving. This innovative IT-
based tool for the process optimisation of
asphalt job sites helps companies to plan
more transparently and respond flexibly
to interruptions in ongoing operations,
significantly increasing overall cost
efficiency.

The values obtained are stored in the paver
operator’s ErgoPlus 3 console and can be read off
securely. After the data has been uploaded, it is
analysed in the office using the RoadScan Analysis
web application.

measurement system, makes paving quality
measurable and verifiable.
The heart of RoadScan is an infrared camera which
scans the asphalt pavement behind the screed over
the entire area. What sets the system apart is its
unrivalled measuring accuracy.
The surface temperature can be tracked on the
display of the paver operator’s ErgoPlus 3 console.
This allows the paving team to respond directly
to variations in temperature and ensure perfect
paving quality.
