BOMAG compaction measurement and documentation systems
BOMAG E VIB measuring technology:
Reaching targets. Every time.
BOMAG E VIB measuring technology makes it possible to control compaction even during the compaction
process. Surface covering and precise.
Quality requirements on earthworks and road construction are continually increasing. The aim is to
meet quality standards and to optimise the use of compaction machinery. With this in mind, documentation
of compaction processes and the compaction quality achieved are becoming more and more
important.
BOMAG compaction measurement and documentation
systems are used for continuous and
surface covering compaction control. BOMAG
measuring technology is based on the E VIB value.
This is a value that calculates the soil stiffness in

MN/m 2 during the compaction process. The E VIB
value is a physical measured value that correlates
directly with the plate-loading test used in
earthworks and road construction.

It expresses the correlation between the ground
contact force and the indentation of the roller
drum. By changing the E VIB value, the roller
operator is permanently informed of compaction
progress.

control.
The result:
The efficiency of compaction work is improved,
as unnecessary passes can be prevented, weak
spots discovered in good time, and time and effort
carrying out inspections can also be reduced. The
contractor will save time and money.

How exactly is the E VIB value created?
BOMAG compaction measuring systems use the
interaction of the acceleration of the vibrating drum
and the dynamic stiffness of the soil. In general, the
soil stiffness will increase as compaction increases.
If the soil becomes stiffer, the drum acceleration will
also increase.
The measuring sensors record this acceleration
and from this determine the effective contact force
between the soil and drum and, at the same time,
the oscillating path of the entire drum. If the contact
force is then laid on top of the oscillating path of the
drum, this results in a loading and unloading curve
for every revolution of the eccentric weight in the
drum. The surface included in this curve correlates
with the compaction energy imparted. The E VIB value
arises from the analysis of the load curve, as this
correlates with the stiffness of the soil.
Recording vertical and horizontal acceleration.
Unmatched precision
Only BOMAG uses two measuring sensors on the
drum to optimise measuring accuracy. The measuring
density is also unparalleled: The E VIB value is
continuously measured with a measuring density
value of up to 10 cm. This ensures that every weak
spot is detected.

BOMAG compaction measurement and documentation systems
Different indicator systems
There are various instruments to choose from
when it comes to indicating the E VIB value. The
BOMAG E VIB meter BEM represents the starter
device. In addition to the two acceleration sensors,
the unit includes a distance gauge, an electronic
unit and a circular instrument, the E VIB analogue
display, located with the driving instrumentation.
The advantages:
n Determination of the E VIB value
n Indication of trend towards a compaction
increase
n Detection of weak spots and inconsistencies.
And modules are available to upgrade to other
measuring system versions.

The BOMAG Terrameter BTM is even more convenient
to use. Instead of an E VIB analogue display,
it has a BOMAG Operation Panel (BOP), a convenient
control unit.
Other advantages:
n The driver sees a message on the display when
the target value has been reached or if further
compaction is no longer possible.
n The results are displayed digitally and in the
form of bar charts.
n The printer can be used to print out line diagrams
and bar charts to document coverage of
small and medium-sized sites.

Technology
The complete solution:
BCM 05 and BCM 05 positioning.
The optional BOMAG Compaction Management BCM 05 offers the most convenient solution for documenting
results. Informative and detailed measuring records can be created easily for specific sites;
this ensures comprehensive documentation complying with the rules and regulations* of Surface
Covering dynamic Compaction Control (SCCC).
The BCM 05 tablet PC: suitable for
construction sites, user friendly and
delivers information.
Using BOMAG measuring technology,
the operator really has everything
under control while work is in
progress.
The BOMAG COMPACTION MANAGEMENT BCM 05
is used for large scale projects and at all sites
where surface covering dynamic compaction
control is required or recommended. BCM 05 is
a tablet PC suited to use on construction sites;
it determines, displays and saves the E VIB values
of the entire construction site using the BCM 05
mobile software. This means no more hassle with
printing. Compaction can be tracked in real-time,
lane by lane, and location by location on the large
display. The PC displays the entire surface to be
compacted. The measured E VIB values are displayed
as line diagrams and colour intervals. The
colour intervals can be chosen as required, so that
both compaction progress and weak spots can be
clearly identified during work. With a USB-stick
the data can be transferred to a stationary PC for
analysis and documentation with the software
product BCM 05 office.
The BCM 05 scope of delivery includes:
n Tablet PC with touchscreen
n USB memory stick
n Robust, lockable tablet PC holder
n BCM 05 software
In contrast to the terrameter, which prints out individual documents
on site, the BCM 05 offers the convenience of an analysis of the entire
construction site from one stationary PC.

BCM 05 positioning – linking of E VIB measured values
with position data.
BCM 05 positioning links the E VIB measured values with the position data of a differential GPS system.
Documentation becomes even more user friendly: No fields need to be defined in advance and the
roller driver does not need to assign his current position to the defined track. After all, the roller
knows itself exactly where it is.
Precise position determination to the centimetre with a reference
station.
Precise position determination to within 20 cm using a satelliteassisted
reference service.
n BCM 05 display with BCM 05 mobile and office
software
n BCM 05 positioning software
n GPS system with holder and wiring loom
For immediate use anywhere: BOMAG StarFire GPS receiver.
BCM 05 positioning ensures that documentation
is safe from operating errors and manipulation.
Compaction is completely documented, just like on
a map.
The following systems are required in order to
use satellite-assisted surface covering dynamic
compaction control:
BOMAG software is capable of interfacing with
conventional DGPS systems with and without a
reference station. However, the positioning accuracy
depends on the chosen GPS system. The raw
data supplied by the GPS system can be transformed
with the aid of BCM 05 into construction
site coordinates.
For additional orientation, points and/or axes can
be easily read into the portrayed structure of the
construction site.

Use of the Starfire iTC system for surface covering compaction
control ...
... and use of GPS receivers with separate antennae and reference
stations.
BOMAG uses the compact and simple to install
Starfire iTC system as the DGPS solution; this
works with a satellite-assisted reference service
to achieve positional accuracy to at least 20 cm.
This system does not require a reference station,
as BCM 05 positioning can also be combined with
any other conventional DGPS systems; an existing
infrastructure on site can be used without difficulty.
The Starfire iTC system is extremely compact and
can be installed quickly and easily. There is no
need for specialist staff to commission the system.

BOMAG measuring technology – also used in asphalt
compaction.
The E VIB measuring technology is also used for asphalt compaction. The basis is the self-regulating
ASPHALT MANAGER rollers with integrated E VIB measuring technology and temperature sensors. When
the rolling temperature is greater than 100 °C, the stiffness value determined by the roller can usually
be used directly as a reference for compaction quality.
In conjunction with GPS applications, the technology
helps the contractor to monitor and control
asphalt compaction work. During compaction, the
calculated E VIB values which are used as a reference
value for compaction progress are continu-
ously documented together with the number of
passes, the asphalt temperature, amplitude and
frequency, and all the associated construction site
coordinates.

BOMAG compaction measurement and documentation systems
BCM net – the transparent construction site up
close: Seamless transparency for higher costeffectiveness.
Networking several rollers on site provides an
opportunity to create an overall picture of compaction
over the entire site. With BCM net, not
only the data from one machine, but data from all
machines involved in the compaction work can be
recorded and displayed on one screen.
For this, the rollers are equipped with GPS receivers
and connected up via a wireless network. They
permanently transmit their positions, the compaction
results and other necessary parameters, such
as the asphalt temperature or speed to the server.
n Support in terms of comprehensive measured
data management – giving clear, cost-effective
organisation of the construction site
n Easy and quick to install DGPS solutions that
work independently of reference stations
n Recording and documentation of data from all
machines involved in the compaction process
via BCM net – for more efficiency on construction
site
BOMAG compaction measurement and documentation
systems provide the basis of cost-effective
compaction. They provide high, uniform compaction
quality, save the contractor time, effort and
money, and increase protection against subsequent
claims for remedials.
The data is updated every 5 seconds and the
server distributes the new „picture“ to all network
users. This enables every roller operator to follow
their own compaction progress and that of the
other machines.
Overview of the advantages:
n Early detection of weak
spots in the subsoil to
minimisation risks
n Reduction in unnecessary
passes once specified
values have been
reached.
n Reduction in time and
effort on inspections
n Smooth documentation
of compaction quality
on asphalt construction
and earthworks
BCM net – the online network
enables direct data exchange
between the rollers.
