BOMAG EVIB 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, documen-tation of compaction processes and the compaction quality achieved are becoming more and more important.

BOMAG EVIB measuring technology: Reaching targets. Every time.

BOMAG compaction measurement and docu-

mentation systems are used for continuous and

surface covering compaction control. BOMAG

measuring technology is based on the EVIB value.

This is a value that calculates the soil stiffness in

MN/m2 during the compaction process. The EVIB

value is a physical measured value that corre-

lates 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 rol-

ler drum. By changing the EVIB value, the roller

operator is permanently informed of compaction

progress.

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 EVIB 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 EVIB value

arises from the analysis of the load curve, as this

correlates with the stiffness of the soil.

Unmatched precisionOnly BOMAG uses two measuring sensors on the

drum to optimise measuring accuracy. The measur-

ing density is also unparalleled: The EVIB value is

continuously measured with a measuring density

value of up to 10 cm. This ensures that every weak

spot is detected.

Different indicator systemsThere are various instruments to choose from

when it comes to indicating the EVIB value. The

BOMAG EVIB 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 EVIB analogue

display, located with the driving instrumentation.

The advantages:n Determination of the EVIB valuen Indication of trend towards a compaction

increasen Detection of weak spots and inconsistencies.

And modules are available to upgrade to other

measuring system versions.

The BOMAG Terrameter BTM is even more con-

venient to use. Instead of an EVIB analogue display,

it has a BOMAG Operation Panel (BOP), a conveni-

ent 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 dia-

grams and bar charts to document coverage of

small and medium-sized sites.

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 EVIB 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 EVIB values are dis-

played 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 touchscreenn USB memory stickn Robust, lockable tablet PC holdern BCM 05 software

*German regulations ZTVE-StB 2009, ZTV SoB-StB 04, TPBF-StB Part E2, DB Ril 836 Austrian regulations: RVS 8S.02.6

The complete solution: BCM 05 and BCM 05 positioning.

The optional BOMAG Compaction Management BCM 05 offers the most convenient solution for docu-menting 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.

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 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:

BCM 05 positioning – linking of EVIB measured values with position data.

BCM 05 positioning links the EVIB 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 satellite-assisted reference service.

For immediate use anywhere: BOMAG StarFire GPS receiver.

softwaren BCM 05 positioning softwaren GPS system with holder and wiring loom

BOMAG software is capable of interfacing with

conventional DGPS systems with and without a

reference station. However, the positioning accu-

racy depends on the chosen GPS system. The raw

data supplied by the GPS system can be trans-

formed 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.

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

In conjunction with GPS applications, the technol-

ogy helps the contractor to monitor and control

asphalt compaction work. During compaction, the

calculated EVIB values which are used as a refer-

ence value for compaction progress are continu-

BOMAG measuring technology – also used in asphalt compaction.

The EVIB measuring technology is also used for asphalt compaction. The basis is the self-regulating ASPHALT MANAGER rollers with integrated EVIB 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.

BCM net – the transparent construction site up close: Seamless transparency for higher cost-effectiveness.

Networking several rollers on site provides an

opportunity to create an overall picture of com-

paction 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 receiv-

ers and connected up via a wireless network. They

permanently transmit their positions, the compac-

tion results and other necessary parameters, such

as the asphalt temperature or speed to the server.

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.

spots in the subsoil to

tation systems provide the basis of cost-effective
