here was a time when building a road
involved laying material, compacting it
and hoping that at the end of the day it
met the client’s specifications.
The problem with that approach is the
uncertainty for the contractor throughout
the project. It’s better to know as you go
along whether the road is going to meet a
developer’s requirements, and better still to
be able to document and prove the quality
of the work.
Technology plays a central role in the
development of modern roadbuilding
equipment, and a string of new machine
control and telematics systems have been
introduced to the market in recent years. The
Technology is becoming more and more important to the roadbuilding
sector, helping boost efficiency as well as reduce costs.

looks at the latest developments
aim is to increase the accuracy of roadbuilding
operations and boost efficiency.
For instance, the Saxony-Anhalt state road
construction authority (LSBB) became the first
state construction authority in Germany to
test a new asphalt temperature measurement
system from Moba during a recent partial
resurfacing of the A14 near Magdeburg.
LSBB is responsible not only for the
tendering of construction projects, but also
for inspections during the construction work.
In addition to inspections of the asphalt
mix during paving, selective core samples are
taken when the project is complete. These
samples are used, among other things, to
determine compaction levels and test the
quality of the road.
The new Moba Pave-IR Scan system
measures the temperature over the entire area
during paving. Using this data, it is possible to
draw conclusions about possible weak points
in the road, according to Moba.
