bauma 2007
bauma presents the
latest development in cold-recycling technology
Munich.
Renovating asphalt pavements using cold
recycling is becoming more and more important,
especially in western industrialised nations.
This environmentally-friendly process saves
resources, in that it turns the old road surface
into a new one, using all of the salvaged
material. The latest developments in this area
will be on show at bauma 2007, the world´s
biggest international trade fair for machinery
for the building and construction,
building-materials and mining industries, which
takes place from 23 to 29 April 2007 in Munich.
In cold
recycling technology there are basically two
methods – in situ or in plant. In the in-situ
technique a cold recycler fitted with a milling
and mixing rotor recycles the surface layers in
just one pass. During the milling or mixing
process, water and liquid binder are added,
along with bitumen emulsion, foamed bitumen or a
cement suspension. The new surface is then
simply compacted and the new structural and base
layer is ready. With the in-plant technique the
material previously recovered is mixed in a
cold-recycling mixing plant (generally mobile),
then relaid and compacted. Work proceeds here in
several stages.
In both
methods the choice and composition of the
binder, and the mixing process itself, are
critical. Before relaying the milled material,
it first has to be mixed evenly with water and
the various aggregates. The aim is to achieve
maximum homogeneity and mix quality. This is
essential for a high-quality result.
Presented at
bauma will be innovative solutions for further
increasing the performance of foamed bitumen
spraying systems. State-of-the-art control
systems ensure maximum accuracy and reliability.
Also on show will be new, improved milling and
mixing rotors. New rotor designs help further
optimise the granulation and mixing processes.
Integrated moisture sensors give better control
and regulation when adding water.
With the
mobile and stationary cold-recycling mixing
systems used in the in-plant process, visitors
can also expect some productivity improvements.
The performance of the twin-shaft paddle mixer
has been further improved, along with mix
quality. The shape of the mixing blades and arms
has been further optimised, resistance to wear
improved and the emptying times reduced. Full
use is being made of the synergies deriving from
the integration of mechanics, electronics and
computer technology. Visitors to bauma in April
in Munich can look forward to a full review of
current developments in the field of
cold-recycling technology.

The
world´s biggest international trade fair for
machinery for the building and construction,
building-materials and mining industries takes
place at the New Munich Trade Fair Centre from
23 to 29 April 2007. This event, organised by
Messe München GmbH, will take up over 540,000 m2
of indoor and outdoor exhibition space. The last
bauma in 2004 attracted 2,801 exhibitors from 47
countries, all making full use of the fair as a
platform for communication, product presentation
and marketing. 50% of the exhibitors were from
countries outside Germany. 416,000 trade
visitors came to bauma in Munich in 2004, 29% of
them from abroad. The number of exhibitors and
the number of global brands among them is
evidence of bauma´s central significance as an
international forum for the sector. 93% of the
exhibitors at bauma 2004 reported contacts with
international trade visitors at their stand.
