– Concrete Pavements for Roundabouts &
Intersections
Pavements within turning areas such as intersections
and roundabouts are subject to very high shear
forces from the tyres of vehicles, especially
trucks.
Horizontal
loads from the outer tyre imparted on the pavement
during a tight turning movement are as much
as 80% of the static load. This turning load
causes surfacing and base shear failures in
thin surfaced granular pavements. As a result,
intersections and roundabouts of traditional
granular pavement construction need regular
reconstruction.
Concrete
pavements at intersections and roundabouts will
prevent surface and base failures, as well-designed
and constructed concrete pavements will last
at least 40 years without needing reconstruction.
Consequently the life cycle costs of concrete
pavements are lower than traditional granular
pavement.
This IB
describes the benefits and use of concrete for
roundabouts and intersections. Download.

IB89
– Cement Stabilisation
Over the last ten years heavy vehicle traffic
in New Zealand has doubled, putting increasing
demands on our road pavements. As a result,
more pavements now fail before they reach the
end of their design life. Cement stabilisation
is one method to prevent these failures.
Cement
stabilisation is an ideal method to enhance
the properties of marginal materials so that
they can be used instead of premium quality
aggregates even in the highest stressed areas
of a pavement.
Although
cement stabilisation has been used for over
60 years in New Zealand, improvements in stabilising
equipment have led to a recent resurgence of
interest.
|
In response, specifications are changing to
acknowledge and allow innovative uses of alternative
materials and plant to produce cement stabilised
mixes that are suitable for highly trafficked
roads.
This IB
outlines the principles of cement stabilisation,
including in-situ and plant mix processes, modified
and bound materials, and the principles of designing
stabilised pavements. Download. |

ICCX
Oceania - Sydney, March 09
The International Concrete Conference & Exhibition,
ICCX Oceania 2009 will take place on March 30
- April 2, 2009 at the Sydney Convention and Exhibition
Centre, Sydney, Australia.
Organised by the publishers of the trade journal
CPIworldwide.com, with the support of concrete
associations from Oceania, this international
event will bring together speakers and exhibitors
world wide.
As with previous ICCX events, organisers have
responded to the local industry’s needs,
and carefully selected more than 20 relevant and
interesting speakers for the conference program.
The speakers will share their experience through
a series of presentations pertinent to current
industry needs.
|
 |
A trade exhibition
with more than 80 exhibitors from around the globe
will showcase the latest developments in concrete,
concrete products and precast concrete industry.
As an introduction
to the conference program, two technical courses on
the production and application of self-compacting
concrete, and the design and production of precast
concrete will be held on March 30.
The ICCX Dinner
Party, held on March 31 aboard a boat cruising Sydney
Harbour, will offer plenty of opportunity for networking
and socialising.
On April 2, following
the two-day conference and exhibition, delegates are
offered the chance to tour a range of precast plants
across Sydney to view modern production techniques
and practices.
Anyone who is
involved in the concrete industry should take this
unique opportunity to learn more about the latest
developments in concrete technology worldwide. This
is a must-attend event. As such, CCANZ
has arranged for members to receive a 10% discount
on exhibition stands and registration.

Research
Demonstrates Importance of Cement & Concrete to NZ
Economy
Research into
the importance of the cement and concrete industry
to New Zealand’s economy has found it contributes
nearly $3 billion towards GDP.
A New Zealand
Institute of Economic Research (NZIER) report shows
that for the year ending March 2006, the value of
the industry’s output was $7.4 billion. This activity
supported 24,000 jobs and created a value add of $2.8
billion – about 2% of New Zealand’s GDP.
CCANZ chief
executive Patrick McGuire believes the research illustrates
just how significant the cement and concrete industry
is to the nation’s economy. “A primary aim for us
is to ensure that cement and concrete are truly sustainable
– environmentally, socially and economically. The
NZIER research proves the industry is more than meeting
the economic part of this objective,” Mr McGuire said.

Brewery Project
Takes Out First Ever Cement & Concrete Industry
Sustainability Award
A unique building
project using considerable quantities of recycled
waste glass won the inaugural 2008 Concrete3
Sustainability Award in Rotorua on the evening of
Friday 3 October.
Project Century,
a brewery currently under construction in South Auckland,
is a joint submission by Holcim (New Zealand) Ltd
and Mainzeal Property & Construction Ltd for Lion
Nathan. The project will use recycled waste glass
as aggregate in the building’s concrete structures,
and is due to open in 2010.
The award, which
is part of the Concrete3
initiative launched last year by the Cement and Concrete
Association of New Zealand (CCANZ), acknowledges companies
whose product, programme or initiative demonstrates
excellence in environmental, economic and societal
sustainability.
The runner-up
in the Concrete3
Sustainability Award was Wilco Precast Ltd, for Sinclair
House in Whitianga – an energy-efficient holiday
home understood to be the first house in New Zealand
built entirely from lightweight precast pumice concrete.

Concrete Barriers Safest Option
CCANZ Chief Executive,
Patrick McGuire, recently outlined the advantages
of concrete road safety barriers over the currently
preferred wire rope option, in New Zealand two most

with Clause H1 – Energy Efficiency
The New Zealand
Building Code (NZBC) Clause H1 has as its objective
the efficient use of energy in buildings. The performance
requirements as they relate to housing and amended
on the 13 August 2007 are, ‘Buildings must be constructed
to ensure that their Building Performance index (BPI)
does not exceed 1.55’.
