–
What are the volumes and uses?
What do our customers require?
What about the reputation of our techniques?
Is technical knowledge an issue?
How do the techniques fit with the market?

What is IBEF?
• International Bitumen Emulsion Federation
• An association that gathers national associations
dealing with asphalt emulsions
• Individual members from countries with no
association
• IBEF represents more than 70% of the emulsion
volumes worldwide

A worldwide survey across IBEF members
• The national association
– Members, market share,
• The market
– Pavement preservation
• The reputation
– Communication and awareness
• The technical knowledge
– Contractors, engineers, owners
• The techniques
– Do they fit with the market
10
A worldwide survey across IBEF members
• 19 questionnaires
• 10 answers
• Comments
– Various situations
– 2 common topics
• Lack of funds allocated to road maintenance
• Good reputation of the asphalt emulsion
11
National associations
• A variety of associations
• Members
– From 8 (Japan, UK) to 230 (Italy)
• Market share
– Usually 75% - 100%
• Some associations report how many plants that are operated
within their country (UK, Japan, France)
12
The market
• Do we know our market?
– Volumes, uses
• Yes we do
– Japan (every month), UK & France (quarterly)
– France & UK reports to differentiate spraying / mixing emulsions
• No we don’t
– USA, Australia
• We estimate
– Mainly in countries where there is no association (100 countries
investigated for the 2010 WOE)
– Industry, suppliers & traders: emulsifiers, liquid asphalt, equipment

The market
• Do we know our market?
– Volumes, uses
• Yes we do
– Japan (every month), UK &
France (quarterly)
– France & UK reports to
differentiate spraying / mixing
emulsions
• Data collection through an
intermediate independent
third party
• An attempt in the USA
14
The market
• Emulsion is mainly designed for maintenance works
• Road maintenance = pavement preservation
• Level of owner awareness
– Low in emerging market where the focus is on new construction
– Fair in most of mature markets; lower attention at local level
– High in countries such as Australia and in Korea where PMS is
implemented
– Politicians do not pay enough attention
• Politicians
– Politicians do not know the value of road assets
– In the USA, “pavement preservation is included in the transportation
bill now being debated in the Congress” (FP2)

Emulsion is mainly designed for maintenance works

Conscientiousness of road owners
Politicians
Allocated funds
– Insufficient…
– South Africa: “Central Treasury now insists on road authorities having
a PMS in place prior to allocation of funds”
– India: “excise is imposed on sale of petrol and diesel. This money is
used for pavement construction and preservation”
16
The market
• Allocated funds are insufficient
– Volumes are shrinking
– Hot mix asphalt volumes are decreasing

The market
• Allocated funds are
insufficient
– Japan: -50% v/s 2000
– France: ¼ of the needs for
national roads
• Needs for road maintenance
are constant, increasing
• “More for less”
• A real challenge
• How can the asphalt
emulsions industry address
this challenge?
19
The market challenge
• Allocated funds are insufficient
• Use the right technique in the right place

The reputation
• Feedback from the enquiry is good
• High credibility brought by the CME (World Congress on
Emulsion) and WOE (World Of Emulsions) since 1993
• In Europe: increased credibility through the CE marking
(factory production control)
• But still a lot of work to do, and the backdrop is constantly
evolving
25
The reputation
• “Engineers and contractors are well informed and aware”
(South Africa)
• “Engineers at the federal and state agencies know about
emulsion as a concept, some know the details. This is not the
case with many local agencies” (USA)
• “Most of [road engineers] have known that the asphalt
emulsions are used only for tack coats” (Korea)
• “Basically, they understand the concept of asphalt emulsion”
(Japan)
26
The reputation
• “Yes but it is still a battle, partly as the client has become
more fragmented moving from mostly local & national
authorities into outsourced consultant & contractor
management of the network” (UK)
• “Due to the turnover of road engineers in the road
stakeholders, we have to train and educate the new
generation” (France)
• A never-ending story!
27
The techniques
• In mature markets, the main uses for emulsions are surface
treatments, typically chip seal and micro surfacing
• Organic growth will come from mixes and recycling
28
The techniques
• No technique has ever been prohibited for use after a
technical failure
• The market is demanding
– Long term texture depth for micro surfacing
– Lower noise chip seal
– SBS modified emulsions to counter the use of hot applied modified
binders (South Africa, Australia)
– Trackless tack coats
– Emulsion based mixes for wearing course and base course
– Sustainable solutions
29

Chip seal
• Strong development of the
use of modified emulsions
• Development in Europe
chip seals in Germany
chip seals in the United Kingdom

Conclusion: the role of IBEF
• To provide assistance in structuring teaching courses (Italy)
• To spread the word & be as effective as possible (UK)
• To keep its members informed of the latest technological
developments and trends and growth of emulsions in global
markets (South Africa)
• To introduce (share) information about the new trend and
techniques of asphalt emulsion in the world (Japan)
• To give more and more inputs on newer applications of
emulsions (India)
32
Conclusion: the role of IBEF
• Trends and ideas for the future (Australia)
• To continue to promote the use of emulsion by being an
international platform for exchanging our best practices
(France)
– Cape Seal
– Grave emulsion
– Emulsion for railway tracks
South Africa
France
Japan
33
Conclusion: the role & the future of IBEF
• IBEF is and will
be what its
members want
it to be and to
become
• A new logo, a
new web site
