Big success and beat the records ...


More than 1000 participants from the asphalt and bitumen industries from 5 continents met in Istanbul, Turkey on 13 - 15 JUNE 2012.

The 5th E&E congress with the theme “Asphalt, the sustainable road to success” will be remembered as the most  important and the ‘unforgettable’ one in its history. It was the platform where the asphalt and bitumen industries were about to move to a point where traditional thinking changed and a new era will be embraced where Warm Mix Asphalt and other technologies of our industry will help shaping the future of the coming years regarding the technical, health, safety and environmental issues.

The wealth of presentations, the moderators’ reports in the technical sessions, the exhibition and the poster session provided an excellent overview of where we are now and where we are going to.

Also the social events in Istanbul, where 2 continent meet, gave the participant very nice and unforgettable memories.

Some numbers

With more than 820 registered Congress delegates, this number was higher than the previous congresses in Copenhagen and Vienna. In total more than 1000 participants (including exhibitors and accompanying persons) came to Istanbul for the Congress.

With 267 accepted papers we almost had an all-time record of congress papers; we just had 2 papers less than the record of Barcelona in 2000.

But we had the biggest exhibition ever (67 different companies with 963 m2 exhibition space) and the largest poster session ever (with 163 posters)! We also had more sponsors and more received abstracts (391) than ever before. So all in all it was a great success.

Opening Session of E&E

On 13 June 2012 the Congress started with the Opening Session, which was chaired by Simon van der Byl.

In this session there was:
  • A welcome to the Congress by Alberto Madella, President of Eurobitume
  • A welcome to Istanbul by Gülay Malkoç on behalf of the Mayor of Istanbul
  • A welcome of the Minister of Transport, Maritime Affairs and Communications of Turkey :
    Mr. Binali Yýldýrým
  • A speech and Award Ceremony by Jean-Louis Marchand, President of EAPA.

Welcome of Alberto Madella President of Eurobitume


In his speech Alberto Madella mentioned that sustainability has become an overarching theme of this congress, probably the fundamental one, touching all aspects of what we do.

Some elements of his speech are: Roads were and still are the base of civilization which has also continued to develop, including the demands that drive our social, environmental and economic needs, including the freedom to travel. Now the common thread through these demands is a desire to be sustainable in our development. It is therefore relevant for our industry that managers reflect on suggestions from our Congress Sessions about the future of their business. For the bitumen and asphalt industry to be competitive and play its role in maintenance and development of the transport infrastructure, we need to involve stakeholders, when sustainability has become the driving concept for everybody in private and public sectors.

During last 20 years our industry responded to high traffic growth, and particularly to lorry traffic growth with new products, improving stability and resistance to deformation. When noise became a major concern, our industry developed special binders, able to support special new applications by contractors, to satisfy authority’s environmental requirements. Now the modern asphalt roads last longer and may be considered also “environmental friendly roads”.
 
Despite the economic downturn, the increased pressure to improve air quality and reduce greenhouse gas emission has been translated by our industry in continuous investment for new technologies, to target a reduction in CO2 emission during production and application, because CO2 emission legislation is not limited to the automotive market, but also deeply impacts the refining sector in the context of emissions during fuels and bitumen production.
 
In parallel with sustainable growth, we should also mention the efforts of bitumen and asphalt industry in occupational and health and safety aspects, which were always an important aspect for our industry.

Today our industry is operating under the well-known REACH legislation. REACH requires that each substance manufacturer is responsible for the assessment of workers’ risk for exposure to the substance. It is a responsible approach and the bitumen and asphalt industries have promoted several robust scientific studies on bitumen fume to evaluate the health implications of such exposure.

A new era heralds Warm Mix Asphalt and other technologies at the forefront of our industry, helping shape the future for the years to come.

Welcome to Istanbul

Message from the Mayor of Istanbul Dr. Kadir TOPBAÞ (by Gülay Malkoç)

The Mayor of Istanbul mentioned in his message that he expressed his great pleasure in having this congress in Istanbul. Istanbul is the face and window of Turkey to the world.

It also mentioned: We have been investing in every corner of the city in an “effective, efficient and balanced” way just as our vision requires.

We have invested 52 billion Turkish Liras in the last 8 years with this understanding. We have allocated 24 billion Turkish Liras out of this amount for transportation such as intersections, roadways, tunnels, asphalting and rail systems which are revolutionary services to be operated.

ISFALT is one of our affiliates that made serious contributions to these works.

ISFALT was established to meet the asphalt needs of mainly Istanbul Metropolitan Municipality and our 39 district municipalities. In terms of production and performance figures, this affiliate of ours has managed to become one of the largest companies of not only our country but also Europe. ISFALT maintains its production activities with a  state of art quality policy in four factories.


Welcome of the Turkish Minister of Transport, Maritime Affairs

and Communications; Mr. Binali Yýldýrým


The welcome speech of the Turkish Minister of Transport, Maritime Affairs and Communications was more than 40 minutes and it was really an excellent and inspiring speech from the beginning to the end. Several congress participants wished they had a Minister of Transport like Mr. Yýldýrým. Instead of giving a summary of his speech in this EAPA Newsletter the entire English translating of the speech of Mr. Binali Yýldýrým can be downloaded from the EAPA website. It is really worth reading this entire speech (even if you heard it during the congress) and it  might be useful for you to distribute it further.

Speech and Award Ceremony

by Jean-Louis Marchand, President of EAPA


In his speech Jean-Louis Marchand started with thanking to the Minister for honoring the Congress. Then he continued with a short description of the activities of EAPA with organizing this Congress being one of them.

Some quotes of his speech:

Performance
Today in Istanbul, we are at a point where traditional thinking has to change. Road construction techniques have become increasingly sophisticated. They offer the possibility of choosing between such priorities as cost, preservation of resources and energy savings, according to the life cycle. Companies develop tools for their clients in order to compare different variants. Companies are able to do more with less. But they have to be challenged, and they must be free to submit innovative offers. “Clients” have to express what they really want, but they have no indicators to measure and describe performance and the level of service delivered by roads or related infrastructures.
 
It becomes a duty for both companies and professional associations to help the “owners”, generally local administrations, to inform the end clients about what can really be built, for what price, and with what service. But key performance indicators are now indispensable to describe what is achievable with the available funds. We have to work on this.

Bitumen
Will it still be possible in the coming years to access desired quantities of bitumen, in affordable conditions?

Asphalt, therefore bitumen, will be necessary, even if technical progress and recycling permit savings. Dialogues with oil companies are needed to be sure that refineries still produce and sell bitumen in the future, and at a reasonable price.

Bitumen has a great advantage over petrol, diesel, gas or heating oil: when used, the carbon molecule remains in the bitumen; it does not create a molecule of C02! Except in chemical uses, this is the only use of oil that does not emit CO2.

Warm Mixes
During the E&E Congress in Barcelona in 2000 Peter Rothwell, former President of the EAPA, spoke a lot about CO2 emission, and about the energy consumption within bituminous pavements. He pointed out that the most effective way of reducing emissions is to lower the temperature at which asphalt is made. He said that this process has the added advantage of minimizing asphalt fuming.

Now there has been strong competition between companies, each one trying to reach the lowest temperature. There are, for the time being, dozens of different ways to produce warm mixes in Europe, between 90 and 140 Celsius degrees; dozens! But: we have not been able to choose together which ones we wanted to develop, we have not been able to explain to clients what the advantages of the warm mixes are, we have not been able to adapt our equipment to produce with competitive costs.

Warm Mixes in the USA
In short, we have not been able to develop a common European strategy: we have to learn from this. It is interesting to compare with what happened in the US.

Some American friends came to Europe in 2002. They discovered the warm mixes we had invented. They understood immediately that it was the right answer to reduce fumes.

They knew that below 135 C°, there are no longer fumes; no fumes, no irritation; they decided to equip all their asphalt plants with the required devices for introducing foam. And if needed, if requested by clients, they are able to produce warm mixes at lower temperature through other methods. They produced about 100 million tons of warm mixes last year, 30% of their production, while in Europe we produce less than 2% of warm mixes. As a matter of fact, USA and Europe did not have the same objectives: in Europe, we were obsessed by cancer or by the CO2 emissions, while Americans focused on the irritation due to the fumes and worked on the well-being of employees.

IARC Monograph

The main achievement of the EAPA in the last twenty years was being involved in organising and participating in the studies designed and managed by the IARC, International Agency for Research on Cancer, which is part of the United Nations World Health Organisation. It started when Max Von Devivere was General Secretary of the EAPA, in the mid-nineties, with a joint undertaking by EAPA, Eurobitume and CONCAWE (the European Oil Companies organization for environment, health and safety).

It continued with a second study, jointly with the NAPA (National Asphalt Pavement Association, National means American) and the Asphalt Institute. Results of the studies were available at the beginning of 2010. They played an important role among the hundreds of studies used by the IARC for updating the monograph of bitumen.

The previous monograph dated from 1987. You know that the IARC session working on the update took place 8 months ago, in Lyon. The decision has been published, but we are still waiting for the final report, explaining the decision, and expected for the end of this year.

I hope that you will be aware of what has been done to prepare the monograph, and to obtain a decision adapted to our asphalt business. A lot of work has been done and numerous exchanges were organized in 2011, following what had been produced for years inside the BIHF, the Bitumen International Health Forum. We should thank many people for the job they did, and we do, but we the EAPA wanted to give a specific award to 4 people for the performance they provided, and for three of them, for the job they did during one week in Lyon, as “observers”, official or not, observers of the work groups of experts created by the IARC, to make the decision. Thanks to their commitment and expertise, we have obtained a manageable decision. The keys to the whole process were transparency, competence, ability to work with the academic or scientific communities, the desire to understand what the others were saying and to explain what we know and why.’


Award Ceremony


After his speech Jean-Louis Marchand invited Mike Acott, President of the NAPA, Henri Molleron, Head of Environment and Sustainable Development with Colas, Tony Riley (BP) and Philippe Dewez, General Manager of Eurobitume to come to the stage and he thanked them for all the work they did in Lyon and gave them a token of appreciation of the work they did.

Congress Sessions

On the first day there were two Keynote Speaker sessions where a total of eight eminent experts gave their vision on one of the key issues that was addressed by the congress.

After the Opening Session and the keynote Speaker sessions, the “Technical Sessions” started with paper presentations and the moderators’ reports.

Until the last day and last moment most of participants were in the auditorium of the congress hall, which showed the great interest.

Summary and conclusions of E&E congress 2012

During Closing Session Egbert Beuving, Director of EAPA, presented a summary and conclusions of the presentations made during 3-days of the Congress. His presentation will be used here to give a short sumary of the highlights of the 5th E&E Congress:

Social impact / issues
Prof. Dr. Mustafa Karasahin, Civil Engineering Department in Istanbul University, Turkey summarised that a good road network is essential for the development of regions and the asphalt industry has their challenges to create more sustainable pavements and to lower rolling resistance.

Social economic impact
Vilrid Femoen, Director of Policy, Norwegian Road Federation, Norway mentioned that the effects of road investments on national goals must be included and estimated in desicion-making considerations, i.e. in the cost/benefit analysis.

Financing of road infrastructure + maintenance
André Broto, Vice-President of Cofiroute France concluded that public or private, the concession system has shown its success for a fair financing system of sustainable road infrastructures to provide high level of services.

Next to that Road Asset Management should get more attention of the politicians. The road owners should take care of their assets.

Getting the right message: communication and social media
Siobhan McKelvey, Marketing Manager - Nynas Bitumen encourage people to use Social Media to get their message heard.

Improving Health & Safety
Henri Molleron informed the Congress about the IARC monograph and how it went. He explained what the new IARC monograph means for the asphalt business, what the consequences could be both for companies and for professional associations, and why we will speak more and more about the Penetration Index of bitumen. Carl Robertus, Global bitumen technology manager, BP, Germany summarised: For population bitumen is and will remain safe. When used correctly, working with bitumen and asphalt is and remains safe for the workers For the health of the people living along roads we can improve their health and well-being by reducing the road noise by applying noise reducing asphalt pavements. During the congress several new products were presented like the Germain LOAD (Noise Optimised Asphalt Surface Layers), Porous Mastic Asphalt, SMA LA (Low Noise) and the French open-graded asphalt concrete 0/4mm. Also the durability of noise reduction and durability of low noise road surfaces was discussed.

Energy & Carbon
Jan van der Zwan, DVS, The Netherlands mentioned: Yes, we can…….. reduce the carbon footprint of roads. In Session 4 it was mentioned that Sustainability is more than environment only. There are 3 pillars: environment, society and economy, which should be in balance. To reduce carbon emissions we have to work on: better energy efficiency, durable pavements with long life (high quality pavements) and recycling. Several examples were shown to reduce energy and sustainability should be seen as a challenge not a threat.



Adapting to climate change

Rudi Bull-Wasser, BASt, Germany mentioned that technical solutions are available to deal with climate change; make use of climate analogues to import from elsewhere. They only need is focus on adhesion and durability (water sensitivity) because of the changes in rainfall / water amount.

Resource use & recycling
John Barritt, WRAP (Waste & Resources Action Programme), UK showed:
  • The road in the EC Roadmap to a resource efficient Europe is constructed with asphalt
  • Asphalt is 100% recyclable; Waste legislation: Stimulate use RAP
  • Better & optimal RAP management is needed to fully use the recycling potential
  • Use of “waste” of other industries: Be careful
  • Asphalt is not trashfalt. Look at all the consequences, for now and the future.

Green or Sustainable Procurement
Shamir Ghumra (Aggregate Industries) explained that Green or Sustainable Procurement represents an opportunity for the asphalt sector. We have Warm and Lower Tempeperature Asphalt. This technlogy gives energy savings, it is beter for the environmental and its work occupational benefits are now widely recognized. Warm Mix asphalt was invented in Europe and it is now widely used in the USA. The main topic is now the performance of WMA mixes compared to HMA. We need to evaluate the quality improvements at reduced ageing temperatures. The techniques are avaiable noe and we have to start now to get experiene and to learn by doing.

Durability & Performance binders session
In this session the importance of robust testing techniques was shown. We now have a wide range of modifiers & new promising additives avaiable. There was an increased interest in MSCRT test and new devices and techniques to measure fatigue, fracture & thixotropy were shown. Work has to be done on long-term laboratory ageing and a better binder characterisation is needed as well as a validation with mixes. Performance Related bitumen standards are needed to be able to implement the advantages in practice.

Durability & performance - mixes
The conclusions of session 8 were: Perpetual asphalt base courses can easily be built when using a high % of RAP. The use of RAP gives economical benefits. Thinner structures, a longer lifetime of the asphalt layers, a better quality and reducing the risks of premature failures by a better monitoring and control of the laying process by the contractor contribute all to a better sustanability.

The importance of production, laying and approval systems for obtaining a good performance were stressed. In short the papers of session 8 give the foundation for the sustainable road to success.

Concluding remarks

  • Asphalt is the sustainable road to success
  • Asphalt is 100% recyclable
  • Asphalt can be made more sustainable by reducing the risks of failure and by providing a high(er) quality, at reduced production and paving temperatures
  • Sustainability is a real challange that can be realised by using the techniq ues and knowlegde presented here in Istanbul
  • Road Authorities: If you want a higher quality: Ask for it
  • We have to move forward and we need to change attitude to move forward

Beuving concluded with stating that we can do all these things, but we should stop with thinking “Yes we can”; we just have to do it !

This also applies for Warm Mix Asphalt. Warm Mix Asphalt is the future. You have to start now in order not to miss the boat in the future. So do it!

Closing speech of Jean-Louis Marchand

In his closing speech Jean-Louis Marchand thanked all participants for coming to Istanbul and he also thanked all the organisers for organising this successful Congress. He also mentioned: “After these days, if we should choose only one priority, if only one conviction should remain, I would say that we must really do our best to reduce the temperature of the uses of asphalt, because:

  • it saves energy
  • it limits the CO2 emissions
  • it cuts the costs
  • it avoids or reduces the bitumen fumes.

‘Asphalt, the sustainable road to success’ was the title of the Congress. I would conclude by saying that the reduction of the temperature is for asphalt the only sustainable way to success”.



Photo contest


All E&E 2012 Congress participants were invited to participate in the Photo Contest by sharing their favourite photograph demonstrating asphalt roads and/or bitumen. More than 45 pictures were exhibited in the exhibition area. The winner of the best photo was selected by participants. The winner of the Photo Contests was Suha ARAY and he won an iPad 3 with his picture.

Best poster award

On the second day of the Congress there was a special “Poster Session” where the authors of accepted papers had the possibility to display, discuss and share further information regarding the content of their paper with interested participants of the Congress. The Posters were displayed on the lower exhibition level and they provided in an excellent overview of the key points of the papers.

There was an award for the best poster and Henny ter Huerne (the Netherlands) received the Best Poster Award from Mike Southern (Eurobitume) in the Closing Session of the Congress.



Social Events


Cocktail Prolongé
The Congress gala event, the so called “Congress Cocktail Prolongé” was held on of the first day of Congress in the beautiful setting of the Sait Halim Pasha Mansion (www.saithalimpasa.com), just in front of Bosporus. Two large boats brought the congress participants from the congress area to the Sait Halim Pasha Mansion after a 1 hour boat trip on the Bosporus with the guide.

Around sun-set time; the participants and the accompanying persons (more than 1000 in total) were welcomed in a very historically way by the waitress of the mansion when they stepped on shore.

In the Sait Halim Pasha Mansion the quests were served with a full open buffet dinner and drinks. The nice music and the beautiful view on the Bosporus and Asia made this is a unique and unforgettable event.

“Sundowner” reception
On Thursday 14th of June there was a “Sundowner” reception immediately after the Congress sessions on the sun terrace above the exhibition hall with a spectacular view on Istanbul. A very famous and historical Turkish Band played as entertainment for the congress participants.

Sponsors of the E&E Congress

Many companies sponsored the E&E Congress. A special sponsor of the congress was the Turkish Asphalt Contractors Association (ASMUD). ASMUD formed a pool to bring participants from the government side to congress. In this way more than 120 participants from the General Directorate of Turkish Highways and academics from Turkish state universities were able to attend the E&E Congress and to present their posters.

Congress Proceedings

In the Congress proceedings with the 267 accepted congress papers, the keynote presentations and the moderators’ reports as well as copies of the PowerPoint slides that were presented during the presentations are available on a USB sticks for persons that could not attend the congress.

The costs of the USB stick are € 25,- (including mailing costs) and can be ordered at the E&E congress secretariat, EAPA secretariat or the Eurobitume secretariat.
