EUPAVE's Dutch member Cement&BetonCentrum organized on the 10th of October the Dutch Concrete Road Symposium in ‘s-Hertogenbosch.

The theme of this Symposium was: ‘Knowledge from the source’.

MEP, Mr. Peter van Dalen, vice-chairman of Committee of Transport and Tourism, was invited as one of the key-note speakers. Mr van Dalen addressed the audience with the EU-topics on EU Transport policy.

Related to the costs of infrastructure he challenged the concrete sector to design and construct innovative infrastructure with good price/quality balance and low maintenance. Mr van Dalen also pointed out the plans for the Trans European Network (TEN-T) for which 1 billion euro will be available for co-financing. In this perspective the current  LCA period of 25 years, according to Mr. Van Dalen, must be extended to a much longer period.
For reducing road fatalities separate and safe infrastructure is needed for vulnerable groups like pedestrians and cyclists.
To improve the safety of traffic, investments in maintenance remains necessary, but also improving 'slip'-resistance (skid-resistance) and safety barriers, especially for motorcyclists.
Traffic safety is one of the main priorities at national and international level!

The second key-note speaker was Mr. Robert Rasmussen, expert on surface characteristics  from The Transtec Group Inc. from the USA.  Mr. Rasmussen at first pointed out the technics to measure surface characteristics and the relation between friction and noise. He presented the variability of tested textures of hundreds of miles in 20 states and 7 countries. Conclusion: there is a lot of variability from project to project, but also within projects! The variability can often be explained by the consistency of the concrete mixture and the attention for the execution. Noise measurements on the same surface texture can differ up to 8 to 10%!

Mr. André Burger, Managing Director of the Cement&BetonCentrum  compared in his presentation the CO2-footprint of Dutch cement with worldwide used cement. The worldwide cement production is responsible for about 5% of worldwide CO2 volume. For the cement used in The Netherlands Mr. Burger presented a calculation that showed a CO2-footprint of 1%. So this 1% should be used in calculation programmes related to life-cycle studies for concrete in infrastructure in The Netherlands.

In the final presentation of Marc Eijbersen of CROW the start of a Knowlegde Platform for Concrete Pavements was announced. The Cement&BetonCentrum has taken the initiative to start-up such a platform to exchange knowledge between principals, consultants and contractors.
