The Cement&BetonCentrum organized on the 11th of October 2011 the Dutch Concrete Road Symposium. The last time such an event was organized was 13 years ago.
Over 220 participants subscribed for this event and this was more then expected. The interesting programme and also the indoor- and outdoor exhibition was credit for this. In front of the venue a concrete bicycle path was constructed and even a brand new slipformpaver was present.

EUPAVE was also present in the exhibition as a guest of the Cement&BetonCentrum.
The programme including parallel sessions had a broad range of subjects. The main part was dedicated to presentations on sustainability. In the parallel sessions the more technical issues and applications were presented such as Roundabouts, Container terminals, Bicycle paths and Buslanes, but also subjects as Optimized Exposed Aggregate Concrete and slab length of fibermix concrete pavements.
Several new brochures were presented.  These can also be found on the website of EUPAVE (here).
All presentations are available on the website (

Only one week later, on 20 and 21 October, it was the German Road Research Association FGSV who organised the two-yearly “Betonstrassentagung”.  About 350 participants met in Cologne to listen to very interesting and clearly presented topics such as exposed aggregate concrete, whitetopping, truck parkings, dowel alignment, concrete safety barriers and many others.  Particularly worth mentioning was the contribution of Mr. Jens Skarabis from the Technical University of Munich about the assessment of the first and second curing of exposed aggregate concrete surfaces.  He was granted the Road Construction Research Award from the Otto-Graf-Foundation.  The numerous ongoing studies and research projects and the detailed guidelines and specifications resulting from them undoubtedly contribute to the high quality of the German concrete motorways.



Upon invitation of Fabio Miseri from our member AITEC, the Italian Cement Association, Luc Rens acted as a central guest in a round table debate that took place on 7 October '11 in the framework of the SAIE International Building Exhibition in Bologna.

A discussion, moderated by Mr. Marco Liconti - Italian news journalist, was set up around 12 statements related to concrete pavements and sustainability.

Very soon, an exciting interaction was created amongst the more than 40 attendees representing public authorities (national road authority ANAS, regional road authority Veneto Strade and local road authority province of Bolzano), designers, academics, contractors, material and equipment suppliers.  The issues varied from very technical, e.g. about concrete mixes, to economical and societal.  A particular topic was how getting started with construction of concrete roads what made clear the importance of international associations such as EUPAVE in the dissemination of experiences and good practices.


BRITPAVE'S 20th ANNUAL DINNER and SEMINAR was held in SAVILL COURT HOTEL, 26-27 September 2011

2011 is Britpave's 20th anniversary year. This year Britpave Annual Dinner and Seminar took place in Savill Court Hotel, Surrey, UK. 

The seminar was opened by Britpave's Chairman Dr.Jim Troy and the speakers from UK, America and Europe were invited to the scene.
Amongst other very interesting presentations, Mr.John Roberts, International Grooving & Grinding Association, gave a speech on diamond grinding, drawing attention to integrating engineering, economics and the environment. Mr.Mark Smallridge, Nigel Nixon & Partners Inc., presented experiences on roller compacted concrete pavements for mobile container terminals and other American Ports. Concrete barrier was mentioned by the UK Government Security Advisor from the Centre for the Protection of National Infrastructure from "a robust defence system" point of view.

The drink reception, dinner and the coffee breaks provided platform for networking, and EUPAVE was represented in the exhibition area.



From 1 to 3 August '11 a delegation of the International Society for Concrete Pavements (ISCP) and EUPAVE visited Sydney to take part in a three day programme of interaction with the Australian Society for Concrete Pavements (ASCP). 

Day 1 consisted of a well-prepared and -documented field inspection tour with a visit to a part of the Pacific Highway, north of Sydney.  It was a great occasion to learn about the Australian experience in highway construction and concrete roundabouts.  The major activity on the programme was the Concrete Pavements Conference, attended by over 100 delegates and in which ISCP and EUPAVE shared American and European experiences with their Australian colleagues.   Managing director Luc Rens also reported on the history and activities of EUPAVE.  Aniceto Zaragoza, president of EUPAVE met his colleagues Mark Snyder (ISCP) and Mark Hoskins (ASCP) in an informal meeting during which further collaboration, exchange of technology and the possible organisation of videoconferences was discussed.  As a conclusion it is clear that we are all dealing with the same issues, facing the same challenges and that all parties benefit from the discussions and the sharing of knowledge and information.


6 July 2011

A jobsite visit to the “RECONSTRUCTION OF THE MOTORWAY E17 IN CRCP” (continuously reinforced concrete pavement) was held on 06 July 2011.  It was a co-organisation of the Belgian Road Association, the Belgian Cement Association FEBELCEM and EUPAVE.

Some 35 participants gathered in Maaltebrugge Castle near Gent.  After a lunch, Luc Rens, Managing Director of EUPAVE opened the seminar and gave the floor to Mr. Peter De Backer, Head of the Roads and Traffic Division East-Flanders who welcomed the participants.  He gave an overview of the infrastructure he is in charge of in the province of East-Flanders and mentioned a series of large motorway rehabilitation projects that are planned in the coming years and which mainly deal with concrete pavements.  The aim, as expressed by the Flemish Minister of Public Works  Mrs. Hilde Crevits , is to make up arrears by 2015 with regard to the quality of the Flemish motorway network.  The ongoing project on the E17 is part of this rehabilitation programme and it is one of the largest projects in Belgium at this moment.

Mr. Gorik De Koker, Project Engineer, Roads and Traffic Division East-Flanders presented the worksite. The reconstruction of the motorway E17 is 11 km in totally of which 9,9 km CRCP (25 cm) upon a sandwich layer of asphalt ( 5 cm) and a base layer of roller compacted concrete (15 cm).  Apart from the 340.000 m² of pavement, about 23 km of safety barriers are installed and six bridges undergo joint renewals. 

The quality control of the work was performed by external independent bodies : CRIC (Cement Research Centre) for the certification of the concrete mixes and COPRO as an inspection body on site, all this in addition to internal quality plans. Mr. De Koker also highlighted the enormous attention paid to less disturbance measures and communication campaign.

Dominique Valcke, representing the association of  road construction companies STADSBADER  and TRBA, performed a presentation on the phases of the project in detail.  He emphasized the importance of a good worksite organisation in order to ensure a smooth proceeding of the works and to comply with the time restrictions.  He also mentioned the different plants (concrete - asphalt - crushing and screening) and equipment, in particular the brand new slipform paver WIRTGEN SP850 they procured for the realisation of this job.

Luc Rens, Managing Director of EUPAVE, presented “New Developments in CRCP”. He started with the history of CRCP in Belgium, gave the evolution of the design of CRCP and ended with some latest developments and study projects.  The combination of longitudinal bar reinforcement with the use of steel fibres is one of these topics for which an experimental section is provided in the E17 project.

The seminar was closed with a video showing the complete sequence of works from the start of the project up to the present.  After the presentation session, the group departed for the worksite.  The participants were able to see the different stages of the works and could take a look at the finished exposed aggregate concrete surface.  
The event closed with the cocktail at the Maaltebruggekasteel where the participants had the opportunity for a pleasant networking.


16 000 m² fibremix concrete

EUPAVE organised on October 21st, in close cooperation with its Dutch member Cement&BetonCentrum, a technical seminar and excursion on the application of fibremix concrete platforms for heavy traffic at a service station on the A67 near Venlo (NL).

The former border station at the north side of the A67 is, by order of the regional Highway Authorities, being reconstructed to a newly designed public service station. The pavement for the parking platforms for trucks and cars will be executed in fibremix concrete and has a total surface of 16 000 m².
This is the first project in which fibremix concrete is applied on such a large scale.

The representatives of different countries where received by Chris Caestecker, head of the Agency for Roads and Traffic of Flanders, explaining his motivation for building concrete roads in the Flanders region: "a durable, sustainable and low maintenance road contributes to the societal benefits of its users".

Mrs. Anne-Séverine Poupeleer, Project Manager of the worksite and working for the Flemish Agency for Roads and Traffic, gave a description and situation of the worksite. She informed in detail on the phases of the work, the safety measures to be considered, the technical aspects and the quality control on site.

The sustainable benefits of concrete roads were highlighted in a presentation by Luc Rens, Managing Director of EUPAVE. He concluded that performance in each of the three fields of sustainable construction is important: environment, economy, social - societal. He emphasized that no short term gain should compromise the long term behaviour. In the end, choosing a concrete road is choosing for a sustainable solution.

A summary of "Concrete Safety Barriers in the spotlights":

On 9 June '09 EUPAVE organised its own technical seminar focused on concrete barriers and their ability regarding safety and environment.
Nearly 60 participants from 11 countries joined on June 9th in the Brussels' Sheraton Hotel for EUPAVE's technical seminar on concrete safety barriers which focused on "New insights and developments on safety and environment".

David Jones, vice-president of EUPAVE, welcomed the attendees and introduced Mr. Yves Decoene, secretary-general of Road Federation Belgium, who highlighted the need for safe road infrastructure in order to decrease the number of accidents or minimize the impact on the drivers and passengers.  He stated that thanks to research and development a wide variety of materials and equipment is available on the market, yet many places remain unprotected and unsafe.  Finally, he told from his personal experience that a concrete barrier, built in 1977, is still in excellent condition today.

The second speaker, EUPAVE's managing director, Luc Rens, gave a history of the standardization within CEN/TC226/WG1 of road restraint systems.  After a brief review of the existing standards, he summarized the main technical changes in the future revised versions of EN1317-1 and 2.  Amongst the new parts in development, EN1317-8 dealing with the protection of motorcyclist got the most attention.  The final conclusions were that standards constitute an important tool for road safety management; that the main decisions are still to be made by the road authorities and that besides the compliance with EN1317 decision criteria are the need of maintenance; the initial and/or life-cycle cost and environmental performances.

Dr. Bryan Magee from the Concrete Centre (UK) continued with a presentation on sustainability issues.  He gave an overview of Concrete Step Barrier's positive sustainability credentials by assessing its impact against established indicators identified by both industry and key construction clients.

The key construction-related indicators identified by Government and industry were grouped by four themes:
- sustainable production and consumption;
- climate change and energy;
- natural sources and enhancing the environment;
- creating sustainable communities.

The main benefits offered by concrete safety barriers were:
- Material usage and waste sensitive;
- Less embodied CO2 than competing systems;
- Non-polluting in service;
- Fully recyclable;
- Maintenance free over 50 year design life;
- Low traffic congestion and associated emissions;
- Delivers road user and worker safety;
- Contributes to more reliable journeys.


The low embodied CO2 assessed over a maintenance-free design life of 50 years appeared to be a significant benefit.  Both in situ cast and precast barriers profit from this material characteristic.


The final presentation was given by Mr. Richard Sturt from the renowned engineering bureau Ove Arup & Partners Ltd on the new revelations concerning the relationship between acceleration severity index (ASI) and injury of vehicle occupants.  The study he presented consisted of three physical crash tests and 50 computer simulations.  Injuries were measured and compared to limits from volunteer and cadaver tests and plotted against ASI and THIV, being the two significant quantities for impact severity assessment in EN1317.   Results showed that, although ASI did show a correlation with injury risk, the level chosen for the boundary between class B and C barriers in EN1317 does not provide significant discrimination between higher and lower risk of injury.

The figure below shows HIC, what stands for Head Injury Criterion, against accident severity, measured by ASI.  The acceptable level for HIC is set at 325 which is half of the allowed value for head protection in the EuroNCAP (European New Car Assessment Programme) side-impact protocol.  This very conservative approach corresponds to a risk of less than 10% of a moderate injury.  From the results we see that for a ASI up to 1,6 the injuries are very low.  Even with the precautious level of acceptable injury, ASI values up to 1,8 fall within the safe zone.
Similar conclusions were drawn from testing on neck injuries : for crashes with ASI up to 1,7 injuries are unlikely.  While boundaries between ASI classes seem to be arbitrarily chosen, the existing requirement in EN1317 for THIV to be below 33 km/hr represents a reasonable threshold  below which significant injury is unlikely to take place.


As a conclusion, overall safety including containment level, impact severity and need for maintenance should be considered when selecting a type of barrier for a given situation.

The findings of this Britpave study, conducted by Ove Arup & Partners, has been published in the International Journal of Crashworthiness.  A copy can be requested via email (

Characteristics of today's concrete surfaces" - SURF 2008

From 20 to 22 October 2008, the 6th Symposium on Surface Characteristics was held in Portoroz, Slovenia.  This conference is organised by PIARC every four years and allows practitioners and researchers from around the world to meet and discuss technological advances and developments in the field of pavement surface characteristics.

The PIARC Technical Subcommittee on Concrete Roads was represented by Luc Rens (FEBELCEM) who gave a presentation entitled “Characteristics of today's concrete surfaces”, concluding that modern concrete roads, mainly exposed aggregate surfaces with a fine texture, provide excellent and durable solutions for the combination of technical and economic requirements and are applicable for all types of pavements (motorways, trunk roads, secondary road, tunnel pavements, ...).

"Concrete for Roads other than Motorways and Expressways - the Belgian Experience"

On invitation of the Croatian Cement Association, EUPAVE was present on the 2nd Croatian Forum on Concrete Pavements that took place in Zagreb on 28 October 2008. Board Member Luc Rens (FEBELCEM) gave a presentation, entitled "Concrete for roads other than motorways and expressways - the Belgian experience", concluding that concrete is an excellent paving material, not only for the use on heavily trafficked motorways and trunk roads.  But that, in fact, the experiences are even better for low-volume roads.  The extremely long service lifetimes of these pavements, free of any maintenance, certainly justify the somehow higher initial costs.

"Maximising sustainability in road construction" - 4 June 2008

Click to see larger picture

EUPAVE hosted, in cooperation with Febelcem, the Belgian Cement Association, its first worksite visit on the E34 near Antwerp (Belgium), entitled: “Maximising sustainability in road construction”.

Mr. Luc Rens, Consulting Engineer at the department Promotion, Research and Development of FEBELCEM explains the technical aspect of this worksite in detail.

"The technique of double-layered concrete or two-lift paving is applied either to obtain a high-quality top layer, to use lower quality materials in the lower lift, or for both reasons at the same time.

In Europe this technique is commonly applied in Austria where a typical motorway is built with a 25 cm-thick jointed plain concrete pavement consisting of a 20 cm lower layer and a 5 cm upper layer. For the coarse aggregates of the first layer, recycled crushed concrete from former pavements replace the natural stones while the top layer is made of small, polishing-resistant stones with a maximum aggregate size of 8 mm.

Driven by growing environmental awareness and a desire for innovation, the Flemish Road Authorities followed the Austrian example and planned a trial worksite on a 3 km section of the E34 motorway in Zwijndrecht near Antwerp.

Following Belgian tradition, the existing JPCP was replaced with a CRCP.

A first phase was finished in June 2007 by the company WEGEBO, with excellent results for noise, safety and comfort. The second phase started in May 2008 by the company STADSBADER FLAMAND.

By adopting the CRCP long-life pavement concept, the use of reclaimed aggregates and the result of a quieter and smoother surface, different aspects of sustainable construction are combined, to good effect, in this technique."
