“Best Practices in Concrete Paving”

The EUPAVE workshop on “Best Practices in Concrete Paving” took place on 26 May 2015 in Brussels.

The workshop gathered 40 experts active in the concrete paving sector such as contractors, designers, road construction engineers and academics, where the participants had the unique opportunity to exchange on best practices, as well as to discuss solutions to challenges and difficulties experienced in application.

Mr. Stéphane Nicoud, EUPAVE President

Mr. Stéphane Nicoud, EUPAVE President, opened the workshop by presenting EUPAVE and highlighted the new affiliation category “Partner”. EUPAVE has recently stepped up its efforts in its main activity areas in sharing of best practices and communicating the benefits of concrete pavements.

Mr. Rory Keogh, Best Practices Working Group (WG) Leader, presented the activities of the WG. A priority for the WG, as determined by EUPAVE members, was to look at all aspects of Surface texture and Evenness, hence the subject for this workshop.

Mr. Keogh explained that the objectives of the Workshop were to involve EUPAVE's new “partners” in giving answers to both design and construction issues in order to move in the same direction with regards to quality and sustainability. Since smooth roads :
o Are safer
o Last longer and stay smooth longer
o Save money in maintenance
o Save money in fuel consumption
o Save money in vehicle operating costs
we cannot afford bad practices.

Moreover, EUPAVE has taken the commitment of editing a new brochure based upon an existing (1991) World Road Association (PIARC) Technical Report “Achieving and maintaining the evenness of concrete pavements” and the fruitful discussion serves as input from the industry to the drafting of this document.

Mr. Margo Briessinck, PIARC, gave an introductory presentation and clarified that PIARC prefers the positive term “evenness” among the frequently used terms “evenness”, “smoothness”, or the converse, “roughness”. In addition, Mr. Briessinck presented the indicators of evenness and different methods used to measure those indicators in different countries.

Mr. Luc Rens, Managing Director of EUPAVE, started the discussion on achieving and maintaining the evenness of concrete pavements by presenting parameters affecting smoothness. Mr. Rens mentioned the control and maintenance of evenness during the construction as well as corrective treatments such as grinding and grooving and milling, different case specific constraints depending on the base type and design and construction methods (track paths; stringlines or stringless systems; speed of paver; single layer or double layer; jointed or continuously reinforced concrete pavements), and factors affecting evolution of evenness during service life.

The participants contributed to the debate by expressing their experience in application and concerns and constraints during construction. The debate showed that similar cases confronted during construction of concrete pavements were solved by different approaches.

During the final session, Mr. Keogh brought up the discussion on construction skills, training and licencing for machine operators. The high turnover frequency of the personnel was mentioned as the key barrier by the participants.   

Being linked to the important aspects such as comfort, traffic noise, fuel consumption and CO2 emissions and durability, this successful workshop on achieving and maintaining the evenness of concrete pavements kicked off the series of best practices workshops. The participants suggested “Tunnel pavements”, “Overlays”, “Industrial flooring” and “Joint layout for JPCP” as priority topics to be dealt with in similar workshops in the near future.
