The General Directorate of Roads of the Madrid’s Community (VIA-M CARRETERAS MADRID) is the part of the Madrid’s Regional Government dedicated to promote the development of infrastructures in the region. VIA-M is in charge of managing all the roads in Madrid except some of the main radial-disposal highways managed directly by the Central Government.
Along the last decades, VIA-M is making significant efforts for the enlargement and improvement of the network and roads with the aim of contributing to the better operation of the Community of Madrid’s road infrastructure and improving its safety. In addition, the Community of Madrid is strongly committed to the use of sustainable construction techniques for the development of roads.
The network of roads and highways of the Madrid’s Community accounts for a total of 2.610,628 kilometers, divided into three categories: main network, secondary network and local network. The main network supports the highest demand of road traffic as it includes all the long-distance traffics and connects the main city centers with a total length of 632,132 kilometers.
The use of more environmental friendly containing barriers with improved performance is therefore in line with the VIAS-M CARRETERAS MADRID objectives.
As a Public Body, VIA-M is able to use the contract laws of the public sector to offer biddings for the construction of roads including components more sustainable such as the barriers developed in the present project.
ACCIONA Infrastructure core businesses are the development of major infrastructures projects, covering the whole chain of the projects from engineering to construction and maintenance, building construction and hospital services. Additionally, the company has several support units like the Engineering Department, R&D Technological Center, Metallic Structures Workshop, Machinery Service, Facilities Management, as well as several specialised auxiliary companies.
The company is a leader in Research, Development and Innovation activities, and is ranked among the leading construction companies in the world recognised for its commitment and support of this kind of activities. The R&D Technological Center has more than 120 professionals covering all the science and engineering areas, and develops different research lines related to new materials and processes for the construction sector, many of them supported with funds from local entities and the EU under the FP5, FP6 and FP7, CIP and LIFE+ programs, such as LIFE 2009-WOODRUB – “Utilization of recovered wood and rubber for alternative composite products” or CIP ECOINNOVATION 2008– “RECTYRE- Used tyres valorisation as lightweight filler for embankments”.
Finally, ACCIONA is an active member of some construction platforms both at national and European levels such as the European Construction Technology Platform (ECTP) (on which is part of its High Level and Support Group, leading the Focus Area Cities and Buildings and leading several WGs in other Focus Areas), the Materials Spanish Technological Platform, Materplat, the Energy Efficient Building Association (E2BA) and is member of the AD HOC Advisory Group to the EC on the PPP on Energy Efficient Buildings (EeB).
All the activities carried out by ACCIONA Infraestructuras, are done with careful considerations to environmental, social and economical issues, in accordance with international sustainability regulations and with permanent policies for improving all construction processes for a better and sustainable way of thinking the construction industry.
The European Union Road Federation (ERF) is a non-profit association, which coordinates the views of Europe’s road infrastructure sector and acts as a platform for dialogue, information and research on mobility issues. ERF has a impressive track-record of involvement in European projects related to road safety and smart mobility and is in a unique position to liaise with stakeholders (industry, decision makers) at European level. Furthermore, it is able to provide broad EU wide visibility through its extensive network of contacts with specialised media and members.
The ERF has an active sustainability programme which mainly deals with sustainable road infrastructure and noise mitigation. In has published several Discussion and Position papers which can be found on the compans website.
CIDAUT (Research and Development Center in Transport and Energy), was created in 1993, with the objective of coordinating and channeling the research potential of the University of Valladolid, as well as actively contributing to the needs of companies in the sectors of transport and energy, thus enhancing both their competitiveness and industrial development. CIDAUT foments the use of technology, design and the manufacture of new products, as well as creating advanced programs for improving the industrial process as a whole.
Regarding Safety expertise, CIDAUT is experienced in real world accidents and injury data, biomechanics, dummy development and test methods, integrated safety (preventive safety, active safety and vehicle structural crashworthiness including restraint systems, passive safety), material technologies, road furniture, HMI and ergonomics.
CIDAUT has been involved in quite a number of European Projects in the Integrated Safety scope, as could be VITES, ADVANCE, PRISM, ROBUST, RISER and EVPSN2, from the 5th Framework Programme. In the same field of safety, regarding the 6th Framework Programme, CIDAUT is involved in the following projects: RANKERS, HELISAFE, AIDE, PReVENT, SAFESPOT, APSN, APROSYS, STORHY, TRACE, ETAC, SIM and SAFEINTERIORS. The following ones can be highlighted: ROBUST (Road Barrier Upgrade Of Standards), A 5th Framework “Growth” Project Intended To Develop The Technical Basis For The Next Update Of EN1317 “Road Restraint Systems” performance Srtandard.
RISER (Roadside Infrastructure For Safer European Roads) focused on roadside safety, that is to say, the risks and consequences of vehicles leaving their travel lane and experiencing impact events in the areas bordering the roadway.
CIDAUT leaded the APROSYS SP4 (Advanced PROtection SYStems) focused on motorcyclists advanced protection systems and forgiving road infrastructure behaviour.
The Infrastructure Safety Laboratory Of CIDAUT Is Accredited For The Performance Of Tests According To European Standards UNE-EN 1317 And The Spanish Standard UNE 135900 “Motorcyclist Protection ”.
SIGNUS’ experience in the proposed area is concentrated in two fundamental aspects:
On one hand, the treatment of used tyres through shredding and granulation is a current activity within the set of actions which constitute the proper management of tyres.
SIGNUS has been correctly managing used tyres for more than four years and both shredding and granulation fall within the management activities of SIGNUS. These are carried out through subcontracting specialized companies who are asked to fulfil certain technical specifications according to the target application to which the obtained materials will be directed.
Material collection methods for applications related to this project are currently being developed and are capable of accommodating both the quality and specifications required for the construction of the barriers used in this study.
On the other hand, although the fabrication of concrete is not one of SIGNUS’ activities, three years after its creation in May 2005, SIGNUS started a research project on the incorporation of materials procured from used tyres (granulated, shredded, and steel fibres) in concrete.
Since 20 years have passed since the first studies on rubberized concrete at an international scope were started, SIGNUS has taken advantage of these previous works and has analyzed the documents to develop a new line of work: the substitution of course aggregate for larger sized tyre granulates (12-25 mm), shredded material (size small), and, in some case, steel fibres obtained through the granulation process.
Even though this study has finished as such, there is still much work to be done, in order to apply it different applications. The results from this project can help establish new paths for research in order to obtain a specific material for the fabrication of security barriers.
