Summary of UNIVERSITA’ DI PISA – DICI activities
In this first phase of the project, the activities of the Department of Civil and Industrial Engineering at the University of Pisa consisted of a preliminary analysis and review of the state of the art of existing techniques for the detection of the highest amounts of recycled materials (recycled asphalt pavements and crumb rubber from End-of-Life tyres) and specific additives and technologies used to reduce the temperatures of set-up and realization. On the basis of this and on the results obtained from a preliminary study of the constituent materials, the design mix was conducted in laboratory to develop technical specifications for the new types of low noise emission mixtures containing recycled rubber (CRM) and produced with the "warm" technology, forecast in the first stretch campaign.
In order to assess the degree of environmental sustainability of the proposed experimental pavements, a thorough Life Cycle Assessment (LCA) study was conducted on all possible combinations of wear layers containing recycled asphalt and recycled rubber, produced with warm technology; this LCA was compared with a gap layer wrapped at hot temperature, as a reference; this procedure of analysis made possible to evaluate the environmental burdens associated with each type of mixture in terms of material, energy consumption and emissions, providing results that fully satisfy the "green” objectives expected.
At the same time, on the stretched sections of the SRT 439 Sarzanese-Valdera in Massarosa (LU), where the first experimental realization was planned in the fall of 2017, were performed measurement of lift with a Falling Weight Deflectometer (FWD) equipment and carried out a continuous evaluation of pavement thickness with Ground Penetrating Radar (GPR) equipment.
The processing of the acquired data made possible to determine the criterions of the constituent layers of the package and therefore to assess the remaining useful life of the existing pavement and the increase in expected life as a result of the realizations of the new layers.
Summary of ARPAT activities
ARPAT activities focuses on monitoring implementation sites. Actually the ante-operam monitoring at first implementation site (Comune di Massarosa (LU)) is completed and analysis are ongoing. To permorm these actions, ARPAT contributed to the selection of candidates sites with Regione Toscana in order to identify suitable places for laying the new pavements. Sites of regional action plans have been filtered and visited according technical parameters and final decision has been taken by Regione Toscana.
Then a selection of acoustical methods and indicators have been carried out to define methodologies for ante and post operam monitoring campaigns. ARPAT has also contributed in methods for psychoacoustical measurements such that noise and psychoacoustical parameters have been acquired in agreed locations.
CPX, method has been applied along the whole stretch of road that will be layed with the new pavements. Noise from continuous noise monitoring stations was acquired in 6 locations rapresentative of each stretch of new surfaces.
In combination with standard by law noise levels (Italian and European) several additional noise indicators will be elaborated from continuous monitoring.
ARPAT is also developping a new methodology in order to acquire SPB-like data in urban areas without manned measurements. Urban pass by methodology has been tested in two location to select indicators and to define measurement protocol. Data analysis is actually ongoing. Data has been also acquired according a preliminary protocol in 4 of 6 ante operam locations in order to test indicators.
In the next 3 months, analysis of urban pass by will be finalized and method is going to be validated before the end of 2017. Ante-operam acoustic indicators will be reported in september.
ARPAT has also acquired together with CNR population data from municipality in order to evaluate people living along the road stretches that will benefit from mitigation. Finally ARPAT has been involved in several dissemination activities. Two scientific papers have been published (ICSV and AIA conferences). Two events at fairs and two workshops have been attended to disseminate projects. Arpat newsletters reported news on nereide in November and March issues.
Summary of ECOPNEUS activities
Ecopneus coordinate the design and implementation of communication materials to support project activities. The LIFE Nereide website will serve throughout the duration of the project as a constant point of reference for partners and potential stakeholders, as well as an up-to-date source of information about project objectives, initiatives and progress. The site contains all the key information about the project, planned actions, expected goals, partners and their roles.
Have been realized also a Papers Notice Board, which contain the main informations, both in english and in Italian, about the Nereide project: summary of objectives and results attended, Nereide Logo and Logos of the partners. The paper notice boards have been printed and sent to all the partners and placed in public places. Also, a roll-up has been created with a summary of the poster’s information: it will be used during conference, workshop and other public events, according to the foreseen dissemination activities.
Other communication tools are been planned and realized, to maximize the dissemination of informations to specific public: a tri-fold leaflet, a small folder for public events and 1-to-1 meeting, a PowerPoint standard presentation and a press release format.
Thanks to dedicated press activities carried out by Ecopneus on a selection of journalist interested to the topic and to other dissemination activities carried out by the other partners, over 100 articles has been published, also on the major national newspaper.
During the Asphaltica Fair, the most important national event on asphalts and roads that was held the 22-25 February in the city of Verona, a demonstration workshop was organized by Ecopneus on the modified asphalt. According to the NEREIDE Project partners, one of the focus during the workshop was the NEREIDE project. Massimo Losa, Professor of the Department of Civil and Industrial Engineering (DICI) at the University of Pisa (that is the Project coordinator) and Gaetano Licitra, member of ARPAT, the regional environmental protection agency of Tuscany region, have outlined the objectives and the expected results of the project to the participants at the workshop.
Over 70 people (including representatives of the Public Administration, decision makers, academics and companies of the sector) attended at the event. About 1,500 persons have been invited via e-mail and a selection of about 600 have been called by phone to point out the event. A NEREIDE panel was also strategically placed in an area of the Ecopneus’ stand at Asphaltica, that allows visitors to sit and read about the project objectives and activities forecasted.
A further opportunity for networking was held in July during a conference dedicated to the LIFE ReFibre project (which aims to obtain extremely durable pavements thanks to the use of recycled materials), during which a session was dedicated to the Nereide project.
Other actions will be implemented to support the advancements of project activities.
