New needs and open problems on industrial applications of recycling of asphalt pavements

whorkshop1

This workshop will be focused on the different aspects of recycling of asphalt pavements from the point of view of industries and agencies. The main objective is to explore what the industries consider open problems where the research should be focused in the next years. Technical and technological aspects of the different asphalt recycling techniques as well as life cycle assessment and the environmental aspects of these technologies will be addressed. The feedback of the workshop will be collected in a document named “Industry Research Need Statements” that will be published as a Rilem Letter. The workshop is set to be a meeting point for discussion among academia, industries and agencies to have an exchange of idea and a transfer of knowledge and expertise. The assistance to this workshop will be free for EATA2019 Participants. To get access it is necessary to register by sending an email to fmoreno@ugr.es before 24th may 2019. Limited number of places available. Places are allocated accordingly to the order of registration.

Materials and Design for Airport Pavements

worshop2

About the workshop:

New generation aircraft, such as the Boeing 787 and Airbus 350, have tire pressures of up to 1.75 MPa. Since the effects of high tire pressure are localized and concentrated in the surface layers of the pavement structure, it becomes necessary to study the effects of high tire pressures on the asphalt concrete surfaces, and develop asphalt mix design procedures to produce mixes that can withstand these anticipated higher tire pressures. Extensive research is being carried out to develop performance related specifications and high-performance materials that can withstand these high wheel loads and tire pressures. In addition to the materials related research, efforts are being made to develop improved analytical and design tools based on mechanistic principles. This workshop will familiarize participants with the latest research and innovations going on in the field of hot mix asphalt materials and pavement design for airport pavements. For this purpose, the latest FAA (US Federal Aviation Administration) design procedures will be presented, with an emphasis on practical design examples for new flexible pavements (FAARFIELD 1.41 airport pavement design software will be provided, free of charge, to the attendees). Other topics covered in this workshop will include: design life; cumulative damage factors (CDF) and pass/coverage ratio, subgrade and subbase layer characterization for design; etc. The FAARFIELD 1.41 methods of airport overlay design will be also covered if time permits.

The assistance to this workshop will be free for EATA2019 Participants. To get access it is necessary to register by sending an email to fmoreno@ugr.es before 24th may 2019. Limited number of places available. Places are allocated accordingly to the order of registration. Note: It is recommended that workshop participants bring their own laptops so they can install FAARFIELD 1.41 and follow along through the pavement design examples. Ample time will be provided for questions and discussion.

The FAARFIELD 1.41 software can be downloaded free of charge at: http://www.airporttech.tc.faa.gov/Download/Airport-Pavement-Software-Program Advisory Circular 150/5320-6F, “Airport Pavement Design and Evaluation” is available at: http://www.faa.gov/documentLibrary/media/Advisory_Circular/150-5320-6F.pdf
