Themes

Contributions are invited from all people working with roads and infrastructure, e.g. road, rail and airport administrations, infrastructure engineers and highway concessionaires, contractors, research institutes, consulting engineers, financial specialists, equipment manufacturers. Our target audience is road users, road authorities, research institutes, consultancies, road financing authorities, bituminous binder producers, asphalt producers and contractors.

Keynote speakers will be invited to provide their view for each of our strategic themes. The overarching theme is “Asphalt 4.0 for future mobility”.

HEALTH & SAFETY

Ensuring the health & safety of the workforce and the public is a critical aspect of all activities that we undertake. Our industry
has been working over many years to improve working conditions and manage the risks associated with the handling and
application of our products. Papers are invited on topics covering the following areas and other related subjects;

  • Work zone safety
  • Exposure monitoring & reduction
  • Noise reduction
  • Air quality
  • Water qualitySkid-resistance
  • Visibility
SUSTAINABILITY & ENVIRONMENT

Today the importance of the impact of our activities on the environment cannot be ignored, increased focus on green public procurement and sustainable development is increasing. Asphalt is one of the most reused / recycled products. Although recycling has been used for many decades still new techniques are being developed and higher percentages of reuse / recycling become common practice. Papers are invited on topics covering the following areas and other related subjects;

  • New reuse / recycling techniques
  • Use of rejuvenators
  • Sustainable development
  • Life Cycle Inventory
  • Carbon footprint
  • Energy efficient pavements / Rolling resistance
FUTURE ROADS AND MOBILITY

The development of future automated and guided vehicles may present new challenges for pavement engineers, these vehicles might need new pavement technologies. In addition to the road network being used for transportation of people, it is increasingly also a conduit for other technologies. Intelligent infrastructure management enables faster communication and reduced delays. Papers are invited on topics covering the following areas and other related subjects;

  • IT and sensors in infrastructure
  • Cleaning air by using absorptive pavement materials
  • Heated/cooled roads
  • Dual-purpose pavements (cool pavement technology, energy generation, etc.)
  • Intelligent roads
  • Roads as a means of connectivity
BINDER PERFORMANCE AND TESTING

Bitumen is a complex product and therefore new test methods are developed to describe the behaviour of bitumen. Papers are invited on topics covering the following areas and other related subjects;

  • New test methods
  • Performance based standards/regulations
  • Evaluation of test methods
  • Predictive performance models
  • Bitumen modification
  • Bitumen ageing
ASPHALT MIXTURE PERFORMANCE AND TESTING

A sustainable pavement must be durable and its performance should meet the requirements over a long period. The required performance for the present and future can be achieved by using an adequate design of the pavement and mixtures by using suitable binders and where needed additives. Papers are invited on topics covering the following areas and other related subjects;

  • New mixtures
  • New test methods
  • Evaluation of test methods
  • Performance based contracts and experience with these contracts
  • Performance based standards/regulations
  • Construction Products Regulation
  • Additives
  • Predictive performance models
  • Durability
ASPHALT PRODUCTION, PAVING AND COMPACTION TECHNIQUES

New technologies are being developed and used in the production, transport, paving and compaction of asphalt mixtures. New techniques are available for continuous quality control in various stages of the process. Papers are invited on topics covering the following areas and other related subjects;

  • Process control
  • Process optimisation tools
  • Intelligent paving and compaction
  • Continuous Quality Control systems
  • Autonomous equipment / autonomous asphalt rollers
  • Quality management systems
  • Efficient production techniques
WARM MIX ASPHALT / LOW TEMPERATURE ASPHALT

A practical way of reducing the energy used during the production of asphalt is the use of low-temperature asphalt or warmmix asphalt. In addition to energy reduction, low production and paving temperatures also reduce emissions and occupational exposure in the workplace. Papers are invited on topics covering the following areas and other related subjects;

  • Temperature reduction technologies
  • Ways to stimulate these techniques
  • Performance
SOCIAL ECONOMY

Financing road infrastructure continues to be one of the major challenges we face. With limited resources available it is important for the society that money is efficiently used. Papers are invited on topics covering the following areas and other related subjects;

  • Long-life pavements
  • Life-cycle costing
  • Project financing
  • Public-Private Partnership (PPP), Design, Build, Operate contracts, etc.
  • Functional contracting
  • Long-term contracts
  • Communication and social awareness
MAINTENANCE AND REHABILITATION

In many countries the focus has shifted from construction of new highway infrastructure to maintaining the existing road network. Increased utilisation of the network means that opportunities exist for novel maintenance techniques and faster intervention. With limited resources available it is important that maintenance intervention is properly planned and carried out in the effective way. Papers are invited on topics covering the following areas and other related subjects;

  • Pavement Management systems
  • Asset management
  • Surface treatments
  • Innovative maintenance techniques
  • Performance based maintenance
  • Fast application technology
  • Road condition monitoring
CASE STUDIES & NON-HIGHWAY APPLICATIONS; SUCCESS AND FAILURE FROM REAL PRACTICE

This category represents a new approach and is focused on practical experience in both highway and non-highway applications.
Papers are invited on projects including ports, railway tracks, aircraft runways and other applications.
The truth is always on the road; and good laboratory results don’t always translate to practical outcomes for a variety of reasons. Learning from good and best-practice represents a valuable treasure trove of knowledge. Papers are invited that report on new ideas that have been tested at industrial-scale production and/or a real construction site and have proven themselves in practice for a reasonable time. Papers are invited on both success stories and failures, in particular where the cause of the failure is well-understood. At best, they contain an approach that has already been reported at the development stage at one of the previous congresses.
