1st International Workshop on the Use of Biomaterials in Pavements


The interest in the use of alternative materials for road pavements has increasingly grown in the last decades including the utilisation of recycled and bio materials. Biomaterials are materials coming from renewable sources which can have different roles in new asphalt mixtures.

The 1st International Workshop on the Use of Biomaterials in Pavements is taking place in Granada in on the 13th and 14th June 2022. The aim of the workshop is to share our experience in the use of this type of materials to advance scientific knowledge, encourage transfer and application of this knowledge world-wide. The final purpose is to start creating a scientific community of experts and interested people on this recently emerged topic.

The workshop welcomes every type of professional interested in the field of using biomaterials in road pavements: researchers, industry, policy makers, students, academics, road agencies, etc.

The workshop covers the following topics for biobinders, bioadditives and bio asphalt mixtures:

  • Available resources
  • Biomass transformation processes
  • Ageing
  • Durability with aggregates
  • Recycling 
  • Life Cycle Analysis




Like all other large industries, road construction sector has to move towards more sustainable manufacturing technologies. One possible solution is to replace conventional bitumen by bio sourced binders or/and bio-additives. More and more studies are published every day, all over the world. Various experiments have already been undertaken: in lab, full-sclae, on field, using local biomass, employing different ways and processes to adapt these biomaterials to road material specifications.

Now is the time to share experiments to compare solutions, understand the limitations and hopes arising from this new way of thinking about road construction technology. We propose to run up a collaborative platform dedicated to bio materials in road construction. The 1st International Workshop on the Use of Biomaterials in Pavements will be the opportunity for that. We aim at creating during the workshop, a fruitful environment to discuss and confront approaches, with the aim to finally define the roadmap for biomaterial integration in road materials.

As outcome of the workshop, a white paper or roadmap will be published, putting together and summarising all the contributions, discussions and conclusions obtained during the development of the workshop, aiming at being the reference document for the use of biomaterials in pavements for the next decades. Certificates of attendance will be provided to participants.

If you are working or are interest on this topic, you cannot miss the opportunity to be part of this new community!

The workshop will be held on the 13th and 14th June 2022.
