Asphalt additives represent a number of substances that can be added to the asphalt binder to alter the characteristics of the final blend of asphalt for the construction of the top layer of a road. The type of additive used is depending on several factors, such as the type of road, the underground structure and climate. Additives are selected based on the requirements for the relevant road. For example, the compaction resistance, application difficulty, adhesion and mixing temperature can be influenced through the use of adhesives. In some cases, the additive is already mixed with the asphalt and cannot be bought separately. In other cases the additive is purchased and added to the bitumen mix. Asphalt additives are conventionally made from crude oil fractions but can also be made from biobased materials including vegetable oils, such as soy and canola oil but also lignin. This factsheet provides information on bio-based asphalt additives and how to take these into account in procurement.
