In this thesis an extensive background study on the use of bio-oil modified binder, used in surface dressings in Iceland, was carried out. Surface dressings, or chip seals, are paved by first spraying out binder and then distributing aggregates over the surface before compaction. The bio-oil, most notably fish oil ethyl ester or rape seed oil, is included in a binder mixture to lower its viscosity, enabling the binder to be sprayed out at a lower temperature than unmodified bitumen.
