Evaluation of usage of Swedish waste foundry sand in manufacturing of asphalt mixtures

Reduction of the environmental impact of road construction can be achieved by replacing the virgin aggregates used in construction by waste materials. The current project deals with sustainable manufacturing of asphalt mixtures incorporating local by-product, namely Swedish waste foundry sand (SWFS) to substitute part of the virgin aggregate is asphalt. This will be achieved by selecting two suitable local types of Swedish waste foundry sand (SWFS) that goes well with the Swedish environmental and technical regulations. The SWFS will be incorporated at different percentages in asphalt mixtures and the resulted asphalt mixtures will be tested at lab scales. The developed asphalt mixtures will be evaluated based on durability, stability and sustainability performances on the light of the current Swedish Transport Administration requirements. To reach this goal, close cooperation between SWFS introducers, research institute and final by-product (asphalt) manufacturers is considered.
