Asphalt

In recent years a lot of effort has gone in to developing novel techniques to reduce energy consumption during production. Warm mix asphalt is an excellent example of how the asphalt industry has found better technical solutions, however the best way of maximizing energy saving and carbon reduction would be to make cold asphalt. In 2012 Swedish road authority started an improve the understanding of cold mix design, production of a strong relationship was found between surface area, chemical composition of stone aggregate and breaking rate of emulsions.
