Stone mastic asphalt comprising recycled fibre
A stone mastic asphalt wherein recycled absorbent hygiene product fibres are used as the fibre in the stone mastic asphalt. Methods of producing a stone mastic asphalt comprising recycled absorbent hygiene product fibres are also disclosed. The fibres may comprise polyethylene, polypropylene, cellulose, and/or elastomeric polymers. Preferably the fibres are present at 0.01% to 2 % by mass of the mixture, most preferably at between 0.1% and 0.5% by mass of the mixture. Coarse aggregate is present in the mixture at 50-80% by mass and fine aggregate is present at 15-45% by mass of the total mixture. Filler is present at 4-12% by mass of the mixture and the binder is 5-7% by mass. In an embodiment, the aggregate, filler and fibre components are mixed in a first step and then the binder is added, and the mix heated to between 100-200°C. Alternatively, all components may be mixed simultaneously.
