Key Features Fibres

The production of stone mastic asphalt requires the mixing of copious amounts of bitumen compared to other asphalt compositions. The SMA mixture is very rich in aggregates. However, due to the high binder content, a form of separation - also known as binder run-off - is to be avoided. Here, the product Lucocell® is the right choice. Dosing 0,3 % - 0,4 % Lucocell® to the SMA mixture prevents binder run-off while SMA homogeneity is maintained.
