Lucocell® in stone mastic asphalt (SMA) prevents binder runoff
Regardless of whether it is slow-moving heavy goods traffic, frequent braking and acceleration at bus stops or high temperatures over long periods of time - Lucocell® has proven itself in every respect.
Because of their 3D structure, the cellulose fibers of Lucocell® increase the viscosity of the bitumen. Excess oil is bound in the matrix, preventing separation of the asphalt mixture and binder runoff at high temperatures during storage, transport and installation. At the same time, Lucocell® promotes the formation of a thicker layer of bitumen around each rock particle, thereby protecting the aggregates from air and moisture contact and preventing the aggregates from detaching or breaking. The mass gains elastic resistance.
Lucocell® is easy to handle. During dry mixing, the microgranules are quickly broken down and distributed homogeneously throughout the rock mixture. Lucocell® should be placed in the middle of the mixer about 5-15 seconds before adding the bitumen to ensure even fiber distribution. The standard dosage amount of cellulose fibers is about 3 to 4 kg per ton of asphalt.
