Lucocell®: The stabilizer for stone mastic asphalt

The production of stone mastic asphalt (SMA) requires an increased proportion of bitumen compared to other asphalts. Due to the high binder content, the stone mastic asphalt tends to experience so-called binder run-off when mixed and laid, a separation of low-molecular oily components from the matrix.

Lucocell® are microfibers made from cellulose that were specifically developed to modify stone mastic asphalt.

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.

Lucocell® fits all road asphalts in which SMA is used, such as

  • New construction of motorways and country roads
  • City streets and sidewalks
  • Parking spaces and garages
  • General road construction and rehabilitation
  • Airports
  • Industrial areas and logistics centers

Please note that the application of Lucocell® depends on the specific requirements of the project, local conditions and manufacturer recommendations
