Lucobit 1210 A is a mixture of ethylene copolymers and special bitumen. The resulting formulation is a concentrate or "masterbatch".

Lucobit®1210A consists of thermoplastic polyolefins. Addition of Lucobit® to bitumen increases its viscosity and broadens the range of plasticity. Although the minimum value of the Fraass breaking point of Lucobit® is at least as low as for unmodified standard bitumen, the ring and ball softening point increases considerably depending on the proportion of Lucobit®1210A that was added.

Penetration values decline accordingly. Ductility determined according to DIN EN 12591 decreases. However, the values ascertained for the so-called ductility at low temperatures are usually more favorable than those for standard bitumen without addition of Lucobit®1210A.

Product advantages
Compared with other standard binder Lucobit®1210A displays significant advantages in improving resistance to deformation. Rut formation tests 50°C demonstrated that asphalt can bear a two to three-fold load when modifying it with thermoplastics or altering binder viscosity by adding Lucobit.

Applications
Even relatively small amounts of Lucobit®1210A in asphalt mixtures improve:

• resistance to mechanical stress, in particular deformation and wear

• stability / rigidity and reduce the tendency to flow when hot and under load

• low temperature flexibility

• ageing behavior

• s-wearing courses acc. to ZTV-Asphalt StB1

• poured asphalt, also on sloping surfaces (ramps)

• stone mastic asphalt

• special asphalt surfaces e.g. porous asphalt

• thin bituminous wearing courses (hot laying)
