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

Lucobit® 1210AC consists of thermoplastic polyolefins. Addition of Lucobit to bitumen increases its viscosity and broadens the range of plasticity. Depending on the proportion of Lucobit 1210AC that was added the minimum value of the Fraass breaking point of 1210AC modified bitumen decreases and the ring and ball softening point increases.

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 more favourable than those for standard bitumen without addition of Lucobit.
Product advantages
Compared with other standard binder Lucobit 1210AC displays significant advantages in improving resistance to deformation. Rut formation tests at high temperatures demonstrated that asphalt can bear a two- to threefold load when modifying it with thermoplastics or altering binder viscosity by adding Lucobit. The low temperature properties of Lucobit 1210AC modified asphalt also improve significantly.

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 behaviour

Examples for application:

• s-wearing courses to ZTV-Asphalt - StB

• poured asphalt, also on sloping surfaces (ramps)

• stone mastic asphalt

• special asphalt surfaces, e.g. porous asphalt

• thin bituminous wearing courses (hot laying)
