Lucobit 1210A

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 as low as for unmodified standard bitumen, the ring and ball softening point increases considerably, depending on the proportion of Lucobit 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 favourable than those for standard bitumen without addition of Lucobit.

Compared with other standard binder Lucobit 1210A displays significant advantages in improving resistance to deformation. Rut formation tests at high temperatures demonstrated that asphalt can bear a two- to three-fold load when modifying it with thermoplastics or altering binder viscosity by adding Lucobit. This does not impair the low-temperature performance of Lucobit 1210A, but rather improves it.

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)
