Lucolast® 7010AC
Product properties
Addition of Lucolast® 7010AC to bitumen increases the range its viscosity and broadens the range of plasticity. Depending on the proportion of Lucolast® 7010AC that was added the minimum value of the Fraass breaking point of Lucolast® 7010AC modified bitumen decreases and the ring and ball softening point increases.
Penetration values decline accordingly. Ductility determined according to DIN EN 12591 decreas-es, however, the values ascertained for the so-called ductility at low temperatures are more favourable than those for standard bitumen with-out addition of Lucobit 1710AC.
Product advantages
Compared with other standard binder Lucolast® 7010AC displays significant advantages in improving resistance to deformation. Rut formation test 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 Lucolast® 7010AC. This does not impair the low-temperature performance of Lucolast® 7010AC, but rather improves it.
Applications
Even relatively small amounts of PmB based on Lucolast® 7010AC 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)
