Bitumen Modification with Lucolast® 7010:
Longer durability, fewer cracks, better roads

The properties of bitumen, which is used as a standard binder in road asphalt, are highly dependent on temperature. Therefore, the resistance of asphaltene at higher temperatures is not without problems. One characteristic value is the plasticity range of the binder, which is defined as the difference between the softening point RuK (ring and ball) and the breaking point according to Fraaß. These values allow a statement to be made about the temperature behavior and suitability for use of the intended asphalt.

Modifying bitumen with plastics, e.g. Lucolast® 7010, is a proven approach to improving the properties. In particular, it aims to increase the plasticity range, i.e. to increase the strength at higher temperatures, and, if possible, to also improve the plasticity at low temperatures. Important properties such as adhesion or viscosity must not be impaired at the respective processing temperature.

The modified binders must of course also withstand the usual processing temperatures of asphalt processing (up to 180°C for rolled asphalt and 240°C for mastic asphalt) as well as the long-term exposure of the asphalt to UV radiation.

Lucolast® 7010: Higher temperature resistance and flexibility

Lucolast® 7010 is a high-quality plastic granulate made from ethylene and butyl acrylate, which specifically improves the temperature resistance and cold flexibility of the bitumen used and thus significantly increases the plasticity range in both directions. By adding Lucolast® 7010 to the bitumen, road surfaces become more durable, flexible and resistant to aging processes.

Lucolast® 7010 protects the bitumen from harmful UV radiation and is stabilized against aging. This means that the binder retains its quality and performance over a longer period of time and temperature range, reducing maintenance costs and thus reducing overall costs.

Overall, Lucolast® 7010 offers an environmentally friendly and economical solution for expanding the plasticity range of the bitumen used. The usual dosage is up to 5% in the binder, depending on the application. Mixing at 165 - 195°C in commercially available stirring units takes 1 - 3 hours; when using high-shear mixers, the dosage must be increased slightly due to the inevitable mechanical degradation of the polymer.
