Repsol Advance - EFIMUL for Open-graded cold mixtures

Repsol has developed the medium-breaking bituminous emulsion C67BF3 MBA EFIMUL, which is formulated ad-hoc for open-graded mixtures that can be stored and handled at ambient temperature. It is specially designed to leverage the versatility and mobility offered by bitumen slurry manufacturing and spreading machinery.

Properties and applications

In some cases, due to the characteristics of the construction project, it is impossible to install cold-mix surface courses plants, either because there are no adequate locations or because of problems achieving the required administrative and/or industrial licenses. The Repsol emulsion ADVANCE C67BF3 MBA EFIMUL can be used to manufacture open-graded cold mixtures in a bitumen slurry manufacturing unit, providing the following properties: 

• Stability with regard to the aggregate studied
• Stability in storage
• Optimal adhesion conditions to the aggregate/binder
• Suitable viscosity for the aggregate used and the components of the manufacturing equipment
• Versatility and easy handling in manufacturing and supply.
