Pure bitumen: bitumen, also called anhydrous binder or hydrocarbon binder, is used in road materials, sealants, and industrial applications. Its viscoelastic properties contribute to the mechanical behaviour of pavement structure. It is impermeable to water and ensures waterproofing. It has great adhesive capacity and is very easy to recycle, making it an essential construction material. In efforts to overcome weather constraints, traffic-related change, and new application techniques, the research centre has developed a new range of anhydrous binders.
Modified binders: these binders are modified by introducing polymer and/or other types of additives. New additives combined with specific production techniques result in a diversified range of binders that can meet various use requirements. Production techniques in plants vary according to the type of bitumen, the nature of the polymer (plastomer, elastomer) and/or other additives and target properties. Eurovia’s range of modified binders has several specific uses, including coating or spreading techniques.
To ensure the performance of our binders, we conduct multiple standardized European and American tests, including penetrability and ring-and-ball tests, which measure the temperature at which a steel ball penetrates a layer of bitumen. We possess state-of-the-art equipment such as a dynamic rheometer, a differential scanning calorimetry device, and optical microscope for image analysis.
Recent innovations: Sequoia® is a plant-based binder produced from agricultural resources. It replaces standard bitumen in decorative and qualitative applications. It can be used to enhance safety, visual appeal, and user comfort. Eurovia has also pioneered a new anti-kerosene binder, which has led to the Kerovia® range of mixes.
