Resins are essential components of clear binders as they enhance the mechanical properties and durability of the mixture while preserving transparency. Once incorporated into clear binders, resins increase stiffness, enabling the asphalt mixture to resist heavy traffic and environmental stresses without deformation. They also improve the binder’s adhesive qualities, ensuring a strong bond with the aggregate —an essential factor for the long-term performance and stability of the pavement.

ValoChem's range of light resins, named ValoRes^TM, offers several advantages:

Binder properties:

• Enhancing the rigidity and mechanical strength of the binder
• Improving adhesion to aggregates
• Maintaining the transparency of the binder, preserving the aesthetic quality of the pavement

Application benefits:

• Increased UV resistance, preventing discolouration and degradation
• Enhanced resistance to weathering and oxidation

Hydrogen sulphide (H2S) is a gas naturally present in many of the world's petroleum crudes. During the refining process, the sulphur naturally present is progressively concentrated, which regularly results in distillation residues loaded with sulphur or related molecules. H2S is therefore present in the gaseous atmosphere above all bitumen, in varying concentrations.

An additional factor in the emission of H2S in the case of bituminous binders is that, because of their viscosity, they are used (produced, transported, modified and applied) at temperatures high enough to induce thermal degradation of the sulphur molecules present.

ValoChem scavengers trap these poisonous emissions inside the bitumen, significantly reducing the HSE risks related to these hazardous particles.
