Adhesion promoters (also known as antistripping agents) are used to strengthen the bond between the bitumen binder and aggregates. Strong adhesion is essential to prevent moisture-related damage that can cause stripping or separation of the binder from the aggregates, ultimately weakening the pavement and reducing its lifespan. These promoters are especially important in environments exposed to rain, snow, or temperature fluctuations.

Valochem’s range of adhesion promoters offers enhanced adhesion properties over a broader spectrum of aggregates and improved ageing resistance compared to the standard amine chemistry. When incorporated into asphalt mixes, these adhesion promoters alter the bitumen/aggregates affinity, forming a stronger bond that keeps the asphalt mixture cohesive, even under moisture or environmental stress. By preventing stripping, they help preserve the pavement’s structural integrity, resulting in longer-lasting and more durable road surfaces.

When added to asphalt mixes, adhesion promoters chemically modify the bitumen to improve its affinity for aggregates. This stronger bond ensures that the asphalt mixture remains cohesive, even in the presence of water or other environmental stresses. By preventing stripping, adhesion promoters help maintain the structural integrity of the pavement, leading to longer-lasting and more durable road surfaces.

Crosslinking is a process that forms a three-dimensional polymer network by chemical reaction into PmB. Hence, storage stability of modified bitumen is highly improved. When only a linear SBS was usable, it becomes possible to use a radial SBS.

Our crosslinkers are using sulphur as crosslinker agent. They are designed to control the emission of the sulphur species generated during the crosslinking, to ensure the safety of the operators, and to limit the risks during bitumen modification.
