Breedon Flex™

The Breedon Flex™ range is produced using an elastomeric polymer-modified binder, giving it greater flexibility than standard asphalt. This enhanced flexibility allows the pavement to accommodate movement and stresses within the underlying layers, rather than transferring them directly to the surface.

In standard asphalt pavements, cracks and defects in lower layers can propagate upwards over time, leading to reflective cracking. Breedon Flex™ is specifically designed to resist this process by flexing with the movement below, helping to prevent cracks from reaching the surface. The result is a more durable pavement with improved resistance to cracking, a longer service life and reduced maintenance requirements.

Yes. The Breedon Flex™ range is well suited to heavily trafficked roads, junctions, roundabouts and other high-stress applications where pavement performance is critical.

Its elastomeric polymer-modified binder enables the asphalt to accommodate small movements within the underlying layers, reducing the risk of cracking and helping the pavement withstand repeated traffic loading. This enhanced flexibility contributes to improved resistance to permanent deformation (rutting) and fatigue cracking, helping to maintain surface integrity for longer.

Yes. The Breedon Flex™ range is suitable for use over both concrete pavements and Cement Bound Granular Material (CGBM), making it an effective solution for pavement strengthening and overlay projects.

Before overlaying, any loose, cracked or deteriorated material should be removed, and all joints repaired and sealed to provide a stable, well-prepared substrate.

Yes. The Breedon Flex™ range can be recycled in the same way as other bitumous materials, enabling it to be reused within future pavement construction and maintenance projects.

No. A Stress Absorbing Membrane Interlayer (SAMI) is not designed to act as a running surface and does not provide significant load-bearing capability. Its primary function is to absorb stresses and reduce the transmission of cracks from the underlying pavement into the asphalt overlay above.

A SAMI is typically installed as a thin interlayer between pavement layers and must be covered with an asphalt overlay before the road can be opened to traffic. The overlay provides the structural strength, durability and skid resistance required for long-term performance.

The minimum overlay thickness required will depend on factors such as local specifications, traffic loading and the specific SAMI product being used. Please contact the team for guidance and recommendations on suitable overlay thicknesses for your project.

Increasing the thickness of an asphalt overlay can improve structural capacity, but it does not necessarily prevent reflective cracking. Cracks, joints and other defects in the underlying pavement can still propagate through a thicker overlay if the stresses causing them are not effectively managed.

Flexible asphalt solutions, such as the Breedon Flex™ range, and Stress Absorbing Membrane Interlayers (SAMI) are specifically designed to accommodate movement and dissipate stresses within the pavement structure. By reducing the transfer of strain from underlying layers to the surface, they help minimise the risk of reflective cracking and improve long-term pavement performance.
