Sustainable asphalt solutions.
High-performance roadmaking products.
SteelPhalt has been developing and manufacturing high-performance asphalt products for roadmaking in the UK industry.
Established in Rotherham in the 1960s, SteelPhalt is ideally located to source slag in a cost-effective manner from the surrounding steel industry - a sustainable way of making asphalt. Additionally, all SteelPhalt products use 95% recycled materials.
With a reputation for first-class products matched by a commitment to innovation and sustainability, SteelPhalt works in partnership with councils, local authorities and contractors to deliver durable roads for a sustainable world.
Steel slag has inherent properties that make it suitable as a surface course for roadmaking.
Some key properties include:
- The exceptional strength and durability of steel slag extends the life of the road and increases the time between road maintenance needs.
- Steel slag achieves and maintains high skid resistance throughout its whole life on the road as a result of its capacity to regenerate its surface roughness over time.
- The use of steel slag avoids the use of quarried materials and avoids landfill of residual slag product.
Through detailed knowledge and experience of working with our roadmaking materials, we are able to offer various products to suit different application types.
SteelPhalt products in action
-
Application opportunity
The A633 Manvers Way was showing signs of fatigue and suffering from high levels of surface noise due to aggregate fretting from the previous HRA surface course.
Recommended product
10mm of SteelPave Eco+ combining locally sourced recycled steel slag aggregate and a bio-binder derived from trees was recommended.
Results and benefits
580 tonnes of material was installed on Manvers Way in 2024 which delivered the durability, noise and carbon reduction, requirements of the local authority.
-
Application opportunity
Residential roads which generally have low traffic volume and lower speed requirements, where typically standard Asphalt Concrete mixtures to EN 13108-1 are specified.
Recommended product
Working with the local authority, SteelDense was chosen as the standard choice for their residential schemes based on durability, performance and environmental benefits.
Results and benefits
SteelDense performs to high standards, providing peace of mind that the material laid was low carbon, long lasting and benefiting the local authorities' budgets and communities.
