SteelPave™ is a high-performance stone mastic asphalt (SMA) designed to meet the demands of modern traffic conditions.
In environments where traffic is continuous and distributed across the surface, asphalt must maintain structural integrity under sustained loading. SteelPave is developed for these conditions, providing durability, skid resistance, and consistent performance across high-traffic road networks.
Like many other SteelPhalt products, SteelPave consists of up to 95% recycled materials. This supports sustainability objectives while maintaining the performance required for demanding road applications.
SteelPave is designed to perform under continuous traffic loading, where wear occurs gradually across the surface rather than in concentrated points. This makes it particularly suited to higher-speed environments where consistent surface performance is essential.
The following SteelPave products are approved by the UK Highway Authority Product Approval Scheme (HAPAS):
As a high-performance asphalt surfacing product, SteelPave is designed to meet the requirements of highway authorities and major infrastructure projects.
These approvals confirm that the material has been tested and validated for use in applications where compliance with established performance standards is required.
SteelPave is the ideal SMA slag asphalt for various applications, including:
These environments require surfaces that can withstand continuous traffic, including heavy goods vehicles, while maintaining skid resistance and surface stability.
Traffic loading in these applications is typically distributed across the surface, requiring materials that maintain performance over time without excessive rutting or degradation.
SteelPave incorporates steel slag aggregate, supporting the reuse of industrial by-products and reducing reliance on virgin materials.
This contributes to more efficient material use while maintaining the performance required for modern infrastructure.
Specimens have been subjected to a total of 100,000 wheel passes. SteelPave 14 and SteelPave 10 products have been approved by the UK Highway Authority Product Approval Scheme (HAPAS).
SteelPave has been used across road networks where durability, safety, and long-term performance are critical.
Typical outcomes include:
This makes SteelPave particularly suitable for road networks where maintenance access is limited and long-term performance is a priority.
SteelPave is commonly specified based on:
SteelPave is typically selected for higher-speed road environments where performance is required across the full surface area. In contrast, other materials may be more appropriate in lower-speed environments where stress is concentrated in specific locations.
The A633 Manvers Way is a major single-carriageway linking Rotherham to Barnsley that carries heavy goods vehicles commuting to the M1.
10mm SteelPave Eco+ was offered as the solution due to its durability, resistance to deformation, skid resistance and spray reduction properties.
The material is durable, so the local authority will save on future budgets. The total carbon reduced was 33.9 kg CO2e per tonne of asphalt.
The A631, located in Rotherham, South Yorkshire, is a single-carriageway that carries a high volume of traffic that leads to and from the M18.
10mm SteelPave was offered as the solution due to its durability, resistance to deformation, skid resistance and spray reduction properties.
