SteelFlow™

        Longer-lasting with better performance and miles more economical.

        Longer-lasting with better performance and miles more economical.

        SteelFlow™ is a sustainable, high-performance, durable asphalt consisting of 95% steel
        slag aggregates combined with a Polymer-Modified Binder (PMB). It can be laid
        ultrathin, allowing budgets to go further, and it also reduces noise pollution and
        increases skid resistance.

        Less is more

        As budgets come under increasing pressure, SteelFlow is welcomed by councils and local authorities that strive to meet the challenge of maintaining safe and serviceable roads within the constraints of tighter budgets.

        Goes the extra mile

        With the durability, strength and skid-resistance associated with SteelPhalt products made from steel slag aggregate, SteelFlow also uses modified bitumen which gives the material greater flexibility and elasticity. SteelFlow can be laid at a depth of just 15mm, resulting in faster installation times, reduced labour and greater surfacing areas for the same volume of product.

        Proven performance

        SteelFlow shows excellent skid resistance figures above the investigation level in SteelPhalt’s grip testing program, especially through the summer months.

        Like many of SteelPhalt’s other products, SteelFlow contains a high percentage of recycled materials at 95%. This gives SteelFlow added appeal to suppliers who wish to meet sustainability criteria.

        Performance statistics

        In a recent case study, one of our customers was looking to cover a section of highway spanning 785 meters. The plan was to use a traditional 14mm dense surface course laid at a depth of 40mm.

        We recommended that they consider using SteelFlow as an alternative solution, laid at 15mm depth.

        By using SteelFlow material, 59% less asphalt would be required to surface the job saving 46% on material costs.

        SteelFlow Benefits

        SteelFlow lays thinner and goes much further than traditional asphalt.

        SteelFlow is a durable, thin, and sustainable surfacing material used in England’s northeast.

        SteelFlow is a highly durable road surfacing product that is laid very thin and has strong sustainability credentials.
        “You’re able to restore all the road surface characteristics without having to plane off old carriageway surfacing.” – David Hepworth, Rotherham MBC.

        Roads refurbished with SteelFlow do not require modification of curb levels or street furniture. Local authorities find that they get more value for their money, especially in terms of square meters covered.

        SteelFlow Laboratory Tests

        SteelFlow shows excellent skid resistance figures above the investigation level when evaluated with SteelPhalt’s grip testing program.

        Specimens have been subjected to a total of 100,000 wheel passes as required by the BBA, equivalent to traffic wear during 5 to 10 years of service life. In each case, SteelFlow met the requirements for the above applications, proving its credentials as a durable and effective road surfacing product.

        Application opportunity

        The Humber Bridge’s surface is a dual carriageway designed to tolerate constant motion and bends of more than three meters in winds of up to 80 miles per hour.



        Recommended product

        Due to the complexity of the requirements, 6 SteelFlow was the ideal material choice for this application.



        Results and benefits

        The material has been monitored as part of our in-house Grip Test programme. Installed in 2017, SteelFlow continues to maintain its SCRIM values.
