Frequently Asked Questions

Is steel slag asphalt as good as natural aggregate asphalt?

Yes it is. In fact, in many respects the combined benefits of steel slag aggregate make SteelPhalt products superior to natural aggregate asphalt – but with the added environmental benefits of simultaneously reducing both quarrying and landfill.

Does steel slag expand?

Steel slag is a by-product of the manufacture of steel and does contain small quantities of un-combined (free) lime, which will expand in the presence of moisture. However, if slag is controlled and processed correctly, this phenomenon can be reduced and does not adversely affect the asphalt.

Does SteelPhalt produce the same types of asphalt as other national suppliers?

Yes, SteelPhalt supplies asphalt, compliant with national/European standards, but we also produce a range of proprietary surfacing materials with specific properties to match the demanding requirements of a wide variety of applications/situations.
