Research & Development
SteelPhalt’s onsite laboratory facilitates compliance with our quality protocols, ensuring that we meet our high standards of quality products and service.
Our extensive knowledge in research and development of steel slag asphalts is utilised around the world within Harsco. We have worked very closely with our suppliers to design asphalts for specific applications which can be seen within our products range.
SteelPhalt have also commissioned world renowned authorities to look at specific aspects of steel slag such as Sheffield Hallam University, Ulster University, and Transport Research Laboratory.
We have worked with TRL (Transport Research Laboratory) over the last 3 years to produce and publish reports on the durability, and skid performance of steel slag asphalts. From our own Grip Testing programme we could see that Steel Slag delivered better skid resistance than obtained from laboratory PSV testing. From this we commissioned TRL to assess the skid resistance as well as comment on the durability of the products, in addition polishing resistance was conducted in the laboratory using the friction after polishing test to establish if this was a more representative test for steel slag.
The reports can be downloaded free from TRL web site www.trl.co.uk, the report numbers are
- PPR737 - In Service Performance of SteelPhalt Products
- PPR773 - In Service Performance of SteelPhalt Products (2015)
The third report will be available later in 2016
