Quality control of cement and concrete in road surfaces
Throughout the 50 states, the laboratories at the State Department of Transportation (DOT) endeavor to understand chemical changes causing road failure or damage (such as aging or deicing salts), the quality of construction materials such as cement, steel and asphalt, and the structural integrity of existing structures.
XRF analysis of pavement materials
One of the key tools in these labs arsenal is X-ray Fluorescence (XRF). XRF is an ideal technique for non-destructive elemental analysis of the following material at DOTs:
- Cement and concrete
- Iron, steel, and aluminum
- Tars, Pitches, and Oils
- Coatings and Paints
Thermo Scientific portfolio of XRF products is able to meet your laboratory needs, with instruments suited for smaller lab spaces with low sample volumes to central labs supporting the entire states analytical needs.
