Load spectrum for utility trenches in the footway (2003)
Journal Article
Reid, A., Fairfield, C. A., & Sibbald, A. (2003). Load spectrum for utility trenches in the footway. Proceedings of the ICE - Municipal Engineer, 156(1), 57-66. https://doi.org/10.1680/muen.156.1.57.37647

Local authorities are concerned about the adoption of cable television networks after they reach two years of age. Concerns have been raised about the shallow burial depth (250 mm to the crown for ducts in footways), the longevity of the reinstatemen...

Continuous surface wave and impact methods of measuring the stiffness and density of railway ballast (2002)
Journal Article
Fairfield, C., & Zagyapan, M. (2002). Continuous surface wave and impact methods of measuring the stiffness and density of railway ballast. NDT and E International, 35(2), 75-81. https://doi.org/10.1016/s0963-8695%2801%2900034-2

Continuous surface wave and transient impact excitation tests were performed on strips of ballast to monitor their compaction. The ballast's shear wave velocity, hence the ratio of its shear modulus and density, increased with depth. Two types of tra...

Risk sensitivity applied to arch bridge assessments: an introduction. (2001)
Journal Article
Ng, K., Fairfield, C. A., & Sibbald, A. (2001). Risk sensitivity applied to arch bridge assessments: an introduction. The structural engineer : journal of the Institution of Structural Engineers, 79, 31-37

There are approximately 75,000 masonry arch bridges in the UK, most of which were built between 1700 and 1900 and are now carrying traffic loads far beyond those envisaged by the original designers and builders. A question has to be asked as to wheth... Read More about Risk sensitivity applied to arch bridge assessments: an introduction..
