The engineering properties (e.g. strength,deformability, permeability) of the soils andcompacted fills that form the foundations forour infrastructure are known to change whenstresses are applied. These stresses can takethe form of increased traffic loading on aroad or rail line, or can be produced by thematerial shrinking and swelling as thematerial dries out in summer and becomessaturated in winter months. Whilst thesedrivers of deterioration are known [1,2] themechanisms through which the deteriorationoccurs is less well understood. To predicthow our infrastructure may deteriorate in thefuture it is important to understand theseprocesses. One of the aims of the ACHILLESteam has been to develop an improvedunderstanding of engineered soildeterioration at the material scale so we candetermine the magnitude of changes in soilproperties, estimate how long this processwill take and identify efficient means ofarresting this deterioration.
