The deterioration of earthworks reduces theirserviceable performance and increases thelikelihood of instability. This can havesignificant impacts on the safe and reliableoperation of the transportation networks thatthey support. These deterioration processesare weather-driven and may lead to failuremany years after construction even in theabsence of increased mechanical loads.Evidence also indicates that climate changewill increase rates of asset deterioration andreduce time to failure. This documentsummarises the key conclusions on assetdeterioration drawn from the ACHILLES bodyof work. A more detailed overview of theACHILLES concept can be found in ReadingGuide 1 [1], the project website (, and the following papers: [2,3].
