A few field studies have attempted to evaluate the performance of lime stabilized roads, earthfill, etc., several years after the construction of the infrastructure (e.g. Gutschik 1978, Kelley 1988). From these studies, there is a general agreement indicating that the alternation of wet/dry period could be detrimental to the efficiency of lime treatment. It is however difficult to generalize these results since little information is available on the soil types, lime treatment and compaction conditions, etc. in these studies.
