This paper advances understanding of the key parameters controlling unconfined compressive strength (qu) of lime stabilized fine-grained soils by considering distinct specimen porosities (η), different lime types and contents and several curing temperatures and time periods. A sole empirical relationship is proposed establishing the normalized unconfined compression strength for lime stabilized fine-grained materials considering all porosities, lime contents, curing temperatures and curing periods studied. From a practical point of view, this means that a very limited number of unconfined compression tests on specific lime stabilized fine-grained material specimens molded with a given lime type and amount, porosity, moisture content and cured for a given time period at a particular temperature, should be sufficient to estimate the strength for an entire range of porosities and lime contents at any given condition. Examples of the practicality of the proposed relationship are presented.
