These changes are attributed to aggregation of particles. The key characteristic evaluated was the impact of drying temperature on the index properties, compaction characteristics and California bearing ratio. The study found the effect of drying strongly depended on soil type, mineralogy or presence of cementing agents. The observed changes are found to be permanent and the implications are that these changes may affect the field performance of test soils. © 2016, Springer International Publishing Switzerland.AgglomerationChemical propertiesCompactionDryingMineralsSoilsStrength of materialsCalifornia bearing ratioCementing agentsCompaction characteristicsDrying temperatureField performanceIndex propertiesKey characteristicsSoil typesSoil testingcompactionhigh temperaturemineralogyphysicochemical propertyplasticitysoil propertysoil testsoil type
