The aim of this work is to study the effect of varying curing conditions, namely temperature ( 10o to 60odegrees Celsius) and curing period (2 to 90 days) on the unconfined compressive strength (UCS) and hydraulic conductivity of lime treated clayey soil selected from Mosul city. The soil was treated with (2,4 and 6%) hydrated lime. Test results showed that the UCS was increased with the increase of curing temperature especially at low curing period. On the other hand, hydraulic conductivity in treated soil has increased with temperature compared with that of untreated soil but not with a constant trend. Finally, leaching of treated soil has led to a decline in hydraulic conductivity with time, while the rate of decreasing was found to be more with samples exposed to higher temperature.
