Abstract


Clay And Silt Soil Is A Kind Of Soil That Has A Bad Soil Bearing Capacity. One Of Soil
Improvements That We Can Do Is Use A Mixture Of Hydrated Lime. In Addition To More
Economical Reason, It Also Has Good Ability In The Soil Stabilization With Fine Grain Soil.
The Clay Soil Sample Is A Type Of High Plasticity Clay That Taken From Rawa Sragi- Jabung-
East Lampung District And Then The Silt Soil Sample Is Taken From Yosumulyo-East Metro-
Metro City. Based On Previous Experiments, That Soil Is Included In Soft Clay And High
Plasticity Category Which Has High Plasticity Index Value >11%. Based On Unified Soil
Clasification (Uscs), Clay Belong To Cl Category, While Silt Soil Belong To Cl-Ml Category. In
Modified Proctor Compact Test Result, Adding Hydrated lime Prove To Reduce Maximum Density
Value (Γd), And For Optimum Water Content (Ω opt ) Having An Increaces But Not Significant. In
Unconfined Compressive Strength Test, Clay And Silt Soil With Variation Of Curing Time And
Soaked Condition, Soil With Hydrated Lime Mixtured With Modified Proctor Compacted, For
Clay Soil, It Get Qu Optimum Value Increased When It Has 15% Hydrated Lime Content, 28 Days
Of Curing Time, It Get 0,3636 Kg/Cm2. For Silt Soil Qu Optimum Value Inscreased When It Has
15% Hydrated Lime Content And 28 Days Of Curing Time, It Get 0,3411 Kg/Cm2. Hydrated Lime
Adding Could Inscred Unconfined Compressive Strength But With Longer Curing Time Duration
(28 Days) Because The Greater The Qu Soil Value, The Greater The Soil Bearing Capacity.
Keywords: Hydrated Lime, Clay, Silt, Unconfined Compressive Strength, Soil Bearing Capacity
