Types of Stabilisation by Mind Map: Types of Stabilisation

1. Subgrade

1.1. Indicative strength after stabilising >5%

1.2. Binders: Addition of lime and chemical binders

1.3. Antipated performance attributes:

1.3.1. Improved subgrade stiffness

1.3.2. Improved shear strength

1.3.3. Reduced heave and shringake

2. Granular

2.1. Indicative strength after stabilising 40%,CBR<70% subbase and base course

2.2. Binders: Other granular materials classified as binders

2.3. Anticipated performance attributes:

2.3.1. Improved pavement stiffness

2.3.2. Improved shear strength

2.3.3. Improved resistance to aggregate breakdown

3. Modified

3.1. Indicative strength after stabilisation: 0.7MPa<UCS<1.0MPa

3.2. Binders

3.2.1. Cementitious binders

3.2.2. Lime

3.2.3. Chemical

3.2.4. Combination

3.3. Anticipated performance attributes:

3.3.1. Improved pavement stiffness

3.3.2. Improved shear strength

3.3.3. Reduced moisture sensitivity

4. Lightly bound

4.1. Indicative strength after stabilisation USC 1.0 - 2.0 MPa

4.2. Binders

4.2.1. Cementitious binders

4.2.2. Lime

4.3. Anticipated performance attributes

4.3.1. Similar to Modified

5. Bound

5.1. Indicative strength after stabilising USC >2.0 MPa

5.2. Binder

5.2.1. Greater quantities of Cementitious binder

5.2.2. Combination of cementitious and bituminous binder

5.3. Anticipated performance attributes:

5.3.1. Increased pavement stiffness to provide tensile resistance

5.3.2. Greatest stiffness and hence load carrying capacity
