1. STRENGTH CHARACTERISTIC
• Unconfined compressive Strength :
|
17.5 – 40 kg./cm.2 |
( 7 days and Soaked water for 2 hours )
|
|
• Flexural Strength ( 28 days ) :
|
9 – 20 kg./cm.2 |
• Elastic Modulus :
|
30,000 – 70,000 kg./cm.2 |
• Soaked CBR :
|
>120% |
• Poison Ratio :
|
0.1 – 0.3 |
2. LOAD CARRYING CAPACITY COMPARE WITH GRANULAR BASE
Polymer Soil Stabilization Base 7 inch thickness can be taken load capacity 3 times of
Granular base at the same thickness ( Data from PCA )
3. DURABILITY
Slake Durability Index (ASTM D 4644 – 87 ) more than 75 %
No Pot-hole, no rutting depth and minimizes cracking.
High Stiffness with no brittle.
Minimizes subgrade pressure and has deflection under loads.
Bridges over weak spots in the subgrade.
4. OTHER PROPERTIES
• Dry Density :
|
1,700 – 2,300 kg./m.2
|
• Water Absorption :
|
>3% |
• Coefficient of Permeability :
|
>10-8 cm./sec. |
5. COMPACTIION
Degree of compaction not less than 95% (Modified Proctor Density)
6. DESIGN CRITERIA
Unconfined Compressive Strength (7 days curing and soaked water for 2 hours before testing) not less than 17.5 kg./ cm.2
