| | 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 BASEPolymer Soil Stabilization Base 7 inch thickness can be taken load capacity 3 times of
Granular base at the same thickness ( Data from PCA )
3. DURABILITYSlake 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. COMPACTIIONDegree of compaction not less than 95% (Modified Proctor Density)
6. DESIGN CRITERIAUnconfined Compressive Strength (7 days curing and soaked water for 2 hours before testing) not less than 17.5 kg./ cm.2 The Chemroad Properties have been proven by the reliable laboratory that Chemroad has improved not only comprehensive strength. , flexural strength, but the moduction of elasticity. Water absorption reduction is also the result of Chemroad properties. INTERNATIONAL TESTING STANDARD
ASTM D422-63, ASTM D4318, ASTM D1632-96, ASTM D1633-96, ASTM D4767
