Why is aggregate stability important?
The recovery recovery or degradation degradation of soils affects affects.
• Infiltration
• Root growth
• Resistance to water and wi dn erosion.
• Indicator of organic matter content
• Biological activity
• N ti t u r ent cycling in soil
• Crop production and yields
• Soil erosion (wind & water)
Changes in aggregate stability may serve as early indicators of recovery g or de radation of soils.
Agg g re ate stability is critical for infiltration, root growth, and resistance to water and wind erosion.
Aggregate stability is an indicator of organic matter content, biological biological activity activity, and nutrient cycling in soil.
Aggregate Stability Test
1. Sieve and Weigh the Soil Sample.
2. Slowly Wet the soil sample in 0.25 mm Sieve, over a wet terry cloth from bottom up.
3. Wet Sieve the Soil with distilled water.
4. Dry the Aggregates on low air flow.
5. Weigh the Aggregates after drying.
6. Disperse Aggregates in Calgon Solution. Allow the Aggregates in the sieve to soak for 5 min, moving the sieve up and down periodically.
7. Only Sand particles should remain in the Sieve.
8.Dry and Weigh the Sand. Remove all excess water with terry cloth first. Use d i ry ng apparatus.

SOIL TESTING
Standard Penetration Testing (SPT):
Soil exploration, collection and handling of disturbed and undisturbed samples as per IS Standards to any depth irrespective of character of the invisible material by employment of sophisticate equipments (including Rock drilling). Tests on samples such as Analysis of Allowable Bearing Pressure of Soil, Recommendation on foundation etc. and other specific specialized applications.
Proctor Compaction Testing:
Tests to determine Maximum Dry Density and Optimum Moisture content.
California Bearing Ratio Testing (CBR):
Tests to determine strength of subgrades.
Core compaction testing:
Tests to determine strength of soil.
Soil- Electrical resistivity Testing:
Soil sensitivity is defined as the ratio of peak to remoulded shear strength. Problem soil materials are those that show large strength losses on disruption, resulting in catastrophic failure, liquefaction and long run-out distances.
Soil Analysis :
Soil SBC-(Safe Bearing Capacity Testing)
Soil Core Cutting test
Sand Replacement Test
Soil Proctor Density Test
Sand replacement test
Soil CBR Test
Soil Unconfined Compressive Strength Test (UCC)
Soil properties Test such as Sieve Analysis
Soil Specific Gravity
Soil Free Swell Index
Soil Atterberg limits
Rock testing:
1. Compression test
2. Water Absorption test
3. Point Load index test
