2. FIELD COMPACTION CONTROL
The field compaction control consists of the determination of,
1) Dry density
2) Water content

3. Soil Compaction in the Field:
1- Rammers
2- Vibratory Plates 
3- Smooth Rollers
4- Rubber-Tire
5- Sheep foot Roller
6- Dynamic Compaction

4. Soil Compaction in the Lab: 1- Standard Proctor Test
Modified Proctor Test
Soil Compaction in the Lab:
1- Standard Proctor Test
2- Modified Proctor Test
Standard Proctor Test

5. 1) Dry density Measured using core cutter and sand replacement method.
The degree of compaction achieved in the measured by the relative compaction, which defined as the ratio, expressed as a percentage.
Relative compaction,

6. Field Soil Compaction
Because of the differences between lab and field compaction methods, the maximum dry density in the field may reach 90% to 95%.
Dry Density
ZAV
gd max
95% gd max
Moisture
Content
(OMC)

7. Relative compaction
For cohesive soils,
For cohesionless soils,

8. 2) Water content Measured using oven drying method.
In the field water content determined using,
Sand bath method
Alcohol method(the calcium carbide method)
The nuclear method
Proctor needle method

9. Proctor needle test

11. Disadvantages of proctor needle test
It is not reliable for cohesion less soil
not Give the execute result for cohesion less soil
Advantages
Method is fast
Reliable for fine grained soil

12. Thank you..
