Standard Proctor Compaction Test

Name: Hisham Alrawas

Class: CNST111L, 401

Location: 0118 TA lab

Group Name: Mud Team

Date: 14, April 2017

Equipment Used:

• Moisture Cans numbers: 1, 2, 3

• Compaction mold

• Balance sensitive (g and lb)

• U.S. No. 4 sieve

• Standard Proctor hammer of weight 5.5 lb (24.4 N)

• Large Flat Pan

• Oven with temperature 110 °C

• Plastic squeeze bottle

• Water

• Jack

• Steel straightedge

• Container to hold soil sample for weighting

• Trash can to throw dry soil

Procedure:

1. Obtain all the equipment that will be use in the test.

2. Obtain balance sensitive and weigh empty can simple 1,2,3 plus their caps that will be used to hold soil samples during weighing. Record mass of empty can in data sheet.

3. Obtain 6 lb of air- dry soil on which the compaction test is to be conducted.

4. Pass the soil through the sieve No. 4; collect all of the minus 4 materials in a large pan.

5. Add water to the minus U.S. No.4 material and mix it to bring the moisture content up about 4% to 5% below the estimated optimum moisture content.

6. Determine the weight of the proctor mold + base plate

7. Put the extension to the top of the mold and place it on solid ground.

8. Pour the moist soil into the mold in three equal layers; every layer should be compacted uniformly by the standard proctor hammer 25 times before the next layer of loose soil is poured into the mold.

9. Remove the top attachment from the mold carefully. Also, use the straightedge to excess the soil above the mold.

10. Determine the weight of mold + base plate + compacted moist soil in mold, w2 (lb).

11. Remove the base plate from mold. Use a jack, extrude the compacted soil cylinder from the mold.

12. Take a moisture can and determine its mass, M3

13. From the moist soil extruded in step 11, collect a moisture sample in the can and record the mass of the can + moist soil , M4

14. Add more water about 2% and repeat all steps again by using the leftover moist soil in the pan for the second test. Then record all data to the result sheet.

15. Again, Add more water and repeat all steps again by using the leftover moist soil in the pan form the second test to do the third test. Then record all data to the result sheet.

16. Place the can simple 1,2,3 to the oven to dry.

17. After week, determine the mass of the moisture cans+ soil samples,

18. Throw dry soil of the 3 simples into trashcan and clean all the equipment.
