    QUESTIONS.

    1. What is the title of the video you just watched?
    2. List the tools and apparatus for the experiment.
    3. State the procedure for the experiment.
    4. State the necessary precautions used to obtain adequate readings.
    5. What was the result of the experiment?

    ANSWERS
    1. Title of experiment:
    Determination of California Bearing Ratio (C.B.R) Test

    2. Apparatus: As per IS:2720(part 16)
    a. 5kg of soil sample was taken which passes
    through the selve.
    b. Mixing tools (trowel, spoon etc)
    c. C.B.R test mould with diameter 150mm and
    height of 175mm.
    d. Mould collar and the base
    e. Spacer DISC with diameter of 148mm and
    height of 47.7mm.
    f. Surcharge weight of 2.5kg with hole 53.mm
    g. Slotted weight of 2.5kg.
    h. Penetration plunger with height 100mm and
    base = 50mm.
    j. Loading machine capacity of 5000kg and
    uniform rate of 1.25mm per hour.
    i. Compaction Rammer
    ii. Proving Ring
    iii. Dial Gauges
    iv.Balance
    v. Filter paper
    vi.Mixing Tools
    vii.Tray to contain the specimen
    viii. Measuring Slender

    3. The test Procedure consist of two parts
    which are:
    a. Preparing test specimen
    b. Penetration test.
    The preparing specimen which was Dynamic compaction was the method used.
    Then the following steps was taken:
    i. Soil sample was collected and passed
    through sieve and poured into a metal
    tray.
    ii. It was thoroughly mixed with water to a
    homogeneous state.
    iii. It was compacted into three layers at
    the rate of 56 – uniformly distributed
    bowls for each layer inside the mould.
    iv. The mould moist sample was weighed and
    recorded
    v. The space disc discover that base plate
    were inserted as the filter paper was
    placed out.
    vi. Place the mould in the loading frame and
    its position was adjusted until the
    piston is centered on the specimen.
    vii. The total reading of the penetration
    was recorded.

    4. Precautions:
    a. It was ensured that the reading were
    recorded carefully so as to avoid error
    in computation of result.
    b. It was ensured that the mould was on
    leveled surface while compacting so as to
    have a uniformly distributed blows.
    c. It was ensured that the soil sample was
    compacted into three layers at the rate
    of 56 uniformly distributed blows for
    each layer inside the mould.
    5. The result of the standard load valves.
    Penetration (mm) Unit load kg (f)/cm2
    Total load kg (f)
    2.5 70 1350
    5.0 105 2055.
