M0027. MECHANICAL SHAKERS

SIEVING THOROUGHNESS CHECK PROCEDURE

Use pre-sieved, hard, durable aggregate that has been washed, and oven dried at 110 5oC. The aggregate must have an

AASHTO T 96 LA Abrasion loss of 15.0 percent maximum, and an AASHTO T 104 Sulfate Soundness loss of 0.5 percent maximum.

For the Gilson sieve shakers, test the sieve shaker efficiency using the following sample weights:

1/2" sieve: 6,250 grams – 3/4” + 1/2” aggregate

3/8” sieve: 4,750 grams – 1/2” + 3/8” aggregate

# 4 sieve: 2,400 grams – 3/8” + # 4 aggregate

For the 12-inch diameter Rainhart sieve shaker, test the sieve efficiency using the following sample weights:

1/2" sieve: 1,520 grams – 3/4” + 1/2” aggregate

3/8” sieve: 780 grams – 1/2” + 3/8” aggregate

# 4 sieve: 450 grams – 3/8” + # 4 aggregate

# 8 sieve: 450 grams – # 4 + # 8 aggregate

# 30 sieve: 450 grams – # 16 + # 30 aggregate

# 50 sieve: 450 grams – # 30 + # 50 aggregate

# 200 sieve: 450 grams – # 100 + # 200 aggregate

For the 8-inch diameter Rainhart sieve shakers, test the sieve efficiency using the following sample weights:

# 8 sieve: 200 grams – # 4 + # 8 aggregate

# 16 sieve: 200 grams – # 8 + # 16 aggregate

# 30 sieve: 200 grams – # 16 + # 30 aggregate

# 50 sieve: 200 grams – # 30 + # 50 aggregate

# 100 sieve: 200 grams – # 50 + # 100 aggregate

# 200 sieve: 200 grams – # 100 + # 200 aggregate

To obtain the required sample size, separate the approved aggregate by shaking, using the sieves listed above in the tested shaker. Weigh out the individual test sizes from the aggregate retained on each sieve. Record the “Original Sample Weight”

(A) to the nearest 0.1g.

Blend the individual size fractions, and place the entire test sample on the top sieve of the nested sieve stack. Initially sieve the material at the previously established sieve efficiency time. When establishing a sieve efficiency time, use five (5) minutes as a base time for both Gilson floor-mounted units and Rainhart stand-mounted units.

After, sieving, remove the individual sieve from the stack. Hand-sieve for one minute. Hold the individual sieve, provided with a snug-fitting pan and cover, in a slightly inclined position in one hand. Strike the side of the sieve sharply and with an upward motion against the heel of the other hand at the rate of about 150 times per minute, turn the sieve about one sixth of a revolution at intervals of about 25 strokes. Two people shall hand-sieve the Gilson screens over the large soils pans.

Empty the sieve, weigh and record the “Weight Retained After Hand-Shaking (B)” to the nearest 0.1 grams. Weigh and record the material lost during the one-minute hand-sieve to “Pan Weight After Hand-Shaking (C)”. Calculate “Cumulative Weight

After Hand-Shaking (C)” by (A + B). Calculate and record “% Loss (D)” by (B/C) x 100 and if it is less than 1% by mass of the material retained on the individual sieve, then the sieve is passing. If all the sieves are passing, assume that the previously established sieve efficiency duration is correct. If any sieve loss exceeds 1%, re-blend the individual hand sieve-retained and pan-retained materials and place this material on the original individual sieve on which it was tested. (i.e. Place the hand sieved

# 4 material back on the # 4 sieve. Place the hand sieved # 8 material back on the # 8 sieve...etc.) Once the material has been re-introduced to its test sieve, re-nest the sieve stack.

Return the sieve stack into the shaker, and run the unit for an additional three (3) minutes. Again, determine individual sieve losses after hand sieving. Continue this process at three (3) minute run-time intervals until a time is reached when all sieve losses meet the 1 percent maximum loss criteria, or 16 minutes of total shaking time is reached.

M003C. CALIPERS

1. Clean the caliper jaw so that the measuring edges are free of particles that may interfere with the precisions and accuracy of the calipers.

2. Perform the caliper calibration by checking five points at approximately 0, 25, 50, 75, and 100% throughout the range of its capacity. Initiate the test by properly zeroing the digital readout and record the reading. Continue by placing the correct certified gauge block between the caliper jaws to get the desired length for the percentage interval and record the CALIPER READING. Repeat the process until all the desired intervals are measured and recorded.

3. Using the gauge block certification, record the NOMINAL LENGTH and the ACTUAL LENGTH in the appropriate boxes.

4. Calculate and record the DIFFERENCE for each interval.

5. Calculate and record the ACTUAL PERCENT OF CAPACITY.

6. If an individual difference exceeds 0.005 in. (0.125 mm) the calipers fail.

The most stringent measurement in the lab, where calipers are used in testing is to nearest 0.01 in

(0.25 mm).

It is in-house common practice that when there is no specification to determine the precision of an instrument that half of the specified measurement used in testing shall be sufficient.

M004D. DIAL INDICATORS (LENGTH MEASUREMENT DEVICES)

STANDARDIZATION PROCEDURE

1. Ensure that the mechanical action of the gauging mechanism (the movement of the stem) is smooth with no evidence of sticking or binding.

2. Clean the gauge tip and ensure that it is not loose.

3. The support fixture shall provide a clean and smooth testing surface free of nicks and burrs to protect the ends of the gauge blocks.

4. Mount the dial indicator to the support fixture and ensure that the movement of the stem is perpendicular to the testing surface. Allow sufficient space for the placement of the initial gauge block.

5. Place the initial gauge of any suitable size to zero the dial indicator and to give it a reference point.

6. Adjust the height of the dial indicator until the reading is zeroed. Most dial indictors require loading to zero the reading. If the dial indictor is digital and can be zero at any point in the indicator’s range, load the indicator approximately 2 to 5 percent of the full range and zero the gauge.

7. With gauge blocks, verify the linearity of the dial indicator at 0, 25, 50, 75 and 100 percent of full range.

8. Calculate and record the difference and percent error for each interval.

9. Calculate and record the actual percent of capacity.

M0092. FINE SIEVES (OPENINGS < 4.75 MM)

PHYSICAL CONDITION CHECK PROCEDURE

Every opening in the metal wire cloth in a test sieve smaller than No. 4 (4.75 mm) shall be visually inspected for general condition only.

Examine the general condition of the wire cloth. View the sieve cloth against a uniformly illuminated background. If obvious deviations are found, such as weaving defects, creases, wrinkles, foreign matter in the cloth, or wire cloth separation from the frame, the wire cloth is unacceptable.

Note: With the sieve, slightly below eye level, tilt the sieve downward at a slight angle. Rotate the sieve until the sieve cloth wires are approximately 45 from the line of sight. The resulting chevron pattern of the wires allows for easy inspection of the regularity of the weave pattern.

Using AASHTO M92-05 and ASTM E 11 Annex A.1.3 as a reference. The observer shall carefully and methodically examine the appearance of all the openings, in order to detect oversize openings.

Openings whose width deviates by about 10% of the average value are apparent to the unaided eye of a skilled observer. It is probable that all oversize openings exceeding the average value by about

10% or more will be detected. At the same time, it is easily possible to detect sequences of large openings, and local irregularities in the weaving, appearing as distortions in the openings.

Any sieve that is checked and stored for future use, and later put into service, will have the inspection report notated with the date placed into service.

M0092. COARSE SIEVES (OPENINGS 4.75 MM)

PHYSICAL CONDITION AND DIMENSION CHECK PROCEDURE

Every opening in the metal wire cloth in a test sieve larger than No. 4 (4.75 mm) shall be eligible for inspection for compliance with the requirements listed in AASHTO M 92 and ASTM E 11-04 Table 1. Sieves shall be measured with a certified caliper. Results of all measurements for each sieve will be tabulated and compared to nominal dimensions and permissible variations, including maximum limitations of the specifications listed in

AASHTO M 92 and ASTM E 11.

When a sieve has 10 openings or less, measure all openings. In other cases, the examination shall proceed in stages from a survey of general condition, to a methodical scrutiny of individual openings, and finally to measurement of opening sizes for compliance with the tolerances.

Examine the general condition of the wire cloth. View the sieve cloth against a uniformly illuminated background.

If obvious deviations, for example, weaving defects, creases, wrinkles, and foreign matter in the cloth, are found, the wire cloth is unacceptable.

The observer shall carefully and methodically examine the appearance of all the openings, in order to detect oversize openings. Openings whose width deviates by about 10% of the average value are apparent to the unaided eye of a skilled observer. It is probable that all oversize openings exceeding the average value by about 10% or more will be detected. At the same time, it is easily possible to detect sequences of large openings, and local irregularities in the weaving, appearing as distortions in the openings. If an opening is found to be larger than that permissible in accordance with AASHTO M 92 and ASTM E 11-04 Column 6 of Table 1, the wire cloth is unacceptable.

For sieves with 10 or less openings, measure all full openings. For sieves with over 30 openings, measure a minimum of 10 full openings.

Select 10 complete openings in three line segments vertically, horizontally, and diagonally to the direction of the wires and measure ten adjacent openings along each line. When greater numbers of opening are available, choose the fields in such a manner that none of the openings being measured overlap.

Figure 1 Figure 2 If possible, measure the average opening as the distance between parallel wires (measured at the center of the openings) in both directions, being sure to keep the x and y measurements separate. In cases where it is not possible, measure the entire distance of the outside edge to outside edge of the parallel wires and calculate the opening distance by subtracting 2 x the average diameter of the wires. Once the opening data is tabulated, check the data versus the prescribed limits in AASHTO M 92 and ASTM E 11-04 Table 1.

Obtain the average diameter of the wires by measuring 30 different wires selected at random in each direction.

Once the opening data is tabulated, check the data versus the prescribed limits in AASHTO M 92 and ASTM E

M0099. MOISTURE DENSITY MOLDS

CRITICAL DIMENSIONS CHECK PROCEDURE

1. As described in ASTM D 698-00 and D 1557-02, Section A1.4, determine the volume of the mold by using the water method with the base plate and a single plastic or glass plate to the nearest 0.01lbm (1 g) and record.

2. Measure the diameter of the mold with a certified bore gauge six times at the top of the mold and six times at the bottom of the mold spacing each of the top and bottom measurements equally around the circumference of the mold. Record the values to the nearest 0.001 in.

(0.02 mm).

3. Measure the height of the mold with certified calipers making three measurements equally spaced around the circumference of the mold. Record the values to the nearest 0.001 in. (0.02 mm).

4. Calculate the average top diameter (dt), the average bottom diameter (db), and the average height (h).

5. Calculate the volume of the mold and record to the nearest 0.0001 ft3 (1 cm3) using the following equation.

(inch-pound) V = ()(h)(dt + db) 2 / (27,648)

(SI) V = ()(h)(dt + db) 2 / (16,000)

6. Compare the volume results using water versus the dimensional/calculable volume. The difference should be within 0.5%.

M0231. GENERAL PURPOSE AND ANALYTICAL BALANCES

STANDARDIZATION AND CALIBRATION PROCEDURE

1. Clean the weighing pan so that the weighing platform is free of particles that may interfere in the performance of the balance.

2. Turn on the balance and allow it to warm up for at least one hour.

3. If the balance has an external/internal calibration function, follow the manufacturer’s instructions.

4. Perform the balance verification by checking five points at approximately 0, 25, 50, 75, and 100% throughout the range of its capacity. Initiate the test by properly zeroing the balance and record the reading. Continue by placing a certified weight(s) on the weighing pan to get the desired weight for the percentage interval and record the reading. Repeat the process until all the desired intervals are measured and recorded.

5. Using the weights’ certification, record the nominal accumulative weight and the actual accumulative weight in appropriate boxes.

6. Calculate and record the difference and percent error for each interval.

7. Calculate and record the actual percent of capacity.

8. Check the classification or specification requirements against the balance error.

B0028. PRESSURE AGING VESSEL TEMPERATURE AND PRESSURE

TEMPERATURE:

Before any PAV temperature calibration is performed, the calibration technician must determine the digital temperature indicator and thermistor probe offset to yield 100.0C. On the inspection report this data is entered at

“100.0 = Probe @ ________.”

Perform the calibration of the RTD in the PAV device vessel by utilizing a certified temperature device.

The probe is inserted through a pressure coupling. The temperature shall be measured over a 4-hour period at 100C and the temperature read once every hour. An acceptable reading is that where the difference between the thermistor probe and the PAV display reading falls within the tolerance of +

0.1ºC. Under certain circumstances, 90C and 110C may be verified. If there is a difference between the indicated temperature on the PAV’s display and the digital probe’s readout, a user-accessible offset will adjust the temperature to the desired test temperature. Refer to the owner’s manual for a guide to the buttons on the PAV’s front panel.

Caution: Temperature shall be measured with full pressurization; therefore, a tight seal is required.

PRESSURE:

A. The pressure shall be measured with the use of a certified pressure meter such as the Fluke device.

The certified pressure meter shall be connected to the threaded pressure relief area that must be removed for this calibration. Caution must be taken to insure there is a tight seal before full pressurization. The pressure shall be measured over a four-hour period and a reading taken every hour.

B. If there is a difference between the indication pressure on the PAV’s display and the digital probe’s readout, a user-accessible offset will adjust the pressure to the desired test pressure. Refer to the operator’s manual for a guide to the buttons on the PAV’s front panel.

B0240. RTFO OVEN CARRIAGE

ROTATIONAL SPEED CHECK PROCEDURE

A removable mark shall be located on the edge of the carriage/shelf approximately 1/8-inch-wide so that it is visible when the oven door is closed and operating. A reference point in the oven shall be determined which allows determination of one complete shelf revolution. The rotational speed shall be measured using a stopwatch accurate to the nearest 0.1 second. The time required for the shelf to rotate

50 complete revolutions will be measured and the calculated rotation speed recorded to the nearest 0.1 revolutions per minute.
