Sampling

• Flowing aggregate stream• Conveyor belt• Stockpiles

• With power equipment• Without power equipment

• Roadways• Transportation units

Methods of Sampling


• From bins, for example• Three increments• Each increment obtained using a

suitable sampling device.• Device must be capable of interrupting

the entire flow of material as it passes off the belt.

Flowing Aggregate Stream


6

Sampling

• Three increments• Production suspended while

sampling• Designated sampling area• Templates useful for defining

sampling area• All material within sampling

area is removed including fines (with a brush)

Conveyor Belts


• Stockpile must be checked for segregationand noted in log.

• Segregation is the separation of varying sizes of aggregate.

• Power equipment is recommended.• Portions collected at various locations

around the main stockpile.

Stockpiles


7

Sampling

• Loader bucket digs straight into pile level to ground

• Loader bucket is raised (perpendicular to the ground) through the entire height of the pile

With Power Equipment


• Portion is dropped onto a clear spot away from the main pile

• The loader is then used to blend and backblade the smaller stockpile



8

Sampling

• The new stockpile can now be sampled at even intervals.

• Material is obtained from each location with a shovel bydigging into the pile.

• The FOUR increments are then combined to comprise thefinal field sample.



If power equipment is not available:• The stockpile is checked for segregation

(and noted in log).• The pile is visually divided into three

even sections.• Portions are obtained from each section

at least 12” below the surface byremoving the outer layer of material.

• The three increments are then combinedto comprise the final field sample.

Without Power Equipment

1 2 3


9

Sampling

In lieu of shoveling:• The stockpile is checked for

segregation (and noted in log).• Sampling tubes may be used.• Sampling tubes may not be

used on stockpiles containing coarse aggregate.

• A minimum of five incrementsmust be collected.

• The five increments are then combined to comprise the final field sample.

Without Power Equipment


Without Power Equipment (Sampling Tube)

1 ¼” min.

6 ft min.


10

Sampling

• Three increments• Sample obtained from uncompacted or loosely-

compacted base or sub base material• Predetermined random locations• Full depth of layer must be sampled• Avoid contamination from underlying material

Roadways


• Railroad cars, barges, trucks

• Power equipment is recommended

• Various levels and random locations

• Three or more trenches

Transportation Units

11

Sampling

• Durable• Strong• Able to be carried

[ 50 lbs. (23 kg) ]• Portion the sample, if necessary• Appropriate container for test

to be performed

Aggregate Moisture Corrections for

Concrete Batching

Moisture Corrections


• Control the amount of mixing water thatactually ends up in mix.

• Biggest source of water to account for• Coarse Aggregate• Fine Aggregate

• Aggregates contain both absorbed andfree water.

• Reference: TDOT Standard Specification501.03

Purpose


32


• Dry Weight• Weight of sample no longer changes after being heated.

• Absorbed Water• Not included in the mixing water .• Determine Percent Absorption of Aggregate.

• SSD Condition (Saturated Surface Dry)• Pores and Cavities are filled with absorbed water, but the surface

is dry.

• Wet Condition• Contains both free and absorbed water.• Free water must be included in the design as mixing water.

Aggregate Moisture Content


1. Determine Percent Free Moisture in Aggregates:% Free Moisture = % Moisture – Absorption

2. Determine SSD Batch Weights

3. Calculate Aggregate Moisture Corrections:Moisture Correction = SSD Weight x % Free Moisture

4. Amount of Water to Subtract from Mixing Waterbased off moisture corrections:

Mixing Water Correction = [CA Moisture Correction (lbs) + FA Moisture Correction (lbs)] / 8.34 lbs/gal

Aggregate Moisture Content Formulas


33


5. Determine Actual CA & FA Batch Weights:Actual Aggregate Batch Weights = SSD Batch Weight + Moisture Correction

6. Determine Actual Water to be Batched:Actual Water Batched = Designed Water – Mixing Water Correction
