°C (+-5)
✔✔If used, how much wetting agent should be used in procedure B? C117 - ✔✔Enough
to produce a small amount of suds when the sample was agitated

nearest .1 Gram or .1%
✔✔How accurate shall balances be for course aggregate or mixtures? C136 -
✔✔readable to the nearest .5 gram or nearest .1%
✔✔What is the significance of C117? - ✔✔Accurate determination of material finer than
75-um in mineral aggregate by washing
✔✔What practice is used for sampling aggregate? - ✔✔D75
✔✔The investigation of potential sample material should be performed by....? D75 -
✔✔A responsible, trained and experienced person
✔✔What should a stockpile be visually inspected of? D75 - ✔✔Discernable Variations
✔✔Where shall a sample be obtained where practicable?D75 - ✔✔From the finished
product
✔✔After a sample is obtained what shall not be done unless required for testing
purposes? D75 - ✔✔Further crushing or manual reduction
✔✔What shall be done if there are any discernable Variations in a stockpile? D75 -
✔✔Corrective action shall be taken to establish homogeneity in the material
✔✔If it is necessary to indicate the degree of variation in a stockpile, what shall be
done? D75 - ✔✔Separate samples shall be drawn from separate areas of the pile
✔✔What increases when sampling from the beginning or the final few tons of a
conveyor belt? D75 - ✔✔The potential of obtaining segregated material
✔✔When should method A be used in a standard proctor? D698 - ✔✔When 25% or
less material is retained on a No. 4 sieve
✔✔When should method B be used for standard proctor? D698 - ✔✔When 25% or less
material is retained on a 3/8" sieve
✔✔When should method C be used for standard proctor? D698 - ✔✔When 30% or less
material is retained on a 3/4" sieve
