False correct answers Quality assurance is defined as only those planned and systematic
actions taken by the agency to provide confidence that a product or facility will perform
satisfactorily in service. (1-1)
True correct answers A quality assurance program serves as a skeleton or overall framework
necessary for construction quality assurance implementation. (1-4)
True correct answers Joint development and review of quality assurance specifications should
include agency and industry personnel (engineers, inspectors, technicians) who are directly
responsible for construction. (1-5)
True correct answers The same six core elements required for design-bid-build construction
QA programs are also required for design-build construction QA programs. (1-8)
False correct answers Quality control activities include only sampling and testing. Visual
inspection is relegated to the acceptance inspector. (1-10)
True correct answers Quality control plans are project specific documents whose function is
to address specific production facility and field placement processes for individual categories
of work on a construction project. (1-11)
True correct answers Acceptance is the responsibility of the transportation agency. (1-12)
True correct answers The engineering limits are the absolute threshold values for individual
test results (1-15)
True correct answers Quality assurance specifications typically use quality measures. (1-14)
True correct answers Since the objective of the IA comparison is to identify discrepancies or
variability in testing procedures or equipment, IA testing is performed on split samples. (1-
20)
True correct answers If Contractor QC test results are not utilized in the acceptance decision,
a dispute resolution system is not required. (1-21)
True correct answers All Agency Central Laboratories are required under federal regulations
to be accredited through AASHTO Accreditation Program (AAP). (1-23)
True correct answers Personal Qualification/Certification programs should include
requirements for re-certification at 2 to 5 year intervals. (1-26)
True correct answers Each Agency Construction QA Program must meet the requirements of
23 CFR 637B and is required to be approved by FHWA. (1-27)
True correct answers The process of hydration begins immediately when the cement comes in
contact with water. (2-1)
True correct answers The cement paste density and strength are related. (2-1)
, True correct answers AASHTO M 85 (ASTM C 150) stipulate cement types based on
chemical composition. (2-3)
False correct answers Type III cement is known as a low heat of hydration cement. (2-3)
True correct answers According to ACI 318, mixtures using Type I cement should be cured
for 7 days. (2-4)
True correct answers Lowering the heat of hydration in massive concrete structures is
important to prevent thermal cracking. (2-4)
True correct answers A type IP(10) is used to indicate a Portland-pozzolan blended product,
with 10% pozzolan. (2-5)
True correct answers Expansive cement is a special product designed to offset stresses in
concrete caused by drying shrinkage, which when excessive can lead to cracking. (2-6)
True correct answers The time of set for cement paste is determined via a needle penetration
method. (2-7)
False correct answers Cement should be stored in humid or moist environments to ensure
hydration has started prior to being introduced into the concrete mixer. (2-8)
True correct answers A pozzolan is a material which in itself possesses little or no
cementitious activity, but when combined with hydraulic cement, will behave in a
cementitious manner. (3-1)
True correct answers Fly ash tends to increase the consistency of concrete when compared to
mixtures with just Portland Cement. (3-3)
False correct answers Dosages of air entrainment generally need to be lowered when fly ash
is used. (3-3)
True correct answers When compared to mixtures using just Portland cement, mixtures
supplemented with Grade 120 slag cement have greater 28 day strength. (3-5)
True correct answers Fly ash and slag retard the set time of concrete. (3-8)
True correct answers Fly ash and silica fume reduce bleeding in concrete. (3-8)
False correct answers Workability is increased with silica fume. (3-6)
True correct answers When silica fume is added to concrete, the amount of air entrained in
the concrete is reduced significantly. (3-7)
True correct answers Early age strength is reduced when fly ash and slag are used. (3-8)
True correct answers Silica fume has no impact on the time of set or heat of hydration. (3-8)
