Construction Program Management and Inspection Guide

Portland Cement Concrete Pavement
Verify that the QA procedures maintain effective inspection
at all points of work.
Prior to observing the work:
▼ Examine the prepave meeting minutes.
▼ Become familiar with work processes to be observed.
▼ Discuss procedures established to maintain continuous
and effective inspection at all points of work and proper
liaison between quarry, plant, and paving operations.
▼ Verify that the mix design and material sources have
been approved.
Forms
Examine completed forms in advance of concrete placing
operations:
▼ Take sufficient measurements to ensure compliance
with applicable specifications; identify the location of
measurements by station.
▼ Quality of foundations material under forms.
▼ Line and grade.
▼ Method of securing forms to substrata.
Joints
Verify:
▼ Alignment of the dowel bars meets contract
requirements (generally bars should be parallel to the
centerline of the slab—not necessarily at right angles
with joint, i.e., skewed joints—and parallel to surface
pavement). Document the frequency and results of
checks made after paving operations have been
completed; this is particularly important when dowel
bar inserters are used in the paving train.
▼ Dowel baskets are securely fastened to the substrata.
▼ Dowel bars are lubricated, free of deformities, and
properly capped.
▼ Preformed expansion joints are properly secured;
comment if they are tilted or displaced by strike-off or
finishing equipment.
Paving Operations
Allow sufficient time to become reasonably familiar with all
the operations involved; this should include the beginning
and ending of the day’s operations.
Verify:
▼ Type of equipment used and if in compliance with
contract requirements.
▼ Mixing and delivery time is in compliance with contract
requirements.
▼ Adequacy of batch design and batch control.
▼ Tests for slump, or consistency, and air content.
▼ Methods of making, transporting, and curing concrete
test specimens; when possible, witness flexural or
compressive tests.
▼ Frequency and adequacy of control tests.
▼ Theoretical yield against actual yield to ensure
conformity with the specified mix proportions.
▼ Method of placing concrete.
▼ Finishing operations including micro and macro
texture.
▼ Curing operations.
▼ Joint forming, sawing, depth of cut, uncontrolled
cracking before or during sawing operations, cleaning,
and sealing operations.
▼ Surface smoothness.
