Inspection and Acceptance of
Alternative Pavements
Alternatives
Pre-cast Concrete Pavement
Precast Concrete Pavement
 Precast concrete pavement eliminates the need
for on-site cure time by using prefabricated
concrete panels. The panels are made at a
specialized pre-casting facility ahead of time, then
hauled to the construction site and installed as
needed. The result is a pavement that can be
opened to traffic almost immediately after panel
installation, without compromising the durability
and long-term performance of the pavement
 Precast concrete has long been a proven as
durable pavement, providing 30 years of service
life or longer with minimal maintenance.
Alternatives
Continuous Concrete Pavement
Continuous Concrete Pavement
 Benefits from using unreinforced concrete
slabs are lower construction cost with the
saving on mesh reinforcement and the
potential for continuous pouring.
 The contraction joints of unreinforced
concrete slabs should be relatively
maintenance free.
Alternatives
Roller Compacted Concrete Pavement
Roller Compacted Concrete
Roller-compacted concrete, or RCC, takes its name from the
construction method used to build it. It's placed with conventional or
high-density asphalt paving equipment, then compacted with rollers.
RCC has the same basic ingredient as conventional concrete: cement,
water, and aggregates, such as gravel or crushed stone.
But unlike conventional concrete, it's a drier mix—stiff enough to be
compacted by vibratory rollers. Typically, RCC is constructed without
joints. It needs neither forms nor finishing, nor does it contain dowels or
steel reinforcing.
Withstands extremely heavy loads, no rutting.
Will not deteriorate from spills of fuel or hydraulic leaks.
Will not soften when exposed to high temperatures.
Open to traffic quickly.
No special equipment needed.
These characteristics make RCC simple, fast, and economical.
Continuously Reinforced Concrete
Pavement
Continuously Reinforced Concrete
Pavement
 Type of Portland cement concrete pavement
reinforced with steel re-bars throughout its length
 The use of continuous reinforcement generates
the random cracks in the pavement, while
obviating the need for transverse contraction joints
that appear prone to joint-related distresses and
failures. The cracks can be held tightly by the
reinforcement and should be of no concern so
long as they are uniformly spaced, maintaining the
structural integrity of the pavement.
 The elimination of transverse contraction joints
can offer high riding quality

Inspections
CONCRETE PLACEMENT
 Prior to placement ensure
appropriate expansion joints
 Testing for slump and air
Rate:
 Make control/lab cylinders
 Ensure concrete is cured
properly and in accordance with
approved method.
 Verify temperatures, dispatch
times, cold joints
Inspections and Testing
FINAL INSPECTIONS
 Ensure all forms are removed
 Verify all laboratory cylinder
breaks are in compliance
 Verify line and grade.
 Straight edge joints for
compliance
 Perform an overall visual
inspection of the pavement
