401.7 -
ACCEPTANCE TESTING:
Acceptance
testing of HMA is the responsibility of the Division.
401.7.1 – Surface
Tolerance: It is the intent of these Specifications that
projects with a
total new pavement thickness of 3 inches (75 mm) and
minimum length of
two lots (1100 ft = 340 m) shall be constructed to provide
a smooth riding
surface. The smoothness of the riding surface will be
determined by the
Engineer using an inertial profilometer or Mays Ride Meter.
The smoothness
testing will generally be accomplished within 30 days after the project is
complete.
The pavement will
be divided into sampling LOTS of one-tenth (0.1) lane
mile (0.16 km)
each. Each LOT shall exhibit a smoothness measurement,
expressed in
inches per mile (millimeters per kilometer) equal to or less than
that shown in the
appropriate Table 401.7.1E or 401.7.1M. When a LOT is
represented by a
smoothness number greater than that shown in Tables
401.7.1E or 401.7.1M, the unit price
shall be adjusted as in 401.13.2.

When compaction
is completed on the course, it shall present a uniform
surface, true
line and grade, conforming to the cross section shown on the
Plans. When
tested with a straightedge, approximately 10 feet (3 meters) in
length, and a
template of the specified dimensions, the finished base course
shall not show a
deviation greater than ¼ inch (6 mm) and the finished wearing course shall not
show a deviation from the required surface greater than 3/16 inch (5 mm).
The Contractor
shall provide the straightedge and template for checking the
surfaces, and an
employee to use them under the direction of the Engineer. Any irregularity of
the surface exceeding the limits specified shall be corrected. Depressions which develop after the initial
rolling shall be corrected by loosening the mixture and adding new material.
High places shall be corrected by removing excess material.
Areas of
completed courses found to be defective shall be removed and
replaced with
approved mixtures laid in accordance with these specifications,
and no additional
compensation will be allowed for materials used or work
involved in replacing defective areas.
501.13-SURFACE TESTS:
The smoothness of the riding
surface will be determined by the engineer
using an inertial
Profilometer or Mays Ride Meter calibrated to an inertial
Profilometer. The smoothness
testing will generally be accomplished within 30
days after the project is
complete.
501.13.1 – Sampling Units: The pavement will be divided
into sampling
LOTS of 0.1 lane mile (0.16
lane kilometer) each. Each LOT shall exhibit a
smoothness measurement,
expressed in inches per mile (millimeters per
kilometer).
501.13.2 – Smoothness
Requirement: Each
sampling unit shall exhibit
a smoothness equal to or less
than 65 inches per mile (1000 millimeters per
kilometer). Sampling units
exhibiting smoothness values greater than 65 inches
per mile (1000 millimeters
per kilometer) shall be paid for at an adjusted price
as follows:
Revised Unit Price = UBP – [(1.00-{127.86-0.429S
}) (0.18 UBP)]ENGLISH
100
=UBP – [(1.00-{127.86-0.028S
}) (0.18 UBP)]METRIC
100
Where UBP = Unit Bid Price
Where S = Smoothness in inches
per mile (millimeters per kilometer).
When the measured smoothness
value exceeds the specified value by 50
percent or more, the LOT
shall be corrected to comply with these
specifications.
