Bituminous Concrete Pavement (Full-Depth)
407.09 Surface Tests. The finished
surface of the pavement shall be tested using a California Profilograph
or an approved equivalent or a 5 m (16 ft.) straightedge as specified
below. The Contractor shall remove all objects and debris from
the pavement surface prior to the required profilograph or straightedge
measurements.
(a) 5-m (16-ft.) Straightedge. Pavement
surfaces listed in Table 1 shall be tested in the wheel paths
with a 5-m (16-ft.) straightedge set to the tolerance specified.

A 5 m (16 ft.) straightedge
set to a 5 mm (3/16 inch) tolerance will be used to test the
mainline pavement in lieu of the California Profilograph where
the posted speed, as determined by the contract signing requirements,
is:
(1) Less than or equal
to 70 km/h (40 mph) or
(2) Greater than 70 km/h
(40 mph) with a net project length of less than 1600 m (1 mile).
Surface variations which
exceed the above tolerances shall be marked by the Engineer and
removed by the Contractor with an approved grinding device consisting
of multiple saws. The use of the bush hammer or other impact
devices will not be permitted.
(b) Profilograph.
(1) General. All mainline
pavement shall be tested with a California Profilograph or approved
equivalent. Mainline pavement is defined as all pavement except
that listed in Table 1 located in (a) above and other miscellaneous
pavement surfaces as determined by the Engineer. The profile
will terminate 15 m (50 ft.) from each wide flange beam terminal
joint, bridge approach pavement or existing pavement which is
joined by the new pavement.
The Contractor shall furnish
paving equipment and employ methods that produce a riding surface
having a maximum profile index of 160 mm/km (10 inches/mile)
for any 160 m (0.1 mile) segment except as provided for elsewhere.
When starting up paving
operations or after a long shutdown period, pavement surface
will be tested the first several days with the profilograph as
soon as the surface has cooled sufficiently to allow testing.
For the purpose of surface tests, paving operations for Bituminous
Concrete Pavement (Full-Depth) shall be interpreted as being
concerned with the placement and compaction of the bituminous
concrete surface course. Once the initial pavement smoothness,
paving methods, and paving equipment are acceptable to the Engineer,
daily profiles will be run during the next working day following
placement of the pavement surface course.
The Contractor may use
his/her profilograph on other jobs simultaneously provided such
use will not interfere with the necessary testing as outlined
above and scheduling can be agreed to by the respective Resident
Engineers involved. If the contract does not require the Contractor
to furnish a profilograph, the Department will furnish it.
(2) Profile Index and Price
Adjustments. A daily Profile Index will be determined for each
day's paving. Determination of the Profile Index will be according
to Test Method No. California 526-D. A day's paving is defined
as a minimum of 300 m (1000 ft.) of paving placed in a single
day. If less than 300 m (1000 ft.) is paved, the day's production
shall be grouped with the subsequent day's production. If a profile
Index of 235 mm (15 inches) per km (mile) is exceeded in any
day's production, the initial testing procedures will be resumed
until the index is less than 235 mm (15 inches) per km (mile).
On the first paving day,
a profile up to 235 mm (15 inches) per km (mile) for any 160
m (0.1 mile) segment will be accepted without applicable Price
Adjustment and the profile will be excluded from the average
profile index determined for the project.
Pavement Profiles will
be taken 1 m (3 ft.) from and parallel to each edge for pavement
placed at a 3.6 m (12 ft.) width, or less. When pavement is placed
at a greater width than 3.6 m (12 ft.), the profile will be taken
1 m (3 ft.) from and parallel to each edge and each side of the
planned longitudinal joint. When the pavement being constructed
is contiguous with an existing parallel pavement which was not
constructed as a part of this contract, the profile parallel
with the edge of pavement contiguous with the existing pavement
will not be taken. The profile index for each 160 m (0.1 mile)
section will be the average of the profiles taken.
Acceptance and pay adjustments
for Bituminous Concrete Pavement (Full Depth) will be based upon
the smoothness of the final surface. Measurements on prior lifts
are encouraged.
All areas represented by
high points having deviations in excess of 8 mm (0.3 inches)
in 8 m (25 ft.) shall be corrected by the Contractor with an
approved grinding device consisting of multiple saws. The use
of a bushhammer or other impact devices will not be permitted.
When the average profile
index for the entire project length does not exceed 8 mm/km (0.5
inch/mile), and no 160 m (0.1 mile) section has a profile index
exceeding 160 mm/km (10 inches/mile), the contract unit price
shall be increased according to the following Price Adjustment
Schedule. When the profile index for the 160 m (0.1 mile) section
does not exceed 160 mm/km (10 inches/mile) payment will be made
at the contract unit price for that section. When the profile
index for a 160 m (0.1 mile) section exceeds 160 mm/km (10 inches/mile)
but does not exceed 235 mm/km (15 inches/mile) the contract unit
price for that section will be reduced according to the following
Price Adjustment Schedule.

(3) Correction: Except
for bump corrections, the Contractor will not be allowed to make
corrective grinding to increase his/her percent of pay when the
final profile index is 235 mm/km (15 inches/mile) or less.
At the Contractor's option
and expense, each 160 m (0.1 mile) section of pavement with a
profile index greater than 235 mm/km (15 inches/mile) shall be
either corrected until the measured profile index is less than
or equal to 235 mm/km (15 inches/mile) or removed and replaced.
When the Contractor chooses
the corrective grinding, 90 percent of the contract unit price
will be the maximum amount of pay the Contractor shall receive
for the section of pavement. When the Contractor chooses to remove
and replace the section, the Contractor will be paid the percent
of contract unit price which corresponds to the replaced section's
final profile index.
On those 160 m (0.1 mile)
pavement sections where corrections are necessary, second profilograph
runs will be performed to verify that corrections have produced
a Profile Index of 235 mm/km (15 inches/mile) or less. If the
initial Profile Index is less than 235 mm/km (15 inches/mile),
only the areas representing 8 mm (0.3 inch) deviations in 8 m
(25 ft.) will be reprofiled for correction verification.
All ground areas shall
be neat, rectangular areas of uniform surface appearance, bounded
laterally by lane lines or edges of pavement. Determination of
pavement thickness will be made after the removal of high spots.
