The site is located in the median of Interstate 80 at the Sacramento Regional Transit Light Rail station (WattI-80) parking lot
Two test sections (asphalt and concrete)
University of California Pavement Research Center with the assistance of the Pavement Program and METS will administer calibration program
Calibration tests will be conducted 2 to 4 times per year (March May and July for 2014)
Block Test
rsaquo AASHTO R57-10 Section 53231
rsaquo This test will be conducted on a relatively flat
and level area
rsaquo Itrsquos purpose is to check the height
measurements from the height sensor(s) of
the test vehicle using blocks of known heights
(ie 05 inch 10 inch 20 inch)
46
Bounce Test
rsaquo AASHTO R57-10 Section 53232
rsaquo Itrsquos purpose is to ensures that the data from
the height sensor and accelerometer are
legitimate and being properly combined to
compute the longitudinal elevation profile

Distance Measurement Index Test
rsaquo AASHTO R56-10 Section 84
rsaquo Tests accuracy of profilers distance

Inertial Profiler must be certified within the last 12 months

Contractors must obtain certification from the California Certification Site
MRI for each 01 mile section of a
lane
ldquoMust Grindsrdquo are now defined as ldquoAreas of Localized Roughnessrdquo
Areas of localized roughness uses a continuous IRI for each wheel path with a 25 ft interval
Areas of localized roughness that exceed 120(160) inmile must be corrected regardless of the IRI values of a 01 mile section
51
Caltrans will independently collect profile data
For each 01 mile section the contractorrsquos IRI values must be within 10 percent of Caltransrsquo IRI values
52
Collects data at a high rate of speed (approx 30 mph to 60 mph)
Collects data for both wheel paths simultaneously

The site is located in the median of Interstate 80 at the Sacramento Regional Transit Light Rail station (WattI-80) parking lot
Two test sections (asphalt and concrete)
University of California Pavement Research Center with the assistance of the Pavement Program and METS will administer calibration program
Calibration tests will be conducted 2 to 4 times per year (March May and July for 2014)
Block Test
rsaquo AASHTO R57-10 Section 53231
rsaquo This test will be conducted on a relatively flat
and level area
rsaquo Itrsquos purpose is to check the height
measurements from the height sensor(s) of
the test vehicle using blocks of known heights
(ie 05 inch 10 inch 20 inch)

ldquoMust Grindsrdquo are now defined as ldquoAreas of Localized Roughnessrdquo
Areas of localized roughness uses a continuous IRI for each wheel path with a 25 ft interval
Areas of localized roughness that exceed 120(160) inmile must be corrected regardless of the IRI values of a 01 mile section
51
Caltrans will independently collect profile data
For each 01 mile section the contractorrsquos IRI values must be within 10 percent of Caltransrsquo IRI values

The site is located in the median of Interstate 80 at the Sacramento Regional Transit Light Rail station (WattI-80) parking lot
Two test sections (asphalt and concrete)
University of California Pavement Research Center with the assistance of the Pavement Program and METS will administer calibration program
Calibration tests will be conducted 2 to 4 times per year (March May and July for 2014)
Block Test
rsaquo AASHTO R57-10 Section 53231
rsaquo This test will be conducted on a relatively flat
and level area
rsaquo Itrsquos purpose is to check the height
measurements from the height sensor(s) of
the test vehicle using blocks of known heights
(ie 05 inch 10 inch 20 inch)
