S to N -ANSWER✅✅✅Downstation
W to E -ANSWER✅✅✅Downstation
Stationing -ANSWER✅✅✅Starts at 0+00
Stationing Measurement -ANSWER✅✅✅1+00 is 100 feet
Straight Edge is the -ANSWER✅✅✅Measurement of Pavement smoothness with a 15
foot 4.573 m rolling straightedge
Straight Edge is used to -ANSWER✅✅✅identify problems
Random sampling -ANSWER✅✅✅Are random numbers generated usually by a VT for
cores to be extracted from the roadway
How often should you calibrate a Straight edge -ANSWER✅✅✅Calibrate at the start of
each working period
Using the manual straight edge you find what kind of spot to place the rolling
straightedge? -ANSWER✅✅✅Locate a flat area with the manual straightedge and
place the rolling straightedge next to the manual straightedge and the gauge should
read 0
The 3/16 and the 3/8 shims go under which wheels during calibration -
ANSWER✅✅✅The outside wheels to measure the low and the center to measure the
high. Gauge should read 3/16 on the 3/16 shim and vice versa for the 3/8 shims. Make
sure the center wheel moves up and down freely.
, Calibration materials for Straightedge -ANSWER✅✅✅Rolling Straightedge
Manual Straightedge
Manual Measurement (ruler)
x4 3/16 shims 5mm thick
x4 3/8 shims 10mm thick
When to perform final straightedge -ANSWER✅✅✅After an entire lane has been
paved
When to perform final straightedge -ANSWER✅✅✅Pavement should be an ambient
temperature
You cannot use the straightedge until it has been properly -ANSWER✅✅✅calibrated
When performing the straightedge procedure -ANSWER✅✅✅Maintain proper traffic
management and safety
Cross slopes can be either done -ANSWER✅✅✅Manually or with a smart level
When using a manual cross slope you first -ANSWER✅✅✅Place a simple level on
pavement
After placing the simple level on the pavement then you -ANSWER✅✅✅Raise the
down end of the level until it is level (bubble center)
After the simple level is lifted until it is level you measure what -ANSWER✅✅✅The
length of the simple level and the height between the (previously down) end of the level
to the pavement
Formula to calculate the manual cross slope -ANSWER✅✅✅Calculate the slope using
the formula
( h / l ) x 100 = slope %
Requirements for the rolling Straightedge -ANSWER✅✅✅Must have a read out gauge,
kept clean and in working order, low and high reading, and marks to the nearest 1/16
(1mm)
Rolling Straightedge pulled at -ANSWER✅✅✅3 to 5mph or less
Deficiencies pointed out with rolling straightedge you should first -ANSWER✅✅✅Mark
the pavement at the center wheel where the needle initially shows a deficiency and
where is ends. Also record location and measurements of deficiency.
