LEVEL 1-FDOT ASPHALT PAVING QUESTIONS AND ANSWERS 2025
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
, LEVEL 1-FDOT ASPHALT PAVING QUESTIONS AND ANSWERS 2025
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
