FDOT ASPHALT PAVING LEVEL 1
QUESTIONS WITH DETAILED VERIFIED
ANSWERS
S to N Ans: Downstation
W to E Ans: Downstation
Stationing Ans: Starts at 0+00
Stationing Measurement Ans: 1+00 is 100 feet
Straight Edge is the Ans: Measurement of Pavement smoothness with a
15 foot 4.573 m rolling straightedge
Straight Edge is used to Ans: identify problems
Random sampling Ans: Are random numbers generated usually by a VT
for cores to be extracted from the roadway
How often should you calibrate a Straight edge Ans: Calibrate at the
start of each working period
Using the manual straight edge you find what kind of spot to place the
rolling straightedge? Ans: 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
Ans: 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 Ans: Rolling Straightedge
Manual Straightedge
, Page | 2
Manual Measurement (ruler)
x4 3/16 shims 5mm thick
x4 3/8 shims 10mm thick
When to perform final straightedge Ans: After an entire lane has been
paved
When to perform final straightedge Ans: Pavement should be an
ambient temperature
You cannot use the straightedge until it has been properly Ans:
calibrated
When performing the straightedge procedure Ans: Maintain proper
traffic management and safety
Cross slopes can be either done Ans: Manually or with a smart level
When using a manual cross slope you first Ans: Place a simple level on
pavement
After placing the simple level on the pavement then you Ans: 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 Ans: 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 Ans: Calculate the slope
using the formula
( h / l ) x 100 = slope %
Requirements for the rolling Straightedge Ans: 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 Ans: 3 to 5mph or less
