Perform the straight edge where in the road
In the outside wheel path
Straightedge and joints
Use the manual and place 1 inch over the joint and measure
Allow 3/8 deficiency
Four things to know to calculate where cores lay
Startinf station
Target yield
Width of road
Random tonnages
Formula to calculate core placement vertically
2000 ÷ target yield x 9 ÷ width = ft per ton of asphalt
then
Random number tonnage x ft per ton = ft away from starting station
so
starting station + feet = core location vertically
Core placement horizontally

, Labeled as offset
Based on width of road
Feet away from edge of pavement
Can't core a road with a thickness of
less than 1 inch
Can't core areas less than how many feet not on the mainland
1000ft
Nuclear Gauges and PQIs are for
Process control not a valid test for densities for the DOT
S to N
Downstation
W to E
Downstation
Stationing
Starts at 0+00
Stationing Measurement
1+00 is 100 feet
Straight Edge is the
Measurement of Pavement smoothness with a 15 foot 4.573 m rolling straightedge
Straight Edge is used to
identify problems
Random sampling
Are random numbers generated usually by a VT for cores to be extracted from the roadway
How often should you calibrate a Straight edge
Calibrate at the start of each working period
Using the manual straight edge you find what kind of spot to place the rolling straightedge?
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
