How much would I have to fall to get a penalty with 3.8%? Will be
asked on our exam.
Original question from old exam was...A paving contractor is about
to embark on a full day of paving and their last air void
measurement from gyratory compacted mix yesterday was 3.8%
which would not be a problem. That is a LOVELY number and
workable mix!

needed stiffness increases. To compensate, increase high
temperature grade. Ex. 55mph (PG 64-22) main road, 20 mph (PG
70-22) exit ramp, and 5mph (PG 76-22) parking lot.

As speed remains constant, As speed decreases and
temperature grades are irrelevant. traffic increases,
As speed increases, the need for As traffic decreases, the need for
higher grades decreases. lower grades increases.

Improved performance stated for rutting, low temp. cracking and fatigue
cracking. Primarily concerned with getting more control over rutting. Low
temp./Fatigue cracking were not as big of a concern.
