FDOT ASPHALT PAVING LEVEL 1 EVALUATION SET
QUESTIONS AND ANSWERS SURE A+
✔✔What are PG binders tested for high temperature wise? - ✔✔A 7 day max pavement
temp of 67C
✔✔What are PG binders tested for low temperature wise? - ✔✔-22C
✔✔Friction course has what PG binders in its makeup? - ✔✔PG 76-22 (PMA)
PG 76-22 (ARB)
PG 82-22 (PMA)
✔✔Asphalt cement does what while hot? - ✔✔Acts as a lubricant
✔✔Asphalt cement does what while cold? - ✔✔It becomes a glue and holds the rocks
together
✔✔PG 76-22 (PMA) is especially good at what? - ✔✔Reducing rutting.
✔✔What is an asphalt treated permeable base? - ✔✔Concrete placed over asphalt
✔✔Friction course mixes uses a what kind of aggregate? - ✔✔A polish resistant
aggregate
✔✔What is a polish resistant aggregate? - ✔✔Oolitic limestone (Miami-Dade County)
Granite (Georgia, Alabama, Nova Scotia)
Other Approved Sources
✔✔Asphalt generally has a minimum thickness to be laid at but what determines how
thick? - ✔✔The plans developed by the designer does
, ✔✔What is the difference between Superpave mixes and Friction Course mixes? -
✔✔Polish resistant aggregate and special PMA or ARB binders are used in friction
course mixes.
✔✔A shoulder less than 5 ft with FC-5 can not have what? - ✔✔A joint. Pave the
outside of the mainline and the shoulder at the same time.
✔✔B-12.5 mix can be substituted for what? - ✔✔SP-12.5 TL-B or C can be used in lieu
of the base mix
✔✔B-12.5 mix can also be substituted for what? - ✔✔The contractor may substitute a
SP 12.5 TL-D or E mix in lieu of base mix as long as it does not exceed 500 tons for a
project and at no extra cost.
✔✔GMM stands for - ✔✔Gravity mixture maximum
✔✔GMB stands for - ✔✔Gravity mixture bulk
✔✔GSB - ✔✔stands for gravity stone bulk and is used to calculate the FC-5 target
spread rate and the VMA for dense graded mixes.
✔✔The formula for airvoids is - ✔✔% = 100 x (gmm - gmb / gmm)
✔✔The formula for roadway density is - ✔✔% gmm = (gmb/gmm) x 100
✔✔Determining a Target asphalt spread rate for non FC-5 mixes - ✔✔target spread rate
= thickness x gmm (from mix design) x 43.3
(round to the nearest whole number)
✔✔What is the tolerance for the asphalt spread rate target? - ✔✔+- 5%
✔✔How do you calculate the tolerance for the asphalt spread rate target? - ✔✔Ex:
Target Spread Rate = 165 lb/syds
165 x 0.05 (%5) = 8 lb/syd
Then you use the 8 as a + or - from 165 so the range is from 157 to 173 lbs/syd
✔✔Formula for determining the asphalt spread rate for an FC-5 mix? - ✔✔target spread
rate = thickness x gsb (from mix design) x 40.5
(round to the nearest whole number)
✔✔A prime coat being used on lime rock, sand-clay, shell, and shell stabilized based
have an application rate of what? - ✔✔Limerock: greater than or equal to 0.10 gal/syd
Sand-Clay, Shell, Shell Base: greater than or equal to 0.15 gal/syd
