Why Prime?
Coat and Bond loose material on the surface of the base
Harden or toughen the base surface to provide a work platform
for construction equipment Plug capillary voids in the base
course surface to prevent migration of moisture
Provide adhesion between the base course and succeeding
asphalt course.
We Begin …
in the Lab
Test Materials
Red Clay Sand Ottawa Sand
Water is added to base materials to aid in
compaction
Samples are taken and compacted then oven
dried
Samples are wetted with ~ 5ml
of water-on the surface
Prime is immediately applied
Penetration is measured by cutting
open the sample
And then clearing some space in order to measure depth

Now we take it from the lab to the road
PreparationRoad is pre-wetted 15-25 minutes prior to application with
a water truck.
Too Wet
Too Dry
Just Right!
Roadway is now ready for ePrime
Application Guidelines
Ambient/Surface Temperature: 500 F and
rising.
Application Rate (Gal/Sy): 0.15 - 0.35
ePrime is a single application
Same Day PavingOnce the emulsion has cured (2-10 hours) you are ready to pave

Comparisons with other emulsified products
SS-1HNote that emulsion did not penetrate into the base material and later on as construction traffic drove through, the emulsion tracked out and
peeled off.
CQS-1HOnce again emulsion did not penetrate into the base material and later on as construction traffic drove through, the emulsion tracked out and
peeled off.

Pinto Basin Road, Joshua Tree National
After 15 minutes the emulsion started to break
Air Temperatures were in the low 90’s which assisted in the breaking of the emulsion
25 minutes after application, paving began.
Same day paving vs. 48 hours with a cut back prime.

ePrime over a Cement Stabilized Pulverized Base
Compared to other emulsions or cut back primes, ePrime is the way to go.
40 minutes after application light traffic does not disturb the prime
A cut back prime would not work in a residential setting.
You would not do this with a cut back prime!
Same day paving!
Project
Interstate 80, Summit County, Utah Cement Treated Asphalt Base
8 Miles between Park City Utah and Coalville, Utah
Contractor: Geneva Rock Products, INC.
Base prior to ePrime application
ePrime was applied before the base had cured
Prime coat protected the base from weather and construction traffic for 7 days while the
base cured
“The thing I like about ePrime is that we can shoot it out and pave on it two hours later. Just like MC70, it holds the moisture and locks up the grade. Unlike MC70, the trackout is virtually unnoticeable. Most primes trackout 1-2 miles from the jobsite. ePrime soaks in and sets up right away so you don’t get any pickup of emulsion on your trucks and no tracking of emulsion. We are telling all local and state agencies that ePrime is the only prime we want to use on our paving jobs.”
