Once Upon a Time…
There was Holly Asphalt Company dba Navajo Western Asphalt Company mostly PG 70-10 to fixed HMA plants in S. AZ
occasional ADOT project (86 deg PG spread)
ADOT PG strategy changes in 1999 PG 70-16 and PG 76-10 become PG 76-16
use of 110 deg PAV aging
Created significant technical challenge!

The Technical Challenge (1999)
Figure out PG 76-16 for ADOT market Most obvious choice is PMA but…
not enough heat, people, time, or tanks
competition with “modification by process”
need something effective, easy, economical, perform
Research Approach literature review
networking thru industry contacts
develop/test hypothesis thru lab study try polyphosphoric acid

Facts in 2003 About PPA Use in Arizona and New Mexico
5 yrs experience with AMA
We heard of no epidemic of distress
No onerous effect on construction
Mitigating factors to consider? prevalent use of OGFC (NM) and AR-ACFC (AZ)
dry/moderate climate
mandated use of lime on DOT systems
no amine antistrips
Projects seemed okay, but…

October 2003 Performance Review in Arizona
7 projects using AMA PG 76-16
2001 thru 2003 construction
roads in good shape,
contractors got paid,
roads smooth and
quiet, didn’t wash away

Summary
AMA implemented based on specification environment in AZ circa 2000
Up to 8 years performance history in AZ
No epidemic of (or undue) distress
2009 condition similar to 2003 condition
Comparatively easy to manufacture
variability similar to unmodified binders
