The most important problems in the Iraqi Road network that’s associated
with repetitions of excessive axel traffic loading. This problem will be increased
with availability of moisture, its guide to moisture damage or stripping in hot
mix asphalt .In this study, it is used the low-density polyethylene polymer
(LDPE). It's cheap, and available as local material (particles) in Baghdad Plastic
Factories or bags of soft plastic waste, therefore; it's based by searching about
the active range of developing asphalt upon moisture damage, and searching
about admixture optimum polymer ratio to be added to asphalt to increase
stripping resistance. The local materials were used as AL-Daurah Refinery
asphalt that have penetration (40-50) or, (PG64-16) and nominal aggregate (19)
mm from AL-Nibaie Quarry that’s used in binder asphalt pavement. Prepared
five percentage of polymer (1%,2%,3%,4%,5%) was added to optimum designed
asphalt of (4.8%) by weight and then results were compared with original
asphalt and studying the mechanical, and physical properties of asphalt mix. The
better polymer percentage found as (3%) for developing the specification of
resistance stripping and this characteristic developed to ratio (33.1%) at
temperature (25℃ ), and (26.7%) at (60℃ ).
