Abstract
The majority of hot asphalt mixtures used in Egypt do not
encounter the standard critical required performance. Resistance to
fatigue and rutting surface deformation are two of the most common
pavement surface defects in Egypt.
Furthermore, the significant increase in traffic loads, severe
climate changes, and ultimate temperature variation have resulted in
pavement surface defects in the short run. Over the last decade,
researchers have attempted to increase flexible pavement’s ability to
withstand new loadings and performance challenges. Using asphalt
mixture modifiers such as polymers led to improve the mechanical
properties of asphalt mixtures and an increase in their service life.
Since bitumen is the primary component of asphalt concrete,
expanding bitumen strength and elasticity is always one of the major
strategies for producing a better mixture. Polymer is added to bitumen
to improve performance using one of two methods: the wet process or
the dry process.
Adapting dry process technique in modifying asphalt concrete
performance is the main scope of this study. Performance evaluation
processes were used in this study to establish the variation in asphalt
mixture properties due to dry process modifications. Performance
analysis included stability, flow, moisture susceptibility, indirect
tensile strength, dynamic modulus test, and flow number.
SUPERPLAST mixture modifier was added to various asphalt
mixtures at varying percentages. The properties of the SUPERPLASTadded
asphalt
mixture
were
compared
to
the

mixture
(control
mix).
SUPERPLAST-enhanced
mixtures
performed
better than conventional mixtures in all performance analysis tests. It was found that the optimal SUPERPLAST content was 5 to 10% of the bitumen weight.
