The current research is directed towards
studying the creep compliance characteristics of asphalt
concrete mixtures modified with cement dust. This study can
aid in assessing the permanent deformation potential of
asphalt concrete mixtures. Cement dust was added to the
mixture as mineral filler and compared with regular lime
stone filler. A power law model was used to characterize the
creep compliance behavior of the studied mixtures. Creep
testing results have revealed that the creep compliance power
law parameters have a strong relationship with mixture type.
Testing results of the studied mixtures, as indicated by the
creep compliance parameters revealed an enhancement in
the creep resistance, Marshall stability, indirect tensile
strength and compressive strength for cement dust mixtures
.as compared to mixtures with traditional lime stone filler.
