Pervious concrete is regarded as an environmentally sustainable pavement material for its
storm-water management and urban heat island mitigation abilities. However, pervious concrete are
generally made up of single sized aggregates which are prone to lower structural capacity due to
increased porosity. However, compaction technique plays an important role in order to increase the
structural capacity and reduce abrasion losses, there is a need to study pervious concrete with
combinations of different compaction types and its efforts. The various types of compaction technique
with different efforts may lead to choking at the bottom and/or porosity, which may be beyond the
minimum acceptable range for pervious concrete. Therefore, this paper reviews the effect of different
compaction types on mechanical and functional properties of pervious concrete consisting of gradations
with different proportions of coarse aggregates. The compaction characteristics of different mixtures
will be reviewed to identify threshold values of compaction energies, which provide porosity within
acceptable limits of pervious concrete. Further, the compressive strength and abrasion losses will also
be reviewed, which will provide insights into the structural and functional performance characteristics of such pervious concrete mixtures. It is anticipated that this study will provide a brief on effect of different compaction levels and its results on the performance of various pervious concrete mixes.
