Abstract

ABSTRACT
With increasing concerns about sustainability issues combined with the lake of water
resources, using the reclaimed water for the compaction of the granular materials that
are used as a part of the pavement structure has become essential. The reclai med
water is derived from the treatment process of the water obtained from the sewage
system or industry process. The use of reclaimed water is currently getting more
popular in several fields such as irrigations, compaction, and construction. The main
objective of this paper is to examine the effect of using the reclaimed water on the
characteristics of granular material specially the maximum dry density and the
California bearing ratio. Two different types of types of crushed stone base course
materials have been used in this study. The first one is crushed lime stone base course
materials, while the second is crushed dolomite base course materials . The two types
of materials have been examined using the potable water and the reclaimed water. The
results indicated that the reclaimed water can be used effectively in the compaction of
unbounded road materials . In some cases the use of the reclaimed water improved the
California bearing ratio for the compacted materials.
