Harsh climate, heavy
traffic and, most importantly, use of low-quality aggregates have resulted in
unsatisfactory slurry seal performance in the eastern region of Saudi Arabia.
On the other hand, blast furnace steel slag, a superior aggregate type with
excellent strength and surface properties, is being wasted as a by-product
during the steel manufacturing process. This research was carried out to assess
and improve the performance of slurry seal mixtures in the laboratory using the
Aggregate Blend Improvement Technique by incorporating steel slag aggregate.
Aggregate blends consisting of slag and limestone were evaluated to form an
improved slurry seal mixture that will generate simultaneously greater
wear-resistance and improved bonding characteristics with bitumen. Results
indicate that significant improvements in mixtures are guaranteed through
improved aggregate blending of slag with limestone.
