In recent years the use of bricks for road construction has increased
unexpectedly in many countries of the world. Specially in the developing countries of
south east Asia, crushed bricks are being used in many civil engineering works including
roads. High crushing strength, low absorptive natural such as gravels and boulders are
not available in Bangladesh except in small quantities in Northern

areas. It is expensive to carry these natural aggregates from their sources to job sites if
the haulage length is high. Again with the increased and continue consumption, those
naturally occurring aggregate sources are being depleted. Due to insurmountable
deficiency of conventional natural aggregates in Bangladesh, crushed bricks are used for
the construction of base and sub-base course of flexible pavements. Good quality brick in
unbound condition has been found to be satisfactory, from strength consideration,
provided they are compacted in a dense grading applying appropriate compacting energy.
Crushed brick aggregate from picked jhama bricks are considerably good for road
construction. They are not only recommended to be used in base, sub-base in unbound
condition but also recommended to be used in bases or surface courses bound with
bituminous material. Bricks aggregate are especially used in Bangladesh and in some
part of India in road base and sub-bases where stone aggregates are not easily available.
