ABSTRACT
Ceramic waste materials are abundantly available in Malaysia from the
production of ceramic tiles. In general, ceramic
materials seem to possess low
thermal conductivity characteristics that could reduce pavement temperatures
when used as aggregates in asphalt mixtures. A study was undertaken to look
into the performance of crushed ceramics incorporated in asphalt mixtures to
replace the conventional granite aggregates from sizes 5.0 mm
down including the 75 micron filler. The
replacement was done proportionally with 0%, 20%, 40%, 60%, 80% and 100% ceramic aggregates by
weight of granite. Several mix designs with various percentages of ceramic
aggregates were formulated to determine the marshal properties such as
stability, flow, and resilient modulus. In addition, the potential of ceramic
aggregates in reducing the asphalt pavement temperatures was also studied. The
outcome of the study showed that the ceramic aggregates in the asphalt mixtures
were able to improve the performance of the mixture up to 20% which means there
is a great potential for the use of it in road construction. Besides that, the rate
of heating (RoH) compacted samples subjected to various temperatures dropped
significantly as compared with the control granite specimens. The fatigue
performance of the compacted and temperature conditioned ceramic asphalt
mixtures displayed an interesting trend in terms of strain resistance at
elevated temperatures.
