THE PERFORMANCE OF ASP HAL TIC CONCRETE USING VARIOUS FILLERS

Asphalt concretes are made of asphalt binders and aggregates. Although asphalt cement
is predominantly considered the binder holding the aggregates together, the actual
product used to com1ect larger-size aggregate particles is the asphalt mineral filler
mastics. It improves the resistance to permanent deformation in asphalt concrete mixtures
by improvement of rheological properties of asphalt binders through a filler effect, and by
acting as a microcrack arrester as well as improving the bonding interaction between
asphalt binder and aggregates. Samples having different types of filler were prepared and
optimum binder content was determined by Marshall Test procedure. Optimum filler
content was determined considering the filler/bitumen ratio and filler ratio. Creep test,
was carried out to determine the mixture properties and performance. Utilization of waste
material as filler material shall reduce cost and contributes to the conservation of the
environment without compromising the performance of the asphaltic concrete.
