Abstract (2. Language):
Fillers are essential components for producing asphalt concrete mixture,although they are used in very little value in
asphalt,but changes in type and value of fillers can affect significantly on its function improvement. Fillers are used in asphalt
to reduce empty spaces,increase durability and increase permeability and so increase resistance against water. Thus,examining
on durability and knowing the ways for increasing durability of these mixtures are very important.In this research,we used stone
material with standard separation,pure bitumen 60-70 and contained powdered stone fillers,talc,kaolin and some mixture of
these.Talc and kaolin fillers are among natural fillers which their sources are available and inexpensive. In this research,we
determined the percentage of optimal bitumen for each asphalt mixture with different filers by using Marshal experimental
method (AASHTO-D1559standard). We did marshal’s resistance tests (AASHTO-T165) and indirect tension (AASHTOT289)
on some samples which were under the submerged regime (wet samples) and the saturation-solidification-fusion regime
and on some samples which weren’t under this regime (dry samples). Asphalt mixtures with micronized fillers compared with
powdered stone fillers have more Marshal Resistance and tension and also the role of talc and kaolin fillers in increasing the
durability of our samples are very obvious.
