Abstract

The usability of low-cost iron wire fiber
for the reinforcement of hot asphalt mixtures was investigated with
experimental tests in this study. Five mixtures having different fiber content
of 1%, 3%, 5%, 7%, 9% and control mixtures were prepared. Characteristic
properties of bitumen, aggregate and iron wire used in the mixtures were
determined by thermogravimetric analysis (TGA), conventional bitumen tests,
conventional aggregate tests and metal tensile tests. After optimum bitumen
rate was determined,  Marshall Stability
Test,  Cantabro Tests were performed in
order to measure perfomance of the mixtures. Additionaly, moisture
susceptibility of samples was determined with indirect tensile test. As a
result of indirect tensile tests, indirect tensile strength (S_t) and
indirect tensile strength ratio (ITSR) values were calculated. The results of
the investigations indicate that the addition low-cost iron fiber in the amount
of 1%-3% improved performance of asphalt mixtures. When the used fiber rate was
increased more than 3%, clustering created by fibers was observed by using
stereo-microscobe. Consequently, air voids were increased and bitumen-aggregate
interaction was decreased. Increasing fiber ratio especially, at 7-9 percent
caused compressing, durability and stability problems in the mixture.
