Experimental study on splitting performance of fiber reinforced asphalt concrete

Abstract

The effects of temperature, fiber length and fiber mixing amount on the splitting performance of asphalt concrete were studied by the splitting test of different fiber mixing amount and length of fiber asphalt concrete at different temperatures. The effect mechanism of fiber on the splitting performance of asphalt concrete was analyzed. The relationship model between the split test parameters of fiber asphalt concrete and temperature, fiber length and fiber mixing amount were established. The results show that under the test conditions, the optimum length of polyester fiber is about 6mm, and the optimum dosage is about 0.2 %.
