Study on Asphalt Concrete Containing Graphite and Carbon Fiber for Self-Monitoring of Strain Using Indirect Tensile Test
This The paper introduces the strain monitoring application of asphalt concrete containing graphite and carbon fibers using the indirect tensile test. By using a dynamic indirect tensile test, the use of asphalt concrete containing graphite and carbon fibers for strain monitoring was investigated and shown to be effective. The electrical resistance increases reversibly with increasing tensile strain under the test. The strain self-monitoring has high sensitivity under either a dynamic indirect tensile test or a static indirect tensile test when its resistance is lower than 10<3>. This strain- monitoring is valuable for weighing, traffic monitoring, border monitoring, and structural vibration control. However, the modulus of resilience is influenced by the addition of graphite. When the graphite content is only 10wt％; the value of the modulus of resilience is equal to that of the original but decreases sharply with increasing graphite content. The modulus of resilience value is 90％ of the original value when graphite the content is 30wt％, but decreases to 70％ when the graphite content reaches 45wt％.
