Abstract: In order to study the effects of temperature and loading rate on the mechanical properties of carbon fiber asphalt concrete, trabecular bending and uniaxial compression tests were carried out at different temperatures and rates to reveal the trabecular bending and uniaxial compressive stress-strain relationships of carbon fiber asphalt concrete under different environmental conditions. The test results show that when the temperature is as low as -20°C and the rate is 1.67mm/min, the flexural tensile strength varies between 1.3MPa~11.1MPa. When the rate is 1mm/min, the compressive strength increases from 2.407MPa to 31.100MPa, and it can be seen that when the rate is the same, the temperature has a great influence on the flexural tensile strength and compressive strength of carbon fiber asphalt concrete. When the temperature is 20°C and the rate increases from 1.67 mm/min to 16.7 mm/min, the flexural tensile strength increases from 1.3 MPa to 2.5 MPa, and when the rate increases from 1 mm/min to 10 mm/min, the compressive strength increases from 2.407 MPa to 3.808 MPa. The relationship between the flexural tensile strength and the compressive strength of carbon fiber asphalt concrete at the same temperature and rate is obtained by analyzing the test data.
