Experimental study on mechanical properties of carbon fiber-reinforced hydraulic asphalt concrete
摘要
Abstract
Trabecular bending and uniaxial compression tests of carbon fiber-reinforced asphalt concrete are carried out under different temperatures and different loading rates to study their effects on the mechanical properties,focusing on the stress-strain behavior of trabecular bending and uniaxial compression under different environmental conditions.The test results show that at a temperature as low as-20 ℃ and a loading rate of 1.67 mm/min,flexural tensile strength varies between 1.30 and 11.10 MPa;at the rate of 1 mm/min,compressive strength increases from 2.41 to 31.10 MPa.We have observed that at the same loading rate,temperature has a great influence on flexural tensile strength and compressive strength.When the temperature is fixed at 20 ℃,flexural tensile strength increases from 1.03 to 2.50 MPa as the loading rate increases from 1.67 to 16.7 mm/min,and compressive strength increases from 2.41 to 3.81 MPa as the rate increases from 1 to 10 mm/min.Analysis on the test data of carbon fiber asphalt concrete gives its relationship between flexural tensile strength and compressive strength in the condition of the same temperature and same loading rate.关键词
