| Summary: | Fatigue tests conducted in an indoor environment for evaluating the anti-reflection crack performance of asphalt overlay are associated with large specimen size and significant dispersion in the test results. To overcome these drawbacks, a test method based on small composite specimens and composite-specimen interface-cracking (CSIC) samples was developed to evaluate the anti-reflection crack performance of asphalt overlays. The effect of glass fiber gratings with three different sizes and no glass fiber grating on the anti-reflection crack performance of the asphalt overlays was compared and analyzed through fatigue tests. The results showed an evident anti-reflection crack effect in the specimens with glass fiber grating; the fatigue test with the CSIC specimens could effectively improve the precision of the test method and reduce the dispersion in the test results. Based on a fatigue test conducted through the ABAQUS finite element analysis software simulation, the feasibility of the evaluation method could be effectively verified. Our study can serve as a basis for the reasonable selection of reinforcing materials to extend the service life of asphalt overlays. |
