“…First, it can be seen from Figure 3 that the fiber asphalt concrete mainly cracked along the interface between particles during flexural-tensile failure. The flexural-tensile resistance of asphalt concrete mainly depends on the strength of the asphalt-aggregate interface [11]. The proper addition of fibers to the base asphalt mixture increases the OAC and the thickness of the asphalt membrane.…”

“…Reference [9] carries out a low-temperature beam bending test to disclose the effects of fiber content on lowtemperature performance of fiber asphalt concrete. The mechanism for the low-temperature crack resistance of fiber asphalt concrete has also been discussed, and the lowtemperature performance of fiber asphalt concrete has been evaluated based on the bending test index system [10][11][12][13][14][15][16].…”

Taking the AC-13F mixture as the matrix, this paper carries out beam bending tests on fiber asphalt concrete, using the optimal asphalt content (OAC) determined by Marshall test. The test parameters include temperature, fiber volume ratio and fiber aspect ratio. Based on the test results, the author systematically explored how the three parameters affect the flexural performance of asphalt concrete. In addition, the fiber content feature parameter (FCFP) was introduced to describe the combined effect of fiber volume ratio and fiber aspect ratio on the flexural performance of asphalt concrete, and an FCFP-based model was set up to calculate the flexural performance of polyester fiber reinforced concrete beams at different temperatures. The results show that the flexural-tensile strength of fiber asphalt concrete increases first and then decreases with the rising temperature; the failure strain of fiber asphalt concrete increases with temperature; under different temperatures, the flexural-tensile strength of polyester fiber asphalt concrete increases first and then decreases with the growth in fiber volume ratio or fiber aspect ratio; the optimal FCFP of polyester fibers is 1.13. The research findings shed important new light on flexural-tensile performance of polyester fiber asphalt concrete.

“…Based on the technical standard of SMA mix proportion design in Technical Regulations of Pavement Asphalt Construction in China, referring to relevant research conclusions [1] and through the adjustment of the proportions of mineral aggregate, the paper determined the mix proportion of basalt aggregate SMA, limestone aggregate SMA and basalt and limestone aggregate SMA [2][3] . Subsequently, the system studied the road performance of three SMA-13 asphalt mixture and the mechanical properties of low-temperature anti-cracking performance and high-temperature anti-rutting performance.…”

Three kinds of combination schemes were designed about SMA-13 asphalt mixture. They were basalt aggregate SMA, limestone aggregate SMA, basalt and limestone aggregate SMA. Through the study of low temperature and high temperature test of three kinds of combination, the low temperature performance of basalt and limestone aggregate SMA was better than that of the basalt aggregate SMA; and the high temperature performance was in between, thus providing important experimental data for the limestones replacing basalt in SMA pavement.
