“…Basalt fiber reinforced the gap-graded asphalt concrete SMA-16(BFSMA-16: Basalt Fiber Stone Mastic Asphalt 16), basalt fiber reinforced the dense gradation asphalt concrete AC-20(BFAC-20:Basalt Fiber Asphalt Concrete 20), and basalt fiber reinforced asphalt-treated permeable base ATB-25(BFATB-25: Basalt Fiber Asphalt-treated Base 25) were selected as factors according to research results from the literature [ 19 , 24 , 25 , 28 , 29 ], the dosage of BFSMA-16 was 0.1%, 0.2%, or 0.3%, the dosage of BFAC-20 was 0.1%, 0.2% %, or 0.3%, and the BFATB-25 content was 0.1%, 0.2%, or 0.3%. The level number was selected according to the principle that the number of factors ≤ the number listed in the orthogonal table, and the level number of the factor was consistent with the level number corresponding to the orthogonal table, which was selected as L 9 (3 4 ).…”
