“…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 ).…”

“…To investigate the role of basalt fibers in enhancing the road performance of asphalt mixtures, it was found that the optimal dosage of basalt fibers was 0.3%, and the optimal asphalt dosage was 4.63% [ 27 ]. After adding 0.3% basalt fibers to asphalt mixtures, the dynamic stability and maximum destructive strain of the asphalt mixtures improved, leading to optimal overall road performance [ 28 ]. The high and low-temperature stability and water resistance properties of asphalt mixtures were significantly enhanced by incorporating basalt fibers, with 0.3% identified as the optimal dosage [ 29 , 30 ].…”

How to select suitable pavement materials for asphalt pavements according to the functional requirements of layers is still the focus of research by scholars in various countries. However, their effectiveness in combating high-temperature rutting and fatigue cracking in middle and lower layers is limited. To address this issue, a study optimized the incorporation of basalt fibers in different layers to improve road performance based on design specifications. Nine asphalt pavement structures with varying amounts of basalt fibers were assessed using an orthogonal test method. The optimal structure was determined considering factors such as fatigue life and overloading using the finite element method for modeling. Results showed that fiber dosage had a minimal impact on road surface bending subsidence and the location of tensile strain in the lower layer. Shear stresses were concentrated mainly at the outer edges of loads. Optimal dosages of basalt fiber were determined for different layers: 0.3% for the upper layer, 0.1% for the middle layer, and 0.3% for the lower layer. The optimal structure consists of a strong base with a thin-surfaced semi-rigid base layer, with 0.3% for the upper layer and 0.1% for the middle layer. This study provided valuable insights into designing basalt fiber asphalt pavement structures.

In order to study the relationship between the high temperature performance of cold-patched asphalt mixtures and gradation fractal, 13 groups of SMA-13 asphalt mixtures were designed, and high temperature rutting test was carried out to study the high temperature performance of cold-patched asphalt mixtures, and the fractal theory was applied to get the overall fractal dimension D, coarse aggregate fractal dimension Dc, fine aggregate fractal dimension Df, and the predictive model of high temperature performance for cold-patched asphalt mixtures was set up according to the correlation analysis of the high temperature performance and fractal dimension. The high-temperature performance prediction model of cold-patched asphalt mixtures was established based on the correlation analysis between high-temperature performance and fractal dimension. This can reduce the test workload, improve work efficiency, and provide reference for engineering design.

“…Based on the results, the CAM model was adopted to develop the master curves and evaluate the viscoelasticity of recycled mixtures, providing a reference for selecting an appropriate RAP-SBS content according to the specific characteristic of pavement. Eventually, the one-way analysis of variance (ANOVA) [37,38] was conducted to investigate the sensitivity of RAP-SBS content, LOTA, and the incorporation of RA on dynamic modulus and phase angle.…”

For the concerns of investigating the viscoelastic properties of recycled asphalt mixtures incorporating high content reclaimed styrene-butadiene-styrene (SBS) modified asphalt pavement (RAP-SBS), asphalt mixture performance tester (AMPT) was applied to analyze the dynamic modulus and phase angle of recycled mixtures by the influence of RAP-SBS content, temperature, loading frequency, long-term aging (LOTA), and the incorporation of a rejuvenating agent. Master curves of recycled asphalt mixture regarding dynamic modulus and phase angle are developed, and the viscoelastic properties of recycled mixtures within a wide frequency range are characterized with the Christensen–Anderson–Marastean (CAM) model. Eventually, the one-way analysis of variance (ANOVA) was applied to investigate the role of factors on the viscoelasticity of recycled mixtures. The research indicates that (1) the elastic component of recycled mixtures elevates with the increasing of RAP-SBS content and loading frequency; as a result, the high-temperature stability of it enhances, while it is prone to cracking at low temperatures; (2) RAP-SBS content should be selected according to specific characteristics of pavement. For most cases, a content of 50% is recommended; (3) the recycled mixtures incorporating high-content RAP-SBS mixed with a rejuvenating agent has outstanding aging resistance performance; (4) RAP-SBS content is observed to have a significant influence on the viscoelasticity of recycled mixtures.
