However, the influence of basalt fiber morphology on the properties of asphalt binders and mixtures remains inadequately explored. In this study, chopped basalt fiber (CBF) and flocculent basalt fiber (FBF) were selected to make samples for testing the influence of the two types of basalt fibers on asphalt materials. Fluorescence microscopy was used to obtain the dispersion of fiber in asphalt binders. Then, a temperature sweep test and a multiple stress creep recovery (MSCR) test were carried out to appraise the rheological characteristics of the binder. Moreover, the performance of the fiber-reinforced asphalt mixture was evaluated by a wheel tracking test, a uniaxial penetration test, an indirect tensile asphalt cracking test (IDEAL-CT), a low-temperature bending test, a water-immersion stability test, and a freeze\u2013thaw splitting test. The results indicate that the rheological behavior of asphalt binders could be enhanced by both types of fibers. Notably, FBFs exhibit a larger contact area with asphalt mortar compared to CBFs, resulting in improved resistance to deformation under identical shear conditions. Meanwhile, the performance of the asphalt mixture underwent different levels of enhancement with the incorporation of two morphologies of basalt fiber. Specifically, as for the road property indices with FBFs, the enhancement extent of DS in the wheel tracking test, that of RT in the uniaxial penetration test, that of the CTindex in the IDEAL-CT test, and that of \u03b5B in the low-temperature trabecular bending test was 3.1%, 6.8%, 15.1%, and 6.5%, respectively, when compared to the CBF-reinforced mixtures. Compared with CBFs, FBFs significantly enhanced the elasticity and deformation recovery ability of asphalt mixtures, demonstrating greater resistance to high-temperature deformation and a more pronounced effect in delaying the onset of middle- and low-temperature cracking. Additionally, the volume of the air void for asphalt mixtures containing FBFs was lower than that containing CBFs, thereby reducing the likelihood of water damage due to excessive voids. Consequently, the moisture susceptibility enhancement of CBFs to asphalt mixture was not obvious, while FBFs could improve moisture susceptibility by more than 20%. Overall, the impact of basalt fibers with different morphologies on the properties of asphalt pavement materials varies significantly, and the research results may provide reference values for the choice of engineering fibers.<\/jats:p>","DOI":"10.3390\/ma17215358","type":"journal-article","created":{"date-parts":[[2024,11,1]],"date-time":"2024-11-01T11:53:43Z","timestamp":1730462023000},"page":"5358","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Influence of Basalt Fiber Morphology on the Properties of Asphalt Binders and Mixtures"],"prefix":"10.3390","volume":"17","author":[{"given":"Chenhao","family":"Cai","sequence":"first","affiliation":[{"name":"College of Civil Science and Engineering, Yangzhou University, Yangzhou 225127, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keke","family":"Lou","sequence":"additional","affiliation":[{"name":"College of Civil Science and Engineering, Yangzhou University, Yangzhou 225127, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fuxin","family":"Qian","sequence":"additional","affiliation":[{"name":"Administration of Urban Facilities, Yangzhou 225003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peng","family":"Xiao","sequence":"additional","affiliation":[{"name":"College of Civil Science and Engineering, Yangzhou University, Yangzhou 225127, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1148","DOI":"10.1007\/s12221-013-1148-6","article-title":"Melt-spinning Basalt Fibers Based on Dielectric Heating and Steady-state Process Characteristics","volume":"14","author":"Kim","year":"2013","journal-title":"Fibers Polym."},{"key":"ref_2","first-page":"205","article-title":"Solubility of chrysotile asbestos and basalt fibres in relation to their fibrogenic and carcinogenic action","volume":"102","author":"Nikitina","year":"1994","journal-title":"Environ.
