In this paper, UFMs were prepared via in situ polymerization (ISP), followed by an investigation into the road performance of UFM self-healing bituminous mixtures through various tests, including wheel tracking, immersed Marshall, freeze\u2013thaw splitting, low-temperature bending, and three-point bending fatigue tests. Subsequently, the impact of the damage degree, healing duration, and temperature on the self-healing property was discussed. The results indicated that incorporating 3 wt% UFMs into bitumen significantly improved the high-temperature stability and fatigue resistance of the bituminous mixture; for example, its dynamic stability and fatigue life could be increased by about 16.5% and 10%, respectively. However, it diminished the thermal crack resistance, as evidenced by decreases in bending tensile strength and strain by 3.7% and 10.1%, respectively. And it did not markedly improve the moisture susceptibility. Additionally, the maximum improvement observed in the healing rate was about 9%. Furthermore, the healing duration and temperature positively influenced the bituminous mixture\u2019s self-healing, whereas the degree of damage exerted a negative impact, with a relatively significant effect.<\/jats:p>","DOI":"10.3390\/ma17040943","type":"journal-article","created":{"date-parts":[[2024,2,21]],"date-time":"2024-02-21T06:50:22Z","timestamp":1708498222000},"page":"943","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Road Performance and Self-Healing Property of Bituminous Mixture Containing Urea\u2013Formaldehyde Microcapsules"],"prefix":"10.3390","volume":"17","author":[{"given":"Hongliang","family":"Zhang","sequence":"first","affiliation":[{"name":"Key Laboratory for Special Area Highway Engineering of Ministry of Education, Chang\u2019an University, Xi\u2019an 710064, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tong","family":"Yao","sequence":"additional","affiliation":[{"name":"Key Laboratory for Special Area Highway Engineering of Ministry of Education, Chang\u2019an University, Xi\u2019an 710064, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fenglei","family":"Cheng","sequence":"additional","affiliation":[{"name":"Key Laboratory for Special Area Highway Engineering of Ministry of Education, Chang\u2019an University, Xi\u2019an 710064, China"},{"name":"Shandong Hi-Speed Group Co., Ltd., Jinan 250000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"128621","DOI":"10.1016\/j.conbuildmat.2022.128621","article-title":"UV curing study of semi-dense asphalt mixes with different sizes of copper slag\u2014A sustainable rehabilitation and production strategy","volume":"347","author":"Andrea","year":"2022","journal-title":"Constr.
