Therefore, a clear need exists to identify anti-stripping agents that are compatible with WPA, rather than simply increasing WPA content in asphalt mixtures. This study evaluates the interfacial and mixture-scale performance of SBS-modified asphalt mixtures containing two WPA types, namely coarse WPA and fine WPA, treated with three liquid anti-stripping agents: amine-based agent (AS-Am), organosilane coupling-type adhesion promoter (AS-OS), and ester\/surfactant-based wetting agent (AS-Es). The novelty of this study lies in selecting the anti-stripping system based on WPA\u2013binder adhesion compatibility and validating it through moisture, rutting, rheological, and fracture performance. Binder bond strength, tensile bond strength, shear bond strength, indirect tensile strength\/tensile strength ratio (ITS\/TSR), Hamburg wheel tracking (HWT), multiple stress creep recovery (MSCR), and semi-circular bending (SCB) tests were conducted. AS-OS showed the best overall performance. It increased binder bond strength (BBS) by 52.8% for coarse WPA and 61.5% for fine WPA, while the optimum 0.5% dosage improved tensile bond strength by 81.0% and 97.2%, respectively. AS-OS also increased shear strength by 58.8\u201368.3% and improved TSR to 89.0% and 86.2%. In HWT, C-OS and F-OS reduced final rut depth by 44.0% and 45.8%, respectively. SCB results further showed higher fracture work, especially for F-OS. The findings indicate that proper anti-stripping chemistry is essential for durable WPA\u2013SBS asphalt mixtures.<\/jats:p>","DOI":"10.3390\/polym18131583","type":"journal-article","created":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T00:49:23Z","timestamp":1782434963000},"page":"1583","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Interfacial Compatibility and Performance Evaluation of Waste Plastic Aggregate in SBS-Modified Asphalt Mixtures Using Liquid Anti-Stripping Agents"],"prefix":"10.3390","volume":"18","author":[{"given":"Joohan","family":"Eom","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, Kunsan National University, Kunsan 54150, Jeonbuk, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3131-8586","authenticated-orcid":false,"given":"Kyungnam","family":"Kim","sequence":"additional","affiliation":[{"name":"Pavement Research Division, Korea Expressway Corporation Research Institute, Dong-tansunhwan-daero 17-gil, Hwaseong-si 18489, Gyeonggi-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaehyun","family":"Lee","sequence":"additional","affiliation":[{"name":"Construction Materials Testing Center, Business Development, Dongtan Laboratory, SGS Korea Co., Ltd., 20 Dongtansandan 10-gil, Dongtan-myeon, Hwaseong-si 18487, Gyeonggi-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9841-4882","authenticated-orcid":false,"given":"Tri Ho Minh","family":"Le","sequence":"additional","affiliation":[{"name":"Faculty of Civil Engineering, Nguyen Tat Thanh University, 300A Nguyen Tat Thanh Street, Xom Chieu Ward, Ho Chi Minh City 70000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,25]]},"reference":[{"key":"ref_1","unstructured":"OECD Team (2022).
