Abstract:Chip seals have been widely used as a pavement maintenance surface treatment due to its competitive cost and construction time. Recently, the research team developed a rubberized chip seal where natural aggregate is replaced with crumb rubber obtained from recycled tires. During this study, laboratory chip seal specimens and a field chip seal section with different crumb rubber replacement ratios were prepared. A total of 108 chip seal laboratory specimens were prepared to investigate aggregate retention using six tests: the standard sweep test, modified sweep test, Vialit test, modified Vialit test, Pennsylvania test, and modified Pennsylvania test.
