Effectiveness of Rubberized Asphalt in Stopping Reflection Cracking of Asphalt Concrete

摘要

Experimental rehabilitation techniques that include rubber-asphalt were constructed over an existing asphalt concrete pavement on Route 395 near Ravendale, California. Experimental sections consisted of a dense graded rubberized AC referred to as PlusRide, a dense graded rubberized AC prepared by the Arizona Refining Company ('ARS'), single and double chip seals using the ARS binder and a rubberized stress absorbing membrane interlayer (SAMI). Presents a description and discussion of the mixing, placing and performance to date of the mixtures. After one winter, all of the rubber mixtures are performing better than the control sections of conventional asphalt concrete.
