Summary:
A series of experimental rehabilitation techniques that include rubber-asphalt were constructed over an existing asphalt
concrete pavement on Route 395 near Ravendale, CA.  The experimental sections consisted of a dense graded
rubberized AC referred to as PlusRide, a dense graded rubberized AC prepared by the Arizona Refining Company, single
and double chip seals using the ARS binder and a rubberized stress absorbing membrane interlayer (SAMI).
The report 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 that the control sections of conventional asphalt concrete
placed for comparison.
