SUBJECT: REFER TO THE TRANSPORTATION COMMITTEE THE USE OF PBA-6
MATERIAL ON COUNTY CHIP SEAL PROJECTS
SPECIFIC REQUEST(S)OR RECOMMENDATION(S)&BACKGROUND AND JUSTIFICATION
RECOMMENDED ACTION: Refer to the Transportation
Committee the issue -of using PBA-6 material as an alternate ,
or substitute for asphalt-crumb rubber Types 1 and 2 on
county chip seal and other projects. Although there are
questions regarding the proposed product alternative, the
potential for substantial cost savings as well as the
ability to contract. with a company doing business in Contra
Costa County merit additional investigation.
BACKGROUND INFORMATION: Asphalt Service Company
recently submitted a bid to Public Works for a chip seal
project,, proposing to use a petroleum-based product known as
PBA-6 rather than the typical rubber-based product usually
used in projects of this type. The use of this material .
would result in substantial cost savings in terms of
material; however, because it does not have an extensive
test history the durability of the PBA-6 product may be
questionable and result in higher cost in the long run.
Small test strips of PBA-6 have been made in Contra Costa
County. There are apparently other test areas in Southern
California.
