On May 14, 1991,.Council authorized the readvertisement of the subject projects,

(AC) pavement. Both alternates required the standard 1 year maintenance
warranty for materials and workmanship.

The low bid for ARHK on the Rotunda Drive project was approximately $44,000 (20
percent) more than the low bid for asphalt concrete; and the low bid for ARHM on
the Cherry Street project was approximately $47,000 (40 percent) more than the
low bid for asphalt concrete. Although there are indications that life spans of
major arterials can be increased by 50 percent or more through the use of ARHM
pavements over that of conventional asphalt concrete, there are no indications
that this is the case on non -arterial surface streets. The reason for this is
that traffic counts and wheel loadings control the relatively short life spans
of arterials; and environmental conditions control the relatively longer life
spans of surface streets.
Staff cannot therefore technically justify the total $91,000 additional ARHM
expense for these particular projects, and recommends awarding to the overall
low bidder on each project. Blacktop Materials, the low bidder on each project,
possesses the necessary State Contractor's license and is a member in good
standing. This contractor has done similar work for other agencies, and
references indicated that they have performed satisfactory work.
Staff recommends that final cost savings realized from the above projects be
allocated towards currently unfunded slurry or resurfacing projects within the
City. Staff further recommends that investigations into the use of
asphalt -rubber hot mix pavements continue for major arterials, where life cycle
analyses indicate its use is justified.

2. Allocate final cost savings realized from these projects towards currently
