This item is for patching miscellaneous potholes and over Iaying an existing patch along 80` Street. The potholes deveioped in the fatigued existing mat, because of the concentration of traffic to two lanes during construction. The patch overlaying was the December 1997 water main break patch on 8p` street. This patch was constructed with cold mix asphalt patching material due to the time of year in which it was constructed. As the summer temperatures softened the material, and due to the traffic volumes concentrated over this location the patch became rough and to some extent, impassable. The contractor was then directed to overlay and patch these locations as directed by staff. Bana_shnn. Rnsane.
