Annual Street Sealing 2010-11 Award of Contract 2 June 6, 2011 Streets selected for treatment were based on information obtained from pavement condition surveys and discussions between Engineering and Transportation Department staff and Public Works Street Maintenance staff. Asphalt rubber chip seals will be used for this year's project as it was for last year. Rubberized asphalt products have been used by Caltrans and other agencies for several years. Asphalt rubber treatments are more flexible than standard treatments, keeping the surface waterproof by preventing the formation or propagation of cracks. They require less preparation by Public Works Services street crews and can be used on streets in poorer condition that typically require more expensive asphalt overlay repairs. Traffic noise is typically reduced when using rubberized asphalt and, as the materials used are made from recycled tires, this treatment also aligns with the City's goal of using "green" products. Although asphalt rubber chip seal is more expensive than a standard chip seal, the City has received a grant from CalRecycle which will reimburse the City for a portion of the cost in using asphalt rubber chip seal at a rate of $1 per square yard. Analysis 'A total of two bids were received on May 12, 2011. International Surfacing Systems submitted the lowest responsive bid at $702,023.00 for the base bid and $132,613.19 for an alternate slurry seal material using black aggregate instead of the traditional grey aggregate. The second bidder had a base bid of $844,000.00 and $152,040.60 for the alternate. The pre -bid engineer's estimate for construction was $761,115.50 for the base bid and $177,380.70 for the alternate. The alternate is not recommended for use at this time due to the cost and reports of uneven pavement wearing. The use of black aggregate will be reevaluated for possible use in future projects.
