Street Sweeping. The streets shall be swept full curb to curb width of all loose aggregates for a period of four (4) weeks, after application of slurry seal. Contractor shall sweep the streets for five (5) consecutive days after application of the slurry. Additional sweeping frequency and location will be on as-needed basis as determined by the Engineer, but shall not be less than once a week.

With deep cracks, settlement may occur, thus requiring application of a second layer of sealant. The level of the sealant must be flush with the existing pavement. All excess sealant shall be removed from the crack with a minimum overlap onto adjacent pavement.
Sealant shall be placed within cracks previously filled (from a previous contract) where the sealant has settled or is missing.

The Contractor may be required to furnish and spread sufficient sand necessary to eliminate tracking or damage to the crack sealant. On all arterial highways where sand will be applied over fresh crack sealant, the Contractor shall post "Loose Gravel" (C6) construction signs. Signs shall be posted from commencement of crack sealing until all sand has been cleaned from the roadway.

Prior to the beginning of slurry operations, Contractor shall furnish, at no cost to the Agency, a current licensed weighmaster's certificate indicating the net weight capacity of the aggregate bin.
Contractor shall supply the Engineer with licensed weighmaster's certificates of weights for all aggregate delivered to the job during the course of each day. Aggregate so certified as being delivered for use in the contract shall be used only in the slurry mixture for this contract. Contractor shall also present weighmaster's certificates for the amount of such aggregate remaining unused at the completion of the contract at no cost to the Agency. Payment shall be determined by deducting the amount of unused aggregate from the total amount of aggregate delivered, all as shown on the licensed weighmaster's certificates. The certificates shall be presented to the Engineer on the same day the aggregate is delivered.
Water (excluding that water in the emulsified asphalt) shall be added at a rate of from 5 to 10 percent by weight of dry aggregate to ensure proper dispersion of the emulsified asphalt and proper workability, while (1) avoiding excess water which would allow separation and settlement of the aggregate, (2) avoiding insufficient water which would result in balling and coagulation in the mixer, and (3) permitting uncontrolled vehicular traffic as specified herein. The exact rate will be determined by the Contractor based upon field conditions subject to approval of the Engineer.

(3) the required insurance certificates and endorsements.
Once City notifies the Bidder of the award, the Bidder will have ten (10) consecutive calendar days from the date of this notification to execute the Contract and supply City with all of the required documents and certifications.
