AGENDA MEMO
City Council
June 21, 2010
A resolution authorizing the
Mayor and City Clerk to execute a contract with North Suburban Asphalt Maintenance. in an amount not to
exceed $35,000.00 for the 2010 Crack Fill Program.
The FY 10/11 Budget includes $49,500.00 for the 2010 Crack Fill Program. Crack sealing is a routine maintenance treatment that will significantly delay roadway deterioration. The sealing material is applied into the cracks before they become too large and before the freeze-thaw cycles have an opportunity to shift the pavement and develop larger cracks (alligatoring). Flexible rubberized asphalt sealants bond to crack walls and move with the pavement, preventing water from entering the road base. The life of the road is extended and maintenance costs greatly reduced over time.
The scope of the program includes all cracks to be routed with a low dust mechanical router to a depth of ¾” and a width of ¾”. Upon completion of the routing, all dirt, debris, and water shall be removed from the cracks. The method of removal is completed by utilizing a blow pipe which blows compressed air from a pull behind conventional air compressor. The crack is then filled with a rubber sealant which is feathered to a width of approximately 3-inches in width. Attachment 1 is the proposed roads and field verified quantities for the program.
Sealed bids were opened on June 17, 2010 at the Darien City Hall. Staff had received 3 competitive bids for the Crack Sealing Program. Attached, please find a bid tally labeled as “Attachment 2” and below please find the results of the vendors. Staff is requesting a $5,000.00 contingency in the event additional cracks are identified in the field.
