AGENDA ITEM DETAILS RECOMMENDATION: City staff recommends the City Council approve the preparation of plans and specifications for the Page Avenue (79th Street to 85th Street) Reclaim Project. ARE YOU SEEKING APPROVAL OF A CONTRACT? IS A PUBLIC HEARING REQUIRED? No No BACKGROUND/J U STI FI CATI O N : Page Avenue between 78th Street and 85th Street and 78th Street between Page Avenue and 76th Street are paved streets consisting of 4 1/2" of bituminous surface 44' wide. The pavement is 17 years old and is experiencing thermal cracking (transverse and longitudinal) due to its age. These thermal cracks have allowed water to rehydrate the recycled concrete base. The trapped water has caused these cracks to heave or tent in recent years and severely in winter months creating a very poor profile and very poor rideability. The City attempted to address the issues by providing weep holes through the recycled concrete base allowing water to drain downward away from the pavement. A premium crack sealer was placed over the tenting cracks and up to 12" wide to seal the primary and secondary cracks to minimize water penetration to the base. This solution was completed in the summer of 2019 with a project cost of $35,556.80. Currently, the tenting issue has returned to Page Avenue during the 2019-2020 winter. Though not as severe it is still a bumpy ride along Page Avenue. It appears that the crack sealing material has re -cracked and the water that is getting below the pavement is freezing before reaching the drilled holes as planned. A mill & overlay of Page Avenue from 78th Street to 85th Street and along 78th Street from 76th Street to Page Avenue was planned as part of the 2020 Street Renewal CIP. The CIP estimate is approximately $333,400. Due to the reoccurrence of the tenting along Page Avenue, City staff is recommending that this overlay project be revised. Overlaying the streets in their current condition will not resolve the problems as the cracking and tenting are very likely to reflect through the new surface within a year or two. In lieu of the mill and overlay project, City staff recommends Page Avenue from 79th Street to 85th Street be reclaimed to a depth of 10.5" to combine all the existing pavement and concrete/aggregate layer below creating a move permeable class 5 layer. In addition, the project will involve excavating a portion of the subgrade material and adding a 6" thick clean sand drainage layer with drain tile, then replacing 6" of the reclaim material as aggregate base and paving 4 %" thick. Damaged existing curb and gutter will be replaced as part of the project with a few existing storm structures being rehabbed as needed. The 6" excavated subgrade material (^2580 CY) can be used to fill one of the three City owned commercial/industrial lots in Great River Centre or Waterfront East. The project will also produce excess reclaim aggregate material (-2690 CY) which can be stockpiled at the Public Works yard for use on other projects around the City. We estimate the project construction costs to be approximately $560,000 with a total project cost of $644,000. With approval to complete the plans and specification, the City Council should expect plans and specifications available for approval and authorization for advertisement for bid on February 24, 2020. The project could potentially be awarded to the lowest responsible bidder at the March 23, 2020 City Council meeting.
