AGENDA ITEM DETAILS RECOMMENDATION: Staff recommends approval of a quote for crack filling maintenance on Page Avenue. ARE YOU SEEKING APPROVAL OF A CONTRACT? IS A PUBLIC HEARING REQUIRED? Yes No BACKGROUND/JUSTIFICATION: City staff received numerous complaints this past winter season on the condition of Page Avenue between 79th Street and 85th Street. City staff observed that rideability of this street section was extremely poor due to a condition commonly called "tenting". This condition occurs when water is trapped under the pavement and expands when frozen to push the asphalt upwards at normal cracks causing an abrupt elevation change in the street profile. Once warmer weather returns, the ice melts and the pavement typically recedes closer to a more even surface. A combination of factors has caused this issue since Page Avenue was constructed in 2003: ■ The gravel material used as base was a mixture of crushed concrete and asphalt. The specific mixture used for Page Avenue consisted of more concrete than asphalt and provided a very solid base. MNDOT has changed the specification for recycled gravel material for use in street construction since Page Avenue was constructed to lessen the percentage of fine particles used in the gravel base due to this issue. ■ Very small particles within the recycled material high in concrete can seal any pores that allowed water to drain downward into the sand below the gravel base. MNDOT has changed the specification for recycled gravel material for use in street construction since Page Avenue was constructed to lessen the percentage of fine particles used in the gravel base due to this issue. ■ Salt used to melt ice on the street is also trapped under the asphalt and attracts and holds water much like a magnet such that more water is trapped between the asphalt surface and gravel base. ■ Without adequate drainage, water that has intruded through cracks in the pavement becomes trapped between the asphalt surface and gravel base. The trapped water will then freeze and expand, pushing the asphalt upward. The City has developed a plan of action to correct the condition of the roadway: Cracks will be cleaned out using highly compressed air to remove dirt, sand, salt, and other debris to provide space for a pliable adhesive sealant. The City is planning to use a higher grade of crack sealant due to nature of Page Avenue's gravel base to minimize to the extent possible the amount of water penetrating beneath the asphalt. ■ The City will drill 6 -inch diameter holes at each end of the cracks nearest the concrete curb at to a depth of at least 1 -foot to ensure the hole has penetrated the recycled gravel base. These 6 -inch holes will be filled with clean course sand and will act as weep drains to allow any water that does manage to get under the asphalt surface to pass through the recycled gravel base. The combination of sealing the cracks to and providing drainage through the recycled gravel base of the street will minimize or negate the trapping of water, salt, and sand between the asphalt surface and recycled gravel base to prevent tenting from occurring in the future. The City will annually reapply sealant to these cracks or any new cracks that form to minimize the potential for future tenting until the street pavement in need of reconstruction. A quote was received from Bargen Inc., to complete the repairs with assistance from City Staff in the form of traffic control and crack and street cleaning. The quote was for $3.55 per pound with an estimated need for 10,000 lbs. Due to the extra effort the project will need in preparation prior to placement of the mastic material, City staff is most comfortable working with Bargen Inc., due to past performances of their work. City Staff will work with the contractor to have the project completed as soon as possible as cooler weather keeps the transverse cracks wider allowing more mastic material to fill the voids. The Public Works Subcommittee was presented with this information at the April 17th meeting, and recommended the item be placed on the consent agenda for approval. SUPPORTING DOCUMENTS ATTACHED: • Quote — Bargen Inc.

We as a company are taking this serious and we want to protect our workers as well as avoid any fines that might be incurred by not following OSHA regulations. The OSHA standard (29 CFR 1926.1153) requires employers to limit worker exposures to respirable crystalline silica and to take other steps to protect workers. In keeping with the spirit of the law, we are doing everything we can to reduce our employee's exposure to Silica. This includes working towards a solution to suppress the dust at the point of creation, as well as using a Vacuum sweeper truck with a water system in the holding tank to suck the debris from the cracks.
