2020 Pavement Crackseal Improvements IP 20-00

Updated May 8, 2020

Plans and specifications were developed for sealing cracks in bituminous pavement sections on 15.74 miles of public street segments across the City in 2020. These street segments were selected based on age, pavement maintenance history, and Pavement and Surface Evaluation Rating (PASER) values. Street segments that are in relatively close proximity to each other are also typically selected in an attempt to receive lower bid prices for mobilization and traffic control bid items.

Crack seal improvements will be applied to all cracks on some street segments, while only the seam between the pavement and concrete gutter will receive crack seal improvements on other segments. The seam between the pavement and concrete gutter is an area of special concern since gutters convey large volumes of stormwater runoff and the seam between the pavement and gutter runs parallel to the direction of flow. When these seams open up they can allow large volumes of water to infiltrate into and beneath the pavement section. A figure showing which street segments will receive crack seal improvements to the entire pavement surface (red lines) versus streets that will only receive crack seal improvements to the seam between the pavement and concrete gutter (blue lines) can be viewed here.

On April 14, 2020, the City Council approved plans and specifications and authorized advertisements for bids for these improvements. The approved plans can be viewed here. Bids will be opened on May 15, and the City Council will consider accepting bids and awarding a contract for construction on May 26, 2020. Work is currently anticipated to occur between mid-June and mid-August, and will generally takes two to three weeks to complete once work starts.

This page will be updated as new information becomes available, including during construction. Since this work occurs quickly and has little to no impact on the traveling public or abutting properties, letters will not be mailed to notify the public of this work.
