Positioned to Thrive Pavement Management •Monitoring a pavement’s condition over time by means of a data collection and rating procedure •Use pavement management system/program to optimize strategic application of pavement preservation treatments. •Accomplished by maintaining pavements in a good or better condition while maximizing the life cycle. Positioned to Thrive City Pavement Network •City maintains 311 miles of roads. •Current present-day value of Lakeville’s roads is $366,100,000. •Pavement is the largest City Capital Asset. •Pavement management is essential to have a cost effective program. Positioned to Thrive Pavement Management •The City’s current Pavement Management Program (PMP) started in 2009. •Approximately 25% of local public streets and collector roads are inspected each year; pavements are rated based on general surface condition (Overall Condition Index/OCI). •OCI ratings assist in identifying areas for reconstruction and road rehabilitation and when these improvements should take place.

Pavement Management Positioned to Thrive •City currently seals cracks and pothole patches as only preservation technique. •Other metro cities have moved away from seal coating and are currently using a product called Reclamite Pavement Management Preservation Positioned to Thrive Reclamite •Reclamite is a new product in the upper Midwest. •Reclamite has been used for more than 50 years in the west cost •Reclamite is an asphalt rejuvenator •A maltene-based petroleum product which penetrates into pavement and restore those reactive components (maltenes) that have been lost from the binder due to the natural process of oxidation. •Manufacturer states it adds 5-7 years service life to pavements •In MN Reclamite can potentially have two applications to pavements 5 years apart. •Applied to new pavements 1-3 years old. •Not recommended for high speed roadways. Positioned to Thrive •Benefits: 1.Adds Maltenes back into Asphalt Surface 2.Penetrates top ½” to 3/8” of pavement 3.Becomes “part” of the pavement 4.Waterproofs and seals surface 5.Increases Flexibility 6.Decreases Brittleness 7.Closes Surface Voids Reclamite Positioned to Thrive Reclamite Application Application 5 minutes 10 minutes 12 minutes Positioned to Thrive Reclamite Test Section at 1 Year Positioned to Thrive Treated Untreated Reclamite Test Section at 2 Year Positioned to Thrive Treated Untreated Reclamite Test Section at 4 Year Positioned to Thrive Treated Untreated Reclamite Test Section at 8 Year Positioned to Thrive Treated Untreated Treated Untreated Village of Yorkville, IL Reclamite Test Section at 18 Year Positioned to Thrive Treated Untreated Reclamite Test Section at 20 Year Positioned to Thrive Lakeville Reclamite Demonstration Project-August 20th, 2019 Kenrick Ave (North of Fleet Farm ) Paved November 2018 Application 16 Minutes Sanded at 18 Minutes Kenrick Ave 9/18/19 -4 Weeks Post Treatment Positioned to Thrive Reclamite Demonstration-August 20th, 2019 Innsbrook @Ipava Ave Paved September 2018 Application 5 Minutes Sanded at 18 Minutes Innsbrook –9/18/19 -4 Weeks Post Treatment Positioned to Thrive •St Anthony •Woodbury •Lino Lakes •Richfield •Golden Valley MN Cities Contracted for 2019 •Bayport •Stillwater Township •Lakeland Shores •St Mary’s Point New MN Cities Contracted for 2020 •Eden Prairie •4 other Cities are looking at contracting Reclamite Use In MN Positioned to Thrive Estimate for a Lakeville Reclamite Program* Reclamite 2021 2022 2023 2024 2025 $550,000 $550,000 $550,000 $350,000 $350,000 *Note: Estimate is to treat all eligible streets over the first 3 years and to treat new streets and streets reconstructed or rehabilitated in future years.
