2018 Pavement Management Plan
For 2018, the pavement management plan has been re-evaluated to focus on pavement preservation – keeping good asphalt roads good. Asphalt streets that were overlaid with 2” overlay, 1” thinlay, and ¾” NovaChip from 2014-2017 will be treated with High Density Mineral Bond (HDMB). Asphalt streets that were overlaid with a 2” overlay in the 6-year period from 2008-2013 will be treated with a microsurface application, MAQS. Over the next two years, this plan will result in treating and preserving asphalt streets that were given a new surface in the past 10 year. The goal of this plan is to reduce the long-term costs by preserving good asphalt pavement with lower-cost solutions.
HDMB (High Density Mineral Bond)
HDMB was developed to meet the demand for effective asphalt preservation on residential roadways without the negative side effects of chip or slurry seals. HDMB was specifically engineered to preserve the native asphalt binder. Effectively preserving the asphalt binder before oxidative damage occurs is recognized as the most cost-effective strategy for managing asphalt pavement.
Vehicles will not be permitted to drive on HDMB treated streets for 24 hours after the application have been completed. This year, roads will be treated in Wards: 7, 8, 9 & 10. The contractor will notify all impacted property owners via door hangers. When the application is complete, HMDB will help extend the life of our asphalt roads. Andale Construction will begin applying High Density Mineral Bond (HDMB) to various area streets the week of June 5th.
With this project, the Department of Public Works will utilize Modified Aggregate Quick Set (MAQS), a proprietary product installed only by Donelson Construction based near Springfield, Missouri. MAQS is a polymer-modified, cold-mix paving system. As a restorative surface, MAQS effectively lengthens a road’s life by 8-12 years, while preventing further damage to its structural integrity. This specially designed system was developed to reduce ravelling, improve skid resistance and improve customer convenience. Roads treated with MAQS can often return to full traffic in 30 minutes or less. The 2018 MAQS project will include treatment of streets in Wards: 1, 7 & 9.
