GOVERNMENT ENHANCING OUR community 2020 PAVEMENT MANAGEMENT PROGRAM IMPROVES ROADWAYS In 2020 the Village’s Annual Pavement Management Program extended the life of approximately 30 of the Village’s total 224 roadway network lane miles (see map). The maintenance strategies consisted of preservation treatments including rejuvenator seal and chip seal as well as rehabilitation treatments like asphalt mill and overlays. Work began in early summer and was completed in the early fall. To achieve the outcomes of the Pavement Management Program a variety of maintenance strategies are applied to sustain a high-quality pavement network throughout the Village that results in safe, smooth, and visually appealing roadways. The specific strategy selected for each street is determined based on several factors including: traffic volumes; the remaining structural life of the pavement; and types and severity of the distresses present. The goal is to apply the right treatment, to the right road at the right time. Preservation treatments are cost effective surface treatments that are placed on a roadway surface early in its life cycle. The goal of a preservation treatment is to protect the asphalt surface from oxidation caused by air, sun and water. Oxidation leads to the pavement becoming less flexible, which in turn leads to cracking and degradation of the asphalt surface. By applying a preservation treatment early, the life of a roadway is extended, and future rehabilitation costs are minimized. Preservation treatments were applied to 17 lane miles of roadway in 2020. A preservation treatment known as a chip seal was applied in the Green Oaks subdivision. Chip seals are performed on streets that are still in relatively good condition to provide a long lasting, asphalt rich seal that results in a new wearing surface. Ahead of the chip seal application, crack sealing and minor patching is performed to repair and seal these localized areas. PG. 10 GV NEWSLETTER | OCTOBER 2020
GOVERNMENT Rejuvenator Seal in Greenwood Hills Subdivision Chip Seal in Green Oaks Subdivision Mill and Overlay on Yosemite Street Another effective preservation treatment that was performed in 2020 is a rejuvenator seal. This application serves to renew the asphalt binder on the surface of the pavement, thus deterring oxidation and cracking. This treatment is typically applied 3 or 4 years after a pavement has been overlaid with new asphalt. For streets that continue to show very low amounts of cracking, a second application of rejuvenator seal may be applied 6 to 8 years after the hot mix overlay. This year, rejuvenator seals were applied in five residential neighborhoods. Pavement rehabilitation is a more robust maintenance strategy performed later in the life cycle of a roadway to provide additional structural support to the pavement. Rehabilitation was performed on 13 lane miles of roadway in 2020. This year, rehabilitation included major asphalt patching of structural deficiencies, followed by removal and replacement of the top few inches of the roadway surface. This treatment is commonly referred to as a mill and overlay. Rehabilitation was completed in two residential neighborhoods and on Fiddlers Green Circle and Yosemite Street.

GV PUBLIC INFORMATION MEETING HUNTINGTON CALEY OPEN SPACE MASTER PLAN IMPROVEMENTS You are invited to a public information meeting to review the current design for proposed improvements for the final phase of the Huntington Caley Master Plan. The meeting will be held on Wednesday, <strong>October</strong> 21, from 5:30 to 6:30 p.m. at Silo Park (9300 E. Orchard Road). The Huntington Caley Master Plan was adopted by the City Council in 2014. Previously completed master plan improvements include the pedestrian undercrossing of Caley Avenue, extension of the regional trail, braided gardens, Caley Pond improvements, stream and wetland restoration, and park landscape enhancement. The current project being presented will include a small parking area off Caley Avenue, sculpted and landscaped berms around the open space perimeter, an informal lawn, and a natural play area. If you are unable to attend this public meeting and would like information on the current design, please visit Village Voices at greenwoodvillagevoices.com, our new online community engagement tool, starting <strong>October</strong> 14th where you can view the design and provide feedback directly to Village staff. For more information, please call Josh Morin, Parks Project Manager, at 303-708-6113 or email jmorin@greenwoodvillage.com. OCTOBER 2020 | GV NEWSLETTER PG. 11
