The City of Littleton’s Public Works Department is planning approximately $3.1 million of improvements in its 2018 Pavement Management Program, including $1.4 million in TABOR funds approved by voters last November. This year’s projects include a variety of pavement management techniques throughout the city. There will be some type of preservation on 23 miles of city streets, which is 15% of the total of 161 miles. Crack sealing fills roadway cracks with a flexible sealant to help prevent water penetration into the roadway base, which causes damage during freeze/thaw cycles. Toilet paper will not be used as a blotting material this season. Other options will be used to prevent the sealant from tracking onto tires. Crack sealing will be done north of Littleton Boulevard between Windermere Street and Broadway from mid-May through June. Slurry sealing applies an asphalt emulsion mixed with sand to a roadway surface. This seals the pavement surface to protect it from aging and reduces water penetration into the roadway base through pavement cracks. Slurry sealing will take place on many of the same streets identified for crack sealing in the northeast part of the city. This technique will be used on streets every five years and will be done this summer through August. Chip sealing applies an asphalt emulsion and fractured stone to a roadway surface which is then rolled with a pneumatic roller to set the aggregate into the binder. Any excess loose aggregate is later removed with a sweeper. This process reduces water penetration into the roadway base through pavement cracks and improves skid resistance. Chip sealing is proposed on Prince Street from Jackass Hill Road to Ridge Road, Prince Street from Santa Fe Drive to Belleview Avenue, and Centennial Drive from Federal Boulevard to Prince Street. Striping changes are proposed on Prince Street from Santa Fe Drive to Belleview Avenue which will modify the street to one travel lane and one dedicated bike lane in each direction. Turn lanes will also be modified to improve sight lines and safety. This technique will be applied every six to seven years and will be done from July through September.
Milling and overlaying removes and replaces the top layer of asphalt. Damaged concrete curb and gutter are also replaced and curb ramps improved to ADA standards. Projects are proposed on Windermere Street from Littleton Boulevard to Belleview Avenue, Jackass Hill Road from Mineral Avenue to Prince Street, the two Long Circles in the Southpark neighborhood, and Mineral Drive/Utica Drive from Platte Canyon Road to Mineral Avenue. Pavement striping will be improved on both Windermere Street and Jackass Hill Road to enhance safety and provide dedicated bike lanes where possible. The crosswalk at the top of Jackass Hill Road will have a median added to improve crosswalk visibility and pedestrian safety. These projects will be constructed from July through October. Around three miles of neighborhood streets will be milled and overlayed this summer. Pothole patching will be done throughout the city. These projects will take place from June through September. A map of the projects is available on the city’s website.
