City schedules six miles of chip-sealing work to streets
By CHUCK CLEMENT, Staff Reporter
This summer's chip-sealing project along several streets in Madison could start as early as next week.|
According to Chad Comes, city engineer, the chip-sealing work might begin on July 29 and the maintenance work on about 6 miles of city streets should be completed during August.
The major street sections involved in this summer's maintenance project include:
-- Highland Ave. from N.W. 2nd St. to the SD-34 bypass curve.
-- N.W. 9th St. from US-81 to N. Washington Ave.
-- Lincoln Ave. from N.E. 2nd St. to N.E. 10th St.
-- N.E. 1st St. from Grant Ave. several blocks eastward.
Additional chip-sealing work is planned along cross streets to the four major street sections.
City officials schedule chip-sealing projects each summer as maintenance work intended to keep Madison's streets in operational shape. During June, the city commissioners approved a five-year infrastructure plan that included providing a total of $632,000 for chip-sealing work from 2014-18.
In doing the maintenance work, workers apply asphalt sealant materials to fill cracks in the asphalt pavement to keep most of any rainfall or other precipitation from flowing into the pavement. When water is kept out, pavement deterioration is slowed.
The asphalt crack sealing can also reduce pavement deterioration by keeping water from penetrating the underlying road base and sub-base layers.
Comes said workers may also apply a fog seal to the rec trail surface.
Fog seals are a method of adding asphalt to an existing pavement surface to improve sealing or waterproofing. They are a spray application of diluted asphalt emulsion primarily used to seal an existing pavement surface.
A fog seal can prevent stone loss in asphalt pavement by holding its aggregate in place. The seal can also improve surface appearance and lengthen the pavement surface's life
Some local residents have questioned the need for workers to have sealed pavement cracks along the Lake Madison Recreational Trail earlier this month. Comes said the rec trail maintenance work was part of the city's maintenance plan for the trail that opened nearly six years ago in October 2007.
The Lake Madison rec trail extends eastward from the city along a 4.2-mile route from Flynn Field in Madison to Johnson's Point at the lake. The construction of the rec trail was a combination of federal and local funding of about 80 percent federal money and 20 percent local financial support.
