City’s micro-surfacing project to be explained at July 9 open house
July 08. 2013 6:00AM
Gone are the days of the quartzite-colored rock chips on city streets – at least for this summer.
Sometime before Aug. 15 the city of Brandon will test out a micro-surfacing polymer product during its annual seal coating of city streets. The new product eliminates the need for rock chips that city residents have become accustomed to in past years. With this new process, the rock chips are already mixed in with the emulsifier, according to project engineer Paul Sanow of Stockwell Engineers. Sanow says city residents will appreciate the new seal coating product.
“It’s dust-less, clean,” he said, “and creates what almost looks like a new surface.”
“It is cleaner,” assures City Administrator Bryan Read. “And we’re not dealing with rock chips, because no matter how much we sweep, they come loose with snow removal and end up on people’s boulevards.”
The benefits of using this product and the city’s plan to seal coat 19 streets on the east side this summer will be explained at a public open house next week. The open house is scheduled from 6:30 to 7:30 p.m. Tuesday, July 9, at the Brandon Municipal Golf Course.
Letters with correlating maps were sent out to about 300 affected homeowner, Sanow said.
In addition to the public meeting, door hangers will be distributed within 24 hours of the project start date as a reminder to residents to remove vehicles from the street during the seal coating process. Message boards will also be placed along Aspen Boulevard, Sanow said.
“We need to get the word out and get it out early and get it out often so people know,” Read said.
Sanow said the micro-surfacing project should take no more than three days, weather permitting. The contract stipulates the work will be done by Aug. 15.
“Communication is going to be important in this first micro-seal project,” Sanow said. “It’s an educational process, and we want property owners to be informed.”
“We’re trying to minimize the impact because there is going to be more interruption than a normal chip-seal project,” he said. “But for only two to three days – that’s it – and there’s no rock in the streets and no rock in the lawns.”
Why is micro-surfacing necessary?
The purpose of an asphalt maintenance project is to prolong the aslphalt life cycle and reduce maintenance cost over that cycle. In the past, the City of Brandon has used a chip seal for asphalt surfacing maintenance.
The new surface treatment is a cold asphalt mixture consisting of graded aggregate (crushed rock), a binder (oil), fines and additives. The surface treatment is used for sealing minor cracks, restoring skid resistance and restoring aesthetic appeal, as well as protecting, preserving and extending the life of the street. It is mixed in a traveling paver truck and then put down through a specially designed spreader box onto the street.
Sanow said Sioux Falls city personnel have been happy with the product, as this will be the sixth year they’re using it.
Similar to the previous chip-seal process, affected residents will be asked to remove vehicles from city streets during the application process. And although the product emulsifies in 20 to 30 minutes, Sanow said residents will not be allowed to drive on the road until the entire area has been addressed.
“Residents will not be able to access their home at some point in time,” Sanow said.
Sanow said residents will have access to Chestnut Avenue throughout the process.
The seal coat crew will close down only one side of the road at a time.
Crews will work long days, Sanow said, with work beginning about 8 a.m. and continuing through 8 p.m.
“They want to get in and get out,” he said. “It will be an inconvenience for a couple of days, it really will, and that’s why communication will be a key factor … so that we can make sure the inconvenience of the project is minimal. That’s why we’re having an open house. That’s why we’ve sent letters and will have message boards.”
In April, the City Council awarded the bid to Intermountain Slurry Seal, Inc. of North Salt Lake City, Utah. The bid, $117,012.74, came in about $48,00 less than the engineer’s estimate of $165,430. The six-figure savings is due to a cooperative bid process with the cities of Sioux Falls and Tea.
“It would be very difficult for us to access a larger contractor with lower rates, so piggy-backing with Sioux Falls works out great,” Read said.
