Located southeast of Las Vegas, the city of Henderson’s 2011 pavement maintenance program covered several different streets all with different needs. The project was bid by American Pavement Preservation, Las Vegas, NV, in May 2011 and completed November 1, 2011. It used myriad pavement preservation techniques to solve myriad pavement problems on various types of streets.
“The project locations included many different types of surfaces with many different expected outcomes,” says Eric M. Reimschiissel with American Pavement Preservation. “The project included collector streets at business and industrial areas as well as residential streets.”
Various locations, various conditions
The Henderson, NV pavement maintenance program included numerous streets all with different problems.
College Parkway between Horizon Ridge and US 95. Sienna Heights from Eastern to Jefferies. East Gate and Parkson streets. “College was an average cracked surface with some alligator cracked areas, some large, wide cracks that were 1 to 2 inches wide,” says Reimschiissel. “The surfaces were approximately 15 to 18 years old and never had any maintenance.”
The Cape seal application was used to treat cracks and provide a new asphalt surface. “The application was completed at night due to the industrial areas, business office buildings, medical offices and the hospital emergency room entrances on Sienna Heights,” says Reimschiissel.
Marks between Sunset Way and Warm Springs. “These streets had a good surface condition with cracking, so minimal asphalt patching was completed,” he says. “Again, this surface never had any maintenance. A micro surfacing application was completed at night due to shopping center, casino, Wal-Mart and Lowes entrances.”
Downtown streets. “These eight old streets were severely cracked, with uneven and raveled surfaces,” says Reimschiissel. “A crack seal and micro surfacing application were completed to keep these serviceable for new construction. All the work was completed at night due to location of the city offices and all the casino buildings.”
Sunset Way, Sunset Valley Verde, TV 5 Drive and Valley Verde. These surfaces were in average condition with cracking. “The surface was crack sealed and slurry sealed nine years ago,” he says. “During this project, the surface was cape sealed to treat the block cracking and provide a new surface. All of the work was completed at night due to the business office parks, a private elementary school, and a college at the end of Sunset Way.”
Twenty eight residential streets and eight collector streets. These surfaces all had higher-than-normal cracking and a surface with a 12-year-old slurry seal application. They were crack sealed and a Type 2 micro surfacing application was placed for maintenance. These streets were completed during day time hours.
Communication with community
Communication with the traveling public and surrounding community was key to a successful completion of the pavement maintenance project. There were several steps American Pavement Preservation took to effectively communicate traffic disruptions, says Reimschiissel.
All of the businesses were contacted in person and a list kept for the city to verify the notification time and date.Traffic control plans for each individual street and roadway were submitted and approved prior to the beginning of the work. Several meetings with the city Public Works and Traffic Engineer were held in regards to traffic control and work periods. Notifications were placed 7 days prior and 24 hours prior to any work activity. No Parking signs as well as advanced road construction signs were placed 24 hours prior to any applications.
Because of so many different pavement surfaces and issues, there were many types of surface prep completed during the project.
Asphalt patching was completed on the very poor surface areas. Surface motor oil spots, heavy paint and pavement marking tape were ground off with a skid-steer loader rotomill head with 176 bits for a fine grind surface.
