ABOUT THE PROJECT
This project consisted of several elements.
Urban Section: Three-inch Minor Rehabilitation HBP Overlay
The urban section consisted of a three-inch HBP
overlay to extend the useful life of the roadway by restoring the
pavement structure. The HBP overlay was placed over the existing
roadway. The roadway consisted of two 12-foot driving lanes. The project
overlaid the existing roadway width with no widening.
Rural Section: Structural Improvement Mill with 8.5 Inches of Concrete Inlay
The rural section consisted of milling 3 inches,
leaving 4 inches of existing HBP in place. The roadway was then overlaid
with 8.5 inches of doweled concrete overlay to extend the useful life
of the roadway by restoring the pavement structure. The roadway
consisted of a 13-foot inside driving lane and a 14-foot outside driving
lane. This project overlaid the existing roadway width with no
widening. The corridor geometrics were brought up to standards. The
highway patrol/truck pullout was included for a preventative maintenance
HBP overlay.
West Frontage Road: Preventative Maintenance HBP
The west frontage road consisted of a
preventative maintenance two-inch HBP overlay over the existing width.
The project overlaid the existing roadway width with no widening.
US Hwy 2 and 26th Street East Intersection Improvements
This intersection improvement consisted of
milling 6 inches and placing a 6-inch doweled concrete overlay
throughout this segment. The roadway consisted of two 13-foot driving
lanes. The project overlaid the eastbound to northbound turn lanes and
the southbound to westbound turn lane width with no widening.
US Hwy 2 and 42nd Street West Intersection Improvements
This intersection improvement consisted of
milling 4 inches and placing a seven-inch doweled concrete overlay
throughout this segment. The project overlaid concrete in the through
lanes and HBP on the turn lanes and shoulders with no widening. The
project repaired the westbound and eastbound lanes.
Install Turn Lanes and Lengthen Existing Turn Lanes to Meet Standards
This project also included installing turn lanes
on US Hwy 2 and County Road 6, which is the temporary bypass route
around the northwest and northeast areas of Williston. The surveying
services for this project included the establishment of a horizontal and
control network for the benefit of the design survey and construction
services. Our field services teams performed a design survey that
included data collection for existing pavement and concrete surfaces,
bridges, culverts, and the perimeter of wetlands, as delineated by
others.
During the construction phase, Ulteig’s surveyors
collected centerline profile and alignment data and designers completed
the design of an improved centerline profile. On previous mill and
concrete overlay projects, common practice was to mill the specified
depth and establish a profile for the concrete pavement. This resulted
in the potential for a large overrun in concrete volume. With the method
Ulteig incorporated into this project, the milling was controlled to
the same profile as the PCC pavement. The result was a very small
overrun in concrete volume.
Because of the development of a large truck stop
complex at the intersection of US Hwy 2 and County Road 6, Ulteig was
directed to complete the design of a four-lane PCC pavement roadway
extension to span the full length of the truck stop development. The
design was completed in a timely manner resulting in no loss of time to
the contractor’s operation.
