RICHLAND COUNTY, NORTH DAKOTA, USA

Crack & Seat: I-29, n/o South Dakota State Line

 

Two North Dakota DOT projects on I-29 north from the South Dakota line included 42 lane miles plus adjacent shoulders of concrete pavement crack & seat and asphalt overlay. Antigo averaged 4.2 lanes miles plus shoulders per day by completing the crack & seat in 10 work days. The northbound lanes were constructed in 2016 and the southbound lanes in 2017.

The North Dakota DOT crack & seat specification required inducing full-depth cracks at a longitudinal spacing between 18” and 24” with minimal spalling of the surface. A combination of Falling Weight Deflectometer (FWD) and visual inspection was used to determine the most effective crack pattern. The cracked pavement was seated by 4 passes with a 40-ton proof roller.

Antigo has completed over 66,000,000 square yards (9,375 lane miles) of crack & seat on highways across the United States and in several other countries since the first project in 1982.
