What makes it interesting?
What made it unique was the fact that this road was first paved due to the need to be able to quickly move Minuteman intercontinental ballistic misses to the nearby missile silos. The exceptionally narrow width of the crack removal area and the depth of the original section made it particularly difficult to use normal means and methods for the removal and patching.
How HCSS Software assisted with this project
This project was first bid with HeavyBid to get the work and then was managed with HeavyJob. This job was out of state so having the capability of being able to get real-time data from the guys out in the field with their equipment and man hours was instrumental to its success. The HCSS GPS units that were installed on the equipment were also a benefit to create a seamless way for the foreman to keep track of all equipment within the 13 miles that the project stretched. It was also a nice feature to be able to pull in the equipment at the end of the day to input data for time cards. We were able to be able to keep the guys on track and provide them with the necessary manpower and equipment to succeed on this job.
The NDDOT Highway 5 Paving Project was a full-depth crack repair, mill, and pave project in Langdon, ND. The road was originally built on top of stabilized cement and was overlaid numerous times throughout the years. This left the road with an impressive asphalt section that ranged from 13 to 24 inches of asphalt.
The start of the project included full-depth dig outs of the deteriorated transverse asphalt cracks, which would be 2 feet wide and would then need to be patched back in. It was decided early on in the bidding process that some new attachments for the equipment would be necessary, as well as some that were custom made. The need to not only saw through the asphalt but to create enough relief at the joints was considered, and New Look decided to use an excavator-mounted quarry rock saw for sawing the joints. This gave them 2 inches of relief at both sides of the removal limits.
Next they used skid steers with custom-made buckets to be able to remove the asphalt. These were followed up with different skid steers with grading plates to be able to back drag the existing base to prepare it for asphalt that would be used to patch these areas. The combination of the custom-made buckets and hoe-packs mounted to mini-excavators to compact the asphalt proved to be incredibly efficient. This project still proves to be one of the most interesting and unique that New Look has built.
