Spanning 26 lane miles from Grand Rapids to Cedar Springs, this project presented a series of unusual challenges. To prevent roadway degradation during construction, Ajax addressed "tented" pavement caused by incompressibles in the old pavement joints and improper expansion in joint maintenance. Additionally, the bridge over 6 Mile Road was too narrow to accommodate conventional construction traffic, and a split/merge traffic plan was required during repairs to keep traffic moving in both directions.
We placed a 6.5-inch unbonded concrete overlay on the existing 40-year-old pavement, bringing the roadway's parabolic surface, superelevation, and crown-cross slope up to current standards. We used a Shilstone-type, well-graded concrete mixture with three aggregates. The mixture contained 40 percent slag cement and used only 294 lb./cubic yard of Portland cement.
If you’ve flown ‘in or out’ of Michigan or Florida, there’s a solid chance you’ve experienced our work firsthand. The same goes for many of the roads and highways in the midwest. Even if you don’t think you’ve driven on our work, there’s a good possibility the safety, drivability, and performance of your vehicle was tested on one of the many test tracks we developed for Ford, GM, and other manufacturers. Even NASCAR® trusts our quality results for their high-spec precision tracks. When we say ‘The Future is Riding on Ajax’... we mean it. Since 1951, we’ve had our hands in some of the most demanding and challenging paving jobs in the Midwest. We’re proud of the work we do and continue to operate guided by the same principles set in place by our founder Herb Jacob; Quality, Safety, and Productivity.
