This reconstruction and expansion project reconstructed I-75 from Coolidge Hwy. to South Boulevard in Oakland County. Ajax Paving reconstructed a vital segment of a major commuter highway in Oakland County, I-75 from Coolidge Hwy. to South Boulevard. We reconstructed existing travel lanes and added a fourth lane for a future HOV lane. A new design eliminated left-lane ramps, thereby increasing acceleration and deceleration ramp lengths at Adams Road. Adding eight new bridges, expanding the Intelligent Transportation System and reconstructing the Park-n-Ride at Adams Road were also part of the project. We produced over 106,000 cubic yards of concrete to pave over 347,700 sq. yards of 10-inch non-reinforced concrete. The project was completed in 108 calendar days, 20 days under the bid requirements. It also won the 2017 Michigan Concrete Association Award. Only a company like Ajax could take on a challenge like this. Closing and constructing a 7-mile stretch of I-96 in both directions, an essential link traveled by 140,000 drivers every day. The project also required rebuilding 37 bridges, 22 ramps, and 60 business accesses as well as installing new drainage sewers, 15- to 25-foot retaining walls, and a light-emitting diode freeway lighting system. Bidding was in an A+B Contracting Format that factored not only the cost but also the time required for completion. E-construction, a paperless management process, contributed to our efficiency. Automated GPS control for the concrete equipment and automated machining for grading operations also increased productivity. The I-96 project became the largest single-season construction contract in MDOT’s history. In total, it spanned 56 total lane miles, requiring 700,000 square yards of paving and 800,000 tons of aggregate. Best yet, the freeway was reopened to traffic in only 167 days – three weeks ahead of schedule. This project on M-53 (Van Dyke) through Sterling Heights and Warren was 4.82 miles of road reconstruction, concrete surfacing, hot mix asphalt cold milling and resurfacing, drainage, curb, gutter, sidewalk, ramps and drive approaches, signal modernization, signing and pavement marking. Made possible by a $56-million federal stimulus fund, the expansion of M-59 between Crooks and Ryan roads was designed to eliminate bottlenecks on this commuter route connecting Oakland and Macomb counties. In addition to expanding the road from four to six lanes, the project included erecting a barrier between eastbound and westbound traffic, replacing storm sewers, reconstructing 16 ramps, and rebuilding or rehabilitating 9 bridges. 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. M-39 is a major commuter highway in Southeastern Michigan, running through numerous residential communities. When it was time to rebuild three miles of concrete between McNichols and Nine Mile roads, the Michigan Department of Transportation (MDOT) required a very short production schedule and exacting noise control standards. The project also included reconstruction of 24 bridges and 77,000 cubic yards of concrete. Ajax Paving was more than up to the task. Our crews performed exhaustive benchmarking for more than two months before construction began to ensure new noise levels would meet specifications. Also, sixty people worked seven days a week to ensure they met the open date mandated by MDOT. The M-39 project was completed more than two weeks ahead of schedule and earned the Michigan Concrete Association’s Award of Excellence in 2011.
