Florence Cement Company, under the leadership of Jaime Richards, recently concluded a groundbreaking project aimed at rehabilitating the Alpena Airport Runway 1-19 TDZ Pavement. This ambitious initiative involved the removal and replacement of 60,800 square yards of concrete and asphalt pavement.
The primary objective of the project was to rehabilitate Runway 1-19 TDZ Pavement using non-reinforced concrete. This pavement was constructed on a meticulously prepared underlying surface, adhering to specified lines, grades, thickness, and typical cross-sections outlined in the project plans. The project utilized 32,700 square yards of concrete pavement with a thickness of sixteen inches, amounting to 14,550 cubic yards. Additionally, a 6-inch cement-treated permeable base spanning 33,300 square yards was incorporated into the project under the concrete runway.
A notable aspect of the construction process was the careful planning and execution of the paving lanes. Pilot lanes were poured initially, allowing for a continuous pour, and minimizing wait times for curing. This strategic approach contributed to the efficiency of the project, ensuring a seamless construction process.
One of the key challenges faced during the project was the utilization of cement-treated base (CTB), marking Florence Cement Company's first experience producing this material. The CTB presented difficulties in handling, requiring daily cleaning from batch plant to machine. Overcoming this complexity highlighted the company's adaptability and expertise in handling novel construction materials.
In a commendable move towards sustainability, the project incorporated environmentally friendly practices. The existing runway lanes were removed, and the concrete was crushed, repurposing it as a base material for the mainline pavement. This recycling effort not only reduced waste but also contributed to the overall sustainability of the project.
Florence Cement Company's successful completion of the Runway 1-19 TDZ Pavement rehabilitation project stands as a testament to its commitment to innovation and sustainability in the construction industry. The entire team at Florence Cement Company has set a new standard for runway rehabilitation, combining efficiency, adaptability, and environmental responsibility.
