I-59 Shoulders Trussville
In 2021, A.G. Peltz used Roller Compacted Concrete (RCC) for ALDOT's I-59 shoulders, delivering durable, eco-friendly, and efficient results.
I-59 Shoulders Trussville
A.G. Peltz Group placed 128,000 SY of Roller Compacted Concrete on I-59 interstate shoulders for ALDOT in 2021. As the pilot project with RCC for shoulder reconstruction, ALDOT chose Roller Compacted Concrete due to its advantages, including durability and speed of construction. The existing HMA shoulders were deteriorated, and edge drains were installed about six inches below the existing pavement. These drains limited the depth of the new pavement to five inches, and ALDOT needed a solution that could be installed quickly, meeting interstate drop-off requirements while having adequate structural capacity for anticipated traffic (including temporary truck traffic). According to ALDOT Construction Engineer Gary Smith, “RCC worked well for our requirements. The planer cuts the shoulder down five inches with the RCC equipment following right behind… so there’s no drop-off when the construction is complete. They can do the entire 5-inch lift with one operation.”
A.G. Peltz Group placed the 5-inch thick RCC, ranging from widths of 5 feet on the inside shoulders to 10 feet on the outside shoulders along the nearly 8-mile stretch of roadway. This presented another unique challenge for A.G. Peltz Group, as typical RCC paver screeds require a minimum of 8-foot paving widths. A.G. Peltz Group successfully modified the paver to a width of 5 feet for the inside shoulders without impacting the quality of the placement process. Additionally, this was A.G. Peltz Group and ALDOT’s first use of Portland Cement Limestone (PLC) from Lehigh Hanson, a greener cement alternative to conventional concrete mixes. PLC reduces the amount of clinker and associated emissions required to produce cement, lowering the carbon footprint by about 10%. A.G. Peltz Group is contracted to complete a second phase of I-59 shoulder reconstruction soon.
