American ST™ Assembly (Flatwork)
Reliably deliver serviceable saw-cut contraction joints and achieve joint stability measurements of 0.01 inches (0.25 mm) in concrete flatwork applications with the American ST™ Basket Assembly.

The alternating plate orientation provides maximum construction tolerances of +/- 3 inches and is ideal for large laser screed placements. The plate shape minimizes restraint by allowing lateral movement of adjacent slabs to minimize random cracking. Designed for industrial and commercial concrete flatwork projects with two-directional dowelling. The American ST™ basket is easy to install and reduces job site tripping hazards. Project designs should incorporate the American Diamond™ system at formed construction joints.
The American Highway Dowel Optimizer™ should be used to provide the most sustainable, cost-effective design for the size and spacing of plate dowels for the specific application.
American Highway streamlines dowel design with advanced tools, customizing dowel basket dimensions for cost-effective, high-performance results in demanding environments. Our engineers use the proprietary Dowel Optimizer™ to calculate ideal dowel size, spacing, and performance, meeting safety standards and reducing installation costs while ensuring long-lasting durability under heavy traffic.
High Performance
Armour Coat™ high-performance dowel bar is a solid carbon steel round bar that utilizes a multi-layered fusion-bonded totally encapsulated epoxy powder system. Armour Coat dowels are typically specified in pavements that are classified as “long life” pavements that are designed to last from 50 to 100 years.

The ability for an epoxy coated dowel bar is dependent on the type of epoxy coating, the thickness of the epoxy, and the application process of the epoxy coating application. This report evaluates the corrosion process of a number of different laboratory specimens including a new generation of epoxy-coated dowel bars.
Load Transfer Findings
All dowel types transferred 80% – 90% of the load across the joints. Medium elliptical steel dowel bars were equally adequate, if not better than standard round dowel bars at
transferring load across the transverse joints.
When used with the American Diamond™ System “strategic reinforcement” design, it helps optimize steel usage in your projects by placing the steel where it is needed most—at the joints. American ST™ Basket Assembly has delivered a significant return on investment for owners, designers, and contractors nationwide.
