American Highway’s operational and sales team are recognized in the infrastructure industry the individuals that have spent the past 30+ years working with federal and state authorities to help develop the standards and manufacturing capabilities for load transfer in concrete pavements. We have proven the ability to innovate our products so that concrete paving is cost-competitive and longer life to asphalt pavements.
Load transfer is the ability of a joint or crack in concrete pavement to transfer load from one slab to the next through shear action. Load transfer influences the magnitude of deflections in the slabs under loading and the distribution of stresses in the slab.
Welded dowel assemblies are steel dowel bars arranged in a frame spaced at proper intervals and at the midpoint of the pavement thickness. This device can address all of the problems inherent in adequately transferring the load from one pavement section to the next.
Dowel bars are short steel bars that provide a mechanical connection between slabs without restricting horizontal joint movement. They increase load transfer efficiency and reduce joint deflection and stress in the approach and leave slabs.
Tie bars are deformed rebars or connectors used for holding faces of rigid slabs in contact to maintain aggregate interlock. Tie bars are not load transferring device.
Similar to welded dowel assemblies, a tie bar assembly (TBB) are simple truss structures used to hold tie bars at the appropriate height before PCC placement.
American Highway pioneers innovation, striving to forge a new class of affordable, high-performance products, including our Armour Coat ™ dowel bars and baskets, dowel basket alignment stripe, and new dowel shapes such as the elliptical dowel or hollow tube.
A coating system on dowels that is comprised of a flexible abrasion-resistant overcoat (ARO), that is a thermosetting epoxy powder coating engineered to be applied over a fusion-bonded epoxy corrosion resistant undercoating. This serves as an alternative to the commonly used steel and epoxy-coated dowels and is specified in long-life (40 to 100 year) pavement designs.
The main advantage of elliptical dowels over traditional round dowels is in the increased bearing area and the resulting reduction in bearing stress on the concrete.
Marking the mid-point on the dowel bars at the manufacturing plant adds a visual guide for placing the basket on the center of the transverse joints on grade. This alignment guide will also facilitate inspection in the field.
American Highway is Industry 4.0 We use automation and data-driven decision-making to improve the safety, efficiency, and sustainability of our products and services. We are committed to providing our customers with the best possible products and services, and we are always looking for new ways to innovate.
