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.
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.

Low Volume Roads
Doweled joints provide high and constant LTE, controls faulting
There are many advantages for the use of concrete on low volume roads. The technical data provided in this section discussed the two most important aspects of concrete pavement design; slab thickness and jointing.
Jointed Plain Concrete Pavements
This guide provides a summary of the factors and design theories that should be considered when designing dowel load transfer systems for concrete pavement systems (including dowel basket design and fabrication) and presents recommendations for widespread adoption (i.e., standardization). Development of the guide was sponsored by the National Concrete Consortium with the goal of helping practitioners develop and implement dowel load transfer designs based on knowledge about current research and best practices.
Scientific and technical information recorded and presented
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.
