The general dowel equations in Table 1 apply to Property estimates of dowel bearing calculation of lateral values for single dowel-typeresistance and dowel moment resistance should be fastener connections between wood-based based on the limit state being investigated.

To evaluate the effects of dowel bar alignment, a joint-by-joint evaluation concept called the Joint Score (JS) has been developed (details of the JS system are available in ACPA’s SR999P). The JS, a measure of the combined effects of all misaligned dowel bars at a given joint, represents the potential for locking of the single joint under evaluation.

Too short a dowel bar will restrict the loading transfer capability across the joint, which will potentially cause the uneven settlement between slabs and even rehabilitation, while too long a dowel bar will be a waste of resource. Since early 2000, the price of steel.
