Attached for your use are two copies of a technical paper on the benefits of
using dowel bars in PCC pavements. This paper suggests that dowel bars she;::
be used on all pavements, except possibly those with low truck volumes.
paper also points out the need for proper installation if the benefits of the
dowels are to be realized. Many States are experiencing premature deterioration
of their undoweled PCC pavements. In these cases, we encourage the field offices
to work with the States in evaluating the merits of dowel bars.
We suggest that a copy of this paper be forwarded to each division office.
We appreciate the efforts of the regional offices in reviewing the draft of
this paper. If you have any questions concerning this paper, or wish to offer
information relating to recent field experience with the installation of dowel
bars, please contact Mr. David Law at FTS 366-1341.
