The American Association of' State Highway and Transportation Officials (AASHTO)
Subcommittee on Construction is presently preparing a new edition of the AASHTO
'Guide Specifications for Highway Construction.m The AASHTO decided to survey
the States' current practices on rigid pavement joints to help rewrite
Section 514 titled "3oints..' We agreed to assist them by preparing and then
summarizing that survey (spacing, skew, dowel cages, epoxy coated bars, filler
material, etc.). Attached for your information is a sumary of the survey
results. Please note-there were five State highway agencies that did not
respond to the survey.
The survey is intended to cover the States' current practices and recent
performances with rigjd pa~ccacnt Joints. It may not ntcessarfly reflect
each States's current standard tpeciflcations. However, we believe the
sumnary contqins worthuhfle information that can be used as a reference
tool for highway engineers.
We will appreciate your forwarding copies to the division offices. Copies of
the survey have already been sent to the State highway agencies by the AASHTO
Subcomnittee on Constructton. Any questions or comnents may be dtrected to
Mr. Don Voelker of my staff at FTS 366-1333;
