This letter is regarding the “reduced vibration zones in public sidewalks” issue
as it pertains to segmented pavements.
First, I would like to express my thanks to the Access Board for removing
unwarranted restrictions of unit payers. Research conducted by the University of
Pittsburgh, Department of Rehabilitation Science & Technology, as well as that
by a consortium of the Brick Industry Association, the Interlocking Concrete
Pavement Institute and the National Concrete Masonry Association, has
conclusively proven that segmental pavements do not cause more harmful vibration
than other common pavement types. The research concluded that the clay payers
produced less vibration that the poured concrete control, and required no
additional work to traverse.
Second, I would strongly encourage the Board retain Section 1103 as currently
drafted, withholding any restrictions on the use of segmental pavements within
the pedestrian access route and reduced vibration zone.
In closing, let me express my thanks for taking the time to consider my
concerns.
Sincerely,
Keith Heavener
President
