The Interlocking Concrete Pavement
Institute assured that non-permeable pav-
ers are going strong, stating that of the ap-
proximate 460 million total square feet of
pavers sold in the U.S. in 2014, only about
25 to 30 million square feet were for permeable interlocking concrete
pavement systems.
Another healthy sign:

The standard that ICPI is developing (expecting ASTM approval
this year), defines a slab as a unit with a length to thickness ratio
greater than 4, a minimum thickness greater than 30 mm and a max-
imum length and width of 48" x 48". Icpi.org
(courtesy of IcPI) slab stats
• Life span is at least 40 years (if designed and
installed correctly)
• Can be constructed with slightly widened joints
filled with permeable aggregates over open-
graded (permeable) aggregate bedding, base
and sub-base
• Can be made with concrete that is stronger
and more durable than cast-in-place con-
crete
• Can be removed and reinstated for utility or base
repairs without destroying and having to replace
the concrete
• Can have a visually calming effect
• Has limited use in vehicular applications

With all the buzz about, and love being given to, permeable
and pervious pavement systems these days, LC/DBM decided
to check on the health of their non-permeable cousins.
