Pervious concrete is typically made with natural aggregate
(NA). Recycled aggregate (RA) has rarely been used in pervious
concrete, perhaps due to doubts concerning the resulting strength
of the concrete. In fact, pervious concrete typically must have a
compressive strength below 30 MPa for most applications, so its
permeability, rather than its strength, is emphasized [22]. Quite a
few studies have been performed on no-fines pervious recycled
concrete (NPRC). The available experimental results indicate that
it is workable to use NPRC in base courses, pavement surfaces
and other applications [35].
The results of this study showed that washing can decrease the
amount of chloride in MSWIBA. The TCLP test results for the
washed MSWIBA demonstrate that it can conform to the second
type of MSWIBA quality standard in Taiwan. Washed MSWIBA
can therefore be expected to conform to the chloride content and
TCLP test requirements for typical concrete aggregates. In this
study, the mix proportions, fabrication methods, and engineering
properties of pervious concretes made using washed MSWIBA
were examined to assess the feasibility of washed MSWIBA pervious
concrete, based on its engineering properties. The mix proportions
of washed MSWIBA pervious concrete can be developed
before testing, but reasonable mix proportions should satisfy the
permeability coefficient and compressive strength requirements
associated with practical applications.
