Pervious

pavement

systems

are

now

being

recognized

as

a

best

management

practice

by

the

Environmental

Protection

Agency

and

the

state

of

Florida.

The

pervious

concrete

system

is

designed

to

have

enhanced

pore

sizes

in

the

surface

layer

compared

to

conventional

pavement

types,

encouraging

flow

of

water

through

the

material.

This

research

project

investigated

the

infiltration

rates,

rejuvenation

techniques,

sustainable

storage

of

the

components

and

complete

systems,

water

quality,

and

the

strength

properties

of

pervious

concrete

pavements.

The

work

was

conducted

at

the

field

labs

of

the

Stormwater

Management

Academy

at

UCF.

The

Flexipave

systems

indicate

that

they

perform

as

intended

unless

subjected

to

excessive

sediment

loads

or

high

ground

water

table.

Maintenance

by

the

use

of

a

vacuum

sweeper

truck

was

successful

in

removing

surface

sediments

but

is

ineffective

at

removal

of

deep

penetrating

sediments.

However,

it

is

much

harder

to

clog

these

in

the

first

place

due

to

a

more

open

surface

nature.

The

reduction

in

rates

is

only

observed

when

significant

amounts

of

sediments

enter

the

system

and

migrate

into

deeper

locations.

The

sustainable

storage

of

the

entire

system

was

found

to

be

about

10%.

This

pervious

pavement

system

is

recommended

as

an

effective

infiltration

BMP

that

will

perform

well

throughout

its

service

life.

The

average

compressive

strength

is

about

115

psi

and

the

average

modulus

of

rupture

is

around

170

psi.
