1. Flexible Pavement consisting of a subgrade, base
coarse, and asphalt surface coarse to be constructed
in accordance with the followinq (a) thru (e):
a) A six (6) inch thick homogenious subgrade mixed
and stabilized to a Florida Bearing Value (FBS';
of 50 psi minimum and compacted to a minimum of
950 of maximum density (AASHTO T-180).
b) A six (6) inch thick limerock or cemented coquina
base compacted to a 95% maximum density (AASHTO T-
180) or a six (6) inch thick soil -cement base hav-
ing a minimum 7 day compressive strength of 300
psi and compacted to 95% maximum density (using
PASHTO T-180).
c) A D.O.T. approved bituminous prime coat of grade
RC -70 or RC -250 applied from .10 to .35 gallons
per square yard.
d) A compacted 1 -inch thick D.O.T. Type II asphaltic
concrete surface course.
e) Testing of the above flexible pavement construc-
tion shall be by an independent testing laboratory
approved by the County Engineer. The number of
Modified Proctor (AASHTO T-180) tests for subgrade
and/or base work shall be one for each material
type. At least 2 FBV tests or one per 10,000
sauare feet of pavement, whichever is greater, is
required. At least one in place density test for
every 10,000 square feet of pavement using ASTM D-
2167 (Rubber Balloon Method), Sand Cone Method,
ASTM 2922 (Nuclear Method), or other method as
approved by the County Engineer is required for
both subgrade and base course construction. A
minimum of two in place density tests are re-
quired regardless of size of pavement areas.
Soil -cement testing shall be as per Indian River
County Standard Specifications.
2. Rigid (Concrete) Pavement consisting of the follow-
ing (a) and (b) :
a) A six (6) inch thick subgrade stabilized to a
Florida Bearing Value of 50 psi minimum and com-
pacted to a minimum of 95% maximum density using
AASHTO T-180. Testing shall be as for Flexible
Pavement above.
b) For non industrial use, a 4-1/2 inch thick non
reinforced concrete pavement. For industrial
and frequent truck use, a minimum six (6) inch
thick non reinforced concrete pavement. Design
thickness for heavy equipment use shall be in
accordance with the Portland Cement Association
recommendations. Calculations shall be submitted
to the County Engineer with the request for Rigid
Pavement design showing the structural adequacv
of the design and the design life of the project.
All concrete to be 3000 psi in 28 days (AASHTO
T023). All materials, longitudinal, transverse
and construction joint location, material place-
ment, and finishing shall be as recommended by
the Portland Cement Association and the Concrete
Promotional Council of Florida. At least 3 com-
pressive strength cylinder samples shall be taken
for every 10,000 square feet of pavement, or 5
per job; whichever is greater shall apply. Slump
shall be 2 to 4 inches (AASHTO T-119). Compres-
sive strength shall be reported for 7, 14, and
28 days after placement.

3. Paving Stone, block or similar type construction
shall be allowed subject to approvahl by the County
Engineer.
4. Solid Sod and/or grass placed on a stable, load
bearing type subgrade may be allowed for offsite
parking areas subject to infrequent use such as
weekly use characteristic of churches and similar
type functions, for equipment storage areas,
agricultural facilities, and other uses as approved
by the Indian River County Planning and Zoning Com-
mission pursuant to Site Plan Approval. The follow-
ing additional information shall be required as
supporting data accompanying such request:
a) Topographic map of the complete site.
b) Intended use of the site including frequency
of parking and type vehicle.
c) Location of ground water table during the
wettest season of the year.
d) Soil profile to a depth of 6-8' taken at 2
locations minimal.
e) Maintenance program outlined for the parking
area as prepared by the owner.
f) Typical section of the parking lot area.
g) Complete drainage plan for the site.
Each request shall be subject to approval by the
Indian River County Planning and Zoning Commission
pursuant to Site Plan Approval.
5. Driveway Aprons constructed in the County Right-of-
way where a paved County road exists and connects
developments proposed for Site Plan Approval shall
be of the flexible pavement or rigid pavement design,
as specified in (f) 1. and (f) 2. above, and shall
be constructed only after receipt of an Indian River
County Department of Public Works Permit.
•6. All construction within the County Right-of-way and
as referred to in this section shall be to Indian
