3.5. PROPERTIES AND INSTALLATION OF PERMEABLE PROCESSED STONE:
3.5.1. Delivery Moisture Content
3.5.1 .l. Processed stone must contain 90% to 1 10% of the optimum moisture content to ensure
that fines do not migrate in transit or during placement and to facilitate proper
compaction. This is critical. The contractor shall ensure that aggregate leaving the
source plant meet this requirement. The contractor is required to apply water to the
processed stone on site to attain and maintain this minimum moisture content.
3.5.2. Handling & Placement
3.5.2.1. Prior to aggregate placement, remove any excess or contaminated backfill from the
drainage trenches.
3.5.2.2. Should any separation of the materials occur, during any stage of the spreading or
stockpiling, the Contractor must immediately remove and dispose of segregated material
and correct or change handling procedures to prevent any further separation. Double
handling of materials is not allowed.
3.5.2.3. The Contractor must utilize laser controlled equipment for the grading of the processed
stone to ensure accuracy in the grade tolerances of +Ow' to -114" in ten feet (10').
3.5.2.4. Install processed stone base, from sideline toward center-line, parallel to the composite
drain network, to the lines and grades shown on the drawings. Under no circumstance
shall the material be pushed more than 30' from the point of discharge.
3.5.2.5. The Contractor shall shape the complete surface of the processed stone to receive the
elastic layer component and continue until the deviation from the required elevation does
not exceed a maximum deviation from grade of '+O" to -114" in ten feet (IO'), when
measured in any direction using a 10' straight-edge.
3.5.2.6. Each'layer must be spread uniformly with equipment that will not cause perceptible
separation in gradation (segregation of the aggregates), preferably a self-propelled
paving machine or small laser controlled low ground pressure (LPG) dozer. Use a laser
guided road grader properly operated to provide a more uniform surface.
3.5.3. Compaction and Planarity
3.5.3.1. The processed stone shall be compacted to a minimum density of not less than 95% of
maximum density as determined by ASTM D698 and measured using a nuclear method.
Aviara Community Park - Community Park
City Of Carlsbad
NTD # 2000-0247-03
SYNTHETIC TURF - SUBSURFACE CONSTRUCTION
' 02792 - 6
3.5.3.2. Proof roll wherever possible and mark "soft spots" for additional compaction or
correction. Use static tandem drum-type roller of not less than five (5) tons weight.
Proof rolling operations must be preformed in the presence of a Geotechnical Engineer.
3.5.3.3. The finished surface shall not deviate (tolerance-to-grade) from designated compacted
grade. This means that the surface shall not deviate more than 114'' in 10' (any
direction) when placed under a 10 foot straight edge. This tolerance is required over the
entire field.
3.5.3.4. Areas that deviate shall be marked with spray paint and corrected with 3/8"(minus)
limestone or granite chips and rolled tight to achieve proper density. Such remedial
actions shall be done by hand and rechecked by means of test procedures described
above. This procedure shall be used to correct any small areas that show segregation.
3.5.4. Testing
3.5.4.1. The surface of the processed stone course shall be well drained at all times.
No standing water shall be permitted at any time. The permeability of the aggregate
shall be checked per Din 8035 Part 7 (preferred), ASTM 2434 (constant head), or
ASTM D3385 (double-ring) testing methods. Test samples shall be taken (at a
minimum of) one sample per every 5,000 square feet or as otherwise directed by the
Owner's Representative.
3.5.4.2. All test results will be logged and documented by the Owner's Technical Representative
or Geotechnical Engineer. If at any time the processed stone base does not meet
specifications, it shall be the Contractor's responsibility to restore, at his expense, the
processed stone base to the required grade, cross-section and density.
3.5.4.3. After the contractor has independently confirmed compliance with all the above
tolerances (planarity and elevation verified by a licensed surveyor and compaction,
gradation, & permeability verified by Geotechnical Engineer), he shall notify the
appropriate party and schedule a final inspection for approval. The contractor shall make
available an orbital laser system to the Owner for the inspection process. A topo shall
be taken on a 10' grid and submitted to Owner prior to synthetic turf or padding
installation. All survey costs associated with insuring compliance with all of the above
tolerances shall be performed by the Contractor at no additional cost to the owner and
shall be provided as necessary to insure such compliance subject to the sole discretion
of the Engineer.
3.5.4.4. A survey shall be provided by a licensed surveyor with a minimum of 1500 survey points.
Contractor must provide all project surveys. No additional compensation shall be
granted for survey.
