• Mainline pavement lanes, turn lanes, ramps, parking lots, concrete box culverts and retaining wall systems
• A LOT is defined as a single lift of finished embankment not to exceed 500 feet.
• Shoulder-Only areas, bike/shared use paths, and sidewalk areas
• A LOT is defined as 2000 feet or one Day’s Production, whichever is greater.

 Question from Industry – How is Independent
Verification processed.
 Section 120-10 Independent Verification
◦
120-10.1.5 - In addition to the Verification testing, the
Engineer may perform additional Independent Verification
(IV) testing. The Engineer will evaluate and act upon the
IV test results in the same manner as Verification test results.

 QC Sample - 108 pcf
 VT Proctor - 112 pcf
 IV Proctor – 116 pcf
 Resolution Proctor 116 pcf
 What proctor should we use?
 Should they resample the material?

 Where is RAP prohibited?
◦
◦
◦
 Minimize RAP content to avoid possible long term settlement

Reduced Frequency Testing is allowed after 12 passing tests with no Resolution tests in favor of
Verification.

Select test location randomly from one of the two
LOTs under consideration.
Requires Engineer’s permission to place material over untested LOT
Not allowed in shoulder only areas, sidewalks bike/shared use paths. (LOT size)

 Plastic and Metal pipe backfill requires 95% of
Standard Proctor for density.
 Concrete pipe backfill requires 100% of Standard
Proctor.
 Structure backfill requires 100% of Standard proctor regardless of the type of pipe joining the structures.

 Metal pipe requires 95% maximum density
 Structure requires 100% maximum density
 The pipe and structure require separate density tests because of different density requirements.
 This will be clarified in the July 2013 specifications

 Commercial Material - Approved Source (usually Aggregate
Base) 160-2.1
 Requires a Cert from the Mine
 No field sampling or testing required
 Existing Base 160-2.3
 No testing requirements
 IV testing is encouraged and should be performed on any material if there are concerns i.e. bad clay or organic materials …
 Local Materials 160-2.2
 Acceptance requires:
 Source investigation (440 /440A – Projects let after 3/1/11 )
 Sample & test from the roadway for material acceptance
160-3.2.1
(440/440B - Projects let after 3/1/11)

 Meet the requirements of Section 914- 160-2.2 (440/440A)
 Local material may be clay from on-site, material from another construction project, or possibly byproducts from a process.
 The Specifications require testing of the material before it is brought to the roadway and spread.
 Sampling
 Section 914 requires a minimum of 3 organic content test results and one LL/PI test result per source.
 The Engineer should partner with the contractor to investigate the source or stockpile and evaluate each material. (best practice)
 Use one sample card for each source or stratum of material
 Provide a minimum of 3 ½ bags of material for each source

 “ Material ID ” - Enter 440 for projects let prior to March 1, 2011 and 440A if the project is let after March 1, 2011 (This will show in the project job guide schedule)
 “

 Sampling and Testing of Local Materials - Section 160-

• Requires Sampling after spreading and before mixing
• QC 1 per 2 LOTs – VT 1 per 8 LOTs
• “Sample Numbering” - “C001”, “C002”, “C003”, etc and “Q” or “V”
• Collect three pint size bags of material across the roadway (FM 1 – T267)
• Engineer Verification, Resolution and Acceptance - 160-
3.2.1.1
• Stabilizing materials require acceptance before the material is mixed into the Subgrade

Source Investigation (440/440A)
 Evaluate the stockpile as a local material - 160-2.2
 If failing organic content is due to the asphalt content of RAP or
RAP Blended material the department may modify acceptance
(after careful evaluation)
 Modified Acceptance for RAP or RAP Blend (440/440B) http://www.dot.state.fl.us/statematerialsoffice/administration/resources/l ibrary/materialsbulletins/topics/2011/mb02-11.pdf
 Sample for LL/PI before mixing
 Sample and test for Asphalt Content (FM 5-563) (NCAT) after
Mixing
 The upper limit for FM 5-563 in the mixed Subgrade is 4.7%
 Failure may indicate too much Asphalt or the presence of a material with a high organic content

 Sample after spreading and before mixing according to
160-3.2.1 (440/440B)
• Sample Transmittal Card Example:
• “Remarks”
• “RAP Premixing no organic test”
• “ LL/PI test only”
• Sample size is ½ bag

 Sample the material after mixing in 160-3.3 (440/440B)
 Sample size is 1 bag
• Sample Transmittal Card Example
• Use the same sample number as used for LL/PI testing
• “remarks”
• “RAP - Substitute FM 5-563 for FM1-T267”

 120-10.4.1 Standard Proctor Maximum Density Determination: The
Engineer will verify the Quality Control results if the results compare within 4.5 lb/ft 3 of the Independent Verification Verification test result.
Otherwise, the Engineer will take one additional sample of material from the soil type in question. The State Materials Office or an AASHTO accredited laboratory designated by the State Materials Office will perform Resolution testing. The material will be sampled and tested in accordance with AASHTO T-99, Method C. The Engineer will compare the Resolution Test results with the Quality Control test results. If all
Resolution Test results are within 4.5 lb/ft 3 of the corresponding Quality
Control test results, the Engineer will use the Quality Control test results for material acceptance purposes for each LOT with that soil type. If the
Resolution Test result is not within 4.5 lb/ft 3 of the Contractor’s Quality
Control test, the Independent Verification Verification Test result will be used for material acceptance purposes.
