Asphalt QC 2000

• The Adventure Begins.

2
Topics

• Terminology
• Specifications
• Sampling and Testing
• Reporting/CQR
• Who Does What?
• Lube Oil Change
• All in 20 Minutes!

3
In a Nutshell..

• Payment based on Contractors (Quality Control)
  test data that has been verified
• FDOT runs Verification tests at a lesser
  frequency
• Split-sample at plant by project personnel
• Independent sample at District Lab
• Payment is based on density on the roadway and
  air voids, asphalt content and gradation at the
  plant
• Percent Within Limits (PWL) larger quantities
• Pay Table smaller quantities
• Big Change!

4
General Details Include.

• Initial lot size mandatory 2000 tons
• Following lots may be 2000 or 4000 tons
• Contractors option w/Engineers Approval
• Deleted Initial Production Test Strip No
  Pause
• Typical lot size 4000 tons
• English and Metric the same
• 4 sublots per lot (1000 tons each)
• Plant lot and roadway lots are the same
• All sampling performed by the Contractor
• FDOT establishes when to sample
• Several options available

5
Whos on First?
6
General Overview - Plant

• Engineer (VT) directs Contractor (QC) when to
  sample
• Random basis generated by Excel Spreadsheet
• 1/sublot (1/1000 tons or 1/500 tons)
• QC splits out and boxes up Verification and
  Resolution Samples
• Tests include
• Asphalt Content (FM 5-563 only)
• Gradation (FM 1-T 030)
• Air Voids (AASHTO TP-4 FM 1-T 209)

7
Verification - Plant

• Performed by Agency - FDOT or Consultant (CTQP
  Plant Level I)
• Tests run at plant
• Split-sample randomly selected 1/lot (1/4000
  tons or 1/2000 tons)
• Same tests as QC
• Precision statement comparison with QC results
• Gmm, Gmb, Pb, P-200, P-8

8
Between-Laboratory Precision Values
9
Verification Plant (Contd)

• If all results compare
• Accept material
• Payment based on Contractors QC results
• If the results dont compare
• VT tests remaining sublot samples for property
  (or properties) in question.
• If only initial unfavorable comparison accept
  material and pay based on QC results
• If two or more unfavorable Resolution
• Samples sent to District Lab

10
Independent Verification - Plant

• District Materials takes two samples per 12,000
  tons
• Tested at District Lab
• Same tests as QC
• Results have to meet requirements of Master
  Production Range
• Go or no go.

Quality Control Sampling and Testing Roadway

• Core locations identified by VT
• Tonnage basis
• Contractor cuts five cores per sublot
• Example 1000 ton sublot, 12 ft wide lane
• 150 lb/sy 1 core/2000 feet
• 200 lb/sy 1 core/1500 feet
• 250 lb/sy 1 core/1200 feet
• 300 lb/sy 1 core/1000 feet
• QC tests cores per FM 1-T 166
• Retains cores for Verification/Resolution

13
Verification - Roadway

• Tests performed by Verification Technician
• Tests run at plant
• Same-cores
• VT tests all five cores from a randomly selected
  sublot
• Same test as QC
• Precision statement comparison with QC results
• Gmb 0.022
• Compare favorably Pay based on QC results
• If not similar to plant Resolution

14
Independent Verification Roadway

• District Materials directs Contractor to take
  five additional cores from same sublot as plant
  IV sample
• Results have to meet requirements of Master
  Production Range
• Average density must meet minimum
• Go or no go.

15
Compensation

• If two or less sublots use Small Quantity Pay
  Table based on average deviations from target
• If three or more sublots use the estimated
  Percent Within Limits (PWL) for the lot, based on
  the following characteristics
• Density
• Air Voids
• AC Content
• P-200
• P-8

16
Compensation (Contd)

• Pay factor for each characteristic is determined
• Composite Pay factor is based on
• 35 Density
• 25 Air Voids
• 25 AC Content
• 10 P-200
• 5 P-8
• All calculations by Excel spreadsheet
• Not by hand!

17
Reporting

• Contractor reports all QC test results,
  quantities, etc.
• Daily Asphalt Plant Quality Control Report
• Daily Asphalt Roadway Quality Control Report
• Inputs into CQR
• CEI reports all Verification test results and
  Verification activities
• Verify mix spread rate, tack spread rate, mix
  temperature, etc.
• Asphalt Plant Verification Report
• Asphalt Roadway Verification Report
• Inputs into CQR
• Forms currently under development
• CQR access through District Construction Office

Industry Perspective QC 2000 Asphalt
Specifications

• Jim Warren
• Asphalt Contractors Association of Florida, Inc.

28
Contractor perspectives

• Old
• What good will this do?
• Oh No!, Not another new specification!
• Lets go back to S-1
• Now
• Its no so bad I see some positives.
• Were trained, were equipped Lets Roll!
• Opportunities

29
What's different from the old system?

• Same Superpave Mix as before
• Still going to test it the same way no new
  tests
• More QC responsibilities than before
• Must change focus from average to uniformity
  about average (big change)
• Its still Hot, Black, and Sticky.

30
Whats in it for the contractor?

• More flexibility to run your operation.
• More responsibility and authority to make sure
  the job is done right.
• Less reliance of others for decisions of when to
  pave, adjustments to make, etc.
• Less rework, fewer call-backs, less wasted
  profits and opportunity costs.
• QC tests finally mean something.
• Finally, a payback for investing in QC personnel
  and equipment.
• Mo money (if you know what youre doing).

31
Whats in it for the Industry?

• - Identify whats different under these new
  specifications compared to current
  specifications,
• - Understand the respective roles and duties of
  the parties involved, and
• - Understand the acceptance process.
