Hot Mix Asphalt Plant NYSDOT Approved Plant
Annual Inspection 90 Day Scale Checks Up-to-Date
Mix Designs NYSDOT Regional Materials assigns production status to all Superpave mix designs that
have been successfully plant verified. The owner is encouraged to review all Superpave mix designs and make their own
determination on acceptability.
For all Marshall Mixes, a mix design must be submitted for approval by the owner.
Plant Inspection Required for daily Superpave production >500 TON.
Plant may certify quantities of less than 500 TON.
NYSDOT Standard Specifications §401-3.03 requires 3:00 PM notification the day before production to arrange for inspection. Contractor must give notification to plant prior to 3:00 PM to ensure scheduling can be
accommodated.
Plant Inspection Quality Assurance/Quality Control Certification Program (Alfred
Certification) Inspector must possess current certification. Recertification is required every 5 years.
Superpave (NYSDOT Standard Specifications §402) Inspection progressed as per NYSDOT Materials Procedure 401.
Daily production for each mix is broken into 1000 TON Sublots. Independent QC and QA aggregate and hot mix asphalt samples are taken within each
Sublot. Samples are tested for Gradation, Bulk Specific Gravity, Maximum Specific Gravity, and %
Air Voids. A Plant Production Quality Adjustment Factor (QAF) is calculated based upon the results of
these tests. The inspector also completes all required paperwork, records in the Hot Mix Asphalt Daily
Diary pertinent/required information pertaining to the day’s production, and prepares the BR 343 – Daily Hot Mix Asphalt Authorized Shipments.
Plant Inspection Marshall Mix (NYSDOT Standard Specifications §403)
Section 403-3 Construction Details assigns responsibility to the Contractor for production Quality Control. Unless otherwise specified, a Quality Control Technician is not required to be present
during production. Typically the Quality Control Technician will monitor and verify mix production via
automation.
Owners are encouraged to perform Quality Assurance Testing to ensure the quality of the hot mix asphalt being produced. Asphalt content verified via automation.

Mix Designs Annually or when updates are necessary, Regional Materials provides the producer with mix
designs for all NYSDOT concrete classes (A, D, J, H, etc.).
For all non-NYSDOT mixes, a mix design must be submitted for approval by the owner.
Plant Inspection Required for all concrete production of 25+ CY.
Plant may certify quantities of less than 25 CY.
NYSDOT Standard Specifications §501-3.03 requires 3:00 PM notification the day before production to arrange for inspection. Contractor must give notification to plant prior to 3:00 PM to ensure scheduling can be accommodated.
Plant Inspection NYSDOT Concrete Batch Plant Inspector Certification Program
Inspector must possess current certification. Recertification is required every 5 years.
Inspection progressed as per Materials Method 9.1 - Plant Inspection of Portland Cement Concrete.
Each production day, aggregates are sampled and tested for gradation and moisture content.
For HP concrete, moisture corrections are calculated to determine the required hold back water.
Cement, flyash, and microsilica samples are obtained and sent for testing, as appropriate. Frequent sampling is encouraged to ensure the quality of the materials incorporated in the batch.
Verify the correct mix design is being batched under automation, in spec, using approved materials, and being transported in an approved truck.
The inspector records in the Concrete Daily Diary all pertinent/required information pertaining to the day’s production and prepares the BR 316 – Daily Concrete Batch Plant Report.
Field Inspection Certifications.
ACI Concrete Field Testing Technician Grade I NYSDOT Field Testing Technician Program NICET Level II Construction Materials Testing Technician
Inspection as per Materials Method 9.2 - Field Inspection of Portland Cement Concrete.
Slump/Air Tests at a minimum of every 50 CY.
Slump/Air/Temperature/6” x 12” Concrete Cylinders at a minimum of every 200 CY. A minimum of 2-28 Day Cylinders must be cast for each structural element. No more than 8 Cylinders should be cast for any structural element.
All samples must not be obtained from the first or last 10% of the load. Cylinder samples must come from the middle third of the load.
Additional slump/air testing and fabrication of cylinders may be necessary, if mix quality problems are encountered.
To limit the potential risk of out of spec material being incorporated into the work, placement should be halted while the concrete is being tested.
Field Inspection If the material begins to test marginally,
Inform your Contractor. The contractor should then contact the plant to request corrective action. Increase testing frequency until you have confidence the material has improved. Communication, communication, communication!
If you encounter out of spec test results, Inform your Contractor. Resample and Retest. If the retest fails, reject the load. Increase testing frequency until you have confidence the material quality has improved. Out of Spec Material CANNOT be accepted!
Cylinder Curing NYSDOT Standard Specification Table 555-4
Notes 1 & 3 require “Early Open” cylinders to be cured in the same manner as the structural element they represent.
Cylinders should also be protected from freezing or excessive heat (baking in the sun).
