Asphalt Emulsion Receiving Guide
March 2012
North Carolina Department of Transportation Materials and Tests Unit
1. Scope 1.1 The purpose of the NCDOT Asphalt Emulsion Receiving Guide is to aid field
personnel on what to look for with shipments of Asphalt Emulsion. 2. Asphalt Emulsion QC/QA Program Background 2.1 The NC DOT Materials and Tests Unit is required to maintain the Departments Asphalt
Emulsion QC/QA Program.
2.1 The Asphalt Emulsion Quality Control Quality Assurance Program is a comprehensive program designed to verify, assess, and track the quality of asphalt emulsions delivered to North Carolina Department of Transportation projects and maintenance operations. It is also used as a means for qualifying Producers/Suppliers to provide asphalt emulsions in this capacity.
2.2 The Producers are required to submit Quality Control (QC) plans to the Chemical Testing Engineer for review, submit monthly QC reports, and Excel spreadsheets capturing all the on-site and off-site testing done by the Producer to the Chemical Testing Engineer, and participate in Independent Assurance (IA) activities. Once these criteria have been met, the producer will then have all laboratories and technicians certified.
2.3 All laboratories, Producers’ on-site, off-site, or independent, must meet a minimum set of criteria. The laboratories must either be AMRL accredited or NCDOT certified. The NCDOT certification process involves the qualification of all laboratory equipment, protocols, and testing procedures used. The qualification will be under the direction of the Chemical Testing Engineer and his staff.
2.4 In addition, each facility will have a minimum number of NCDOT certified technicians to perform sampling, testing, and record keeping duties during production of material that are used on NCDOT and Federal Aid projects.
2.5 The Materials and Tests Unit is tasked with performing Quality Assurance (QA) verification sampling, testing and record keeping confirming the operation of the Producer’s quality control system and IA assessments and correlations of tests.
2.6 It is the intent of this program that acceptance or rejection of material be based on the total program. Therefore, a comparison of the QC and QA verification and other recent sample data may be used by the NCDOT for acceptance or rejection of a lot of material.
2.7 Participation in this program does not relieve the Producer of the responsibility of complying with all requirements of the NCDOT Standard Specifications for Roads and Structures.
2.8 The latest copy of the program can be found at : http://www.ncdot.gov/doh/operations/materials/pdf/qc_qa_emulsion_ncdot_2008rev1.pdf
3. What to do When Receiving Asphalt Emulsion
3.1 The following is what should be done at a minimum when receiving a sample of asphalt emulsion on the project:
3.1.1 Verify the source of the emulsion. The source of the emulsion must be clearly recorded on the Bill of Lading (BOL). Be careful not to look at the main office address which may also be recorded. The material must come from a terminal on the Departments approved list. Examples of typical BOL’s are shown in Appendix A.
3.1.2 Per the Asphalt emulsion QC/QA program all BOL’s must have the NCDOT assigned batch number recorded. The batch number starts with the approved terminal number. This Batch number will have to be entered into HiCAMS when receiving tack on projects.
3.1.3 The BOL must have the supplier and transporters certifications recorded. The certification state that the material meets the NCDOT requirements and the transport tank was clean and free from contamination.
3.1.4 The net gallons must be recorded and match what is required for the project. For example the contractor may order 5000 gallons and only use 1000 gallons on a particular project. In this case 1000 gallons will need to be entered into HiCAMS for the quantity received.
3.1.5 The approved grade of the material must be recorded on the BOL. An example of the approved list of grades per facility can be found in Appendix B***.
*** Note this list changes periodically. The most up to date list can be found at http://www.ncdot.gov/doh/operations/materials/pdf/aspprodnc.pdf
3.2 If the BOL is lacking any of this information the product should not be received on the project.
