This course is designed to instruct technicians and engineers on appropriate methods and procedures used to make process control adjustments and for solving mix problems.  


CONCRETE CERTIFICATION SCHOOLS            
This entry-level training allows the student to become ACI and NCDOT certified. This course will include a fundamental understanding of NCDOT specifications, basic concepts and components of concrete, and how to correctly complete NCDOT forms relating to concrete sampling.  In addition, the student will be trained and tested on all field performance tests which include; calibration of “Type B” air pressure meter, measurement of air content in concrete using the “Type B” air pressure meter, temperature specifications, sampling specifications, making and curing of test specimens, air content using the volumetric method (roll-o-meter), unit weight, Chace Indicator, and slump test.  To be certified, each student must pass all field performance tests, the NCDOT written exam, and the ACI written exam.  ALL STUDENTS WILL BE REQUIRED TO COMPLETE ALL THREE PARTS-NO EXCEPTIONS.
This class option administers the written and performance tests required for NCDOT Concrete Field Technician Certification.  The student registers for a regular class choosing Self Study. The student is issued the study materials ahead of time for preparation of the exam. 3   Students are notified in confirmation memo to show up last day of class for testing only. The exams include the ACI Written Test, the ACI Performance Test, and the NCDOT Written Test.  The Chace Indicator Test is conducted during the ACI Performance Test.            
Individuals who are currently ACI Concrete Field Testing –Grade 1 certified and seek NCDOT certification only will participate in this class option and be exempted from the ACI written exam and the field performance tests portions (except for the Chace Indicator Test).  Students are notified after registering for class by confirmation memo to show up the first day of class for review of NCDOT and testing.              
Individuals failing the NCDOT written exam are allowed to retake the exam within one year of the original school.  NCDOT Written Retest is selected as the option for class-after registering for class a confirmation memo instructs student to show up last day of class for testing only.           
This class option is selected for those that have failed the ACI Written Test but have passed the NCDOT part.  After registering for class, a confirmation memo will be sent instructing student to show up on last day of class for retest only.
This class option is selected for those that have failed the ACI Performance Test but have passed the NCDOT part and ACI Written test. A confirmation memo will be sent to those instructing student to show up on last day of class for testing only.             
This two-day school is for the individual whose job responsibilities pertain to activity at a concrete batch plant.  Subjects covered include: NCDOT specifications, plant operations, admixtures used in concrete and their characteristics, moisture determinations, and batch weight adjustments.  This school will provide a NCDOT Batch certification only after a separate on-site evaluation is successfully completed.  The evaluation will be administered to the students that successfully complete the classroom portion.  The purpose of the evaluation is to ensure the student’s ability to actually batch concrete according to the NCDOT specifications.  Students who have never been NCDOT Certified Batch Technicians have a prerequisite of being a Certified Concrete Field Technician.  Training is conducted in a classroom setting where a basic understanding of batching operations is needed and mathematical formulas and calculations are used routinely.  This certification is required of all technicians batching concrete for NCDOT or a NCDOT- related project.             
This three day advanced school instructs an in-depth, step-by-step procedure to produce the following:  ACI concrete mix designs, design variations, weight – volume relationships, and aggregate gradation.  Additional subjects include: admixtures and their uses in concrete, use of Portland cement, use of fly ash in concrete, and placing and curing of concrete.  Training is conducted entirely in a classroom setting where mathematical formulas and calculations are used extensively.  Prerequisite for the school is a Concrete Batch Certification.           
This two day school is for the individual whose job responsibilities include concrete paving placement, sampling and testing.  Subjects covered include: NCDOT specifications, MIT SCAN, maturity and joint scoring.  Prerequisite for the school is completion of the requirements for Certified Concrete Field Technician.  Batchers of pavement concrete must also be Certified Concrete Batch Technicians.  Once the classroom portion of the Concrete Pavement Technician School is successfully completed, all personnel involved in the testing and acceptance of concrete pavement must complete field tests conducted by the Materials and Tests representative at an approved concrete laboratory site.  All personnel in the operation, recording, or interpretation of data relating to the Rainhart Profilograph (Model No. 860) must demonstrate operation and data interpretation on an approved jobsite in the presence of designated personnel.

Lab Testing ServicesMM-03-04Approved
  

The Materials and Tests Unit's Structural Materials and Services Group strives to provide quality services to the Department of Transportation, other state agencies, municipalities and producers/suppliers that conduct business with the state of North Carolina in the areas of testing (chemical, environmental, and physical), inspection (including coatings, corrosion , and others), specifications, technical expertise, innovation and research. These functions ensure that the highest quality materials and products as well as installation and application techniques are used in the construction of North Carolina's roads and structures.

The group is divided into the Structural Materials Laboratory Section and the Structural Material Services Section. Each of these Sections are further divided into sub-sections.

Structural Materials Laboratory Section

The Physical Testing Sub-section is responsible for determining and evaluating the physical quality of various materials used on the State Highway System. The Sub-section receives samples for testing from field inspectors, contractors, manufacturers and producers. The Sub-section also reviews and assigns all concrete mix designs used throughout the State in structures and pavement.

The Chemistry Testing Sub-section is responsible for determining and evaluating the Chemistry of various materials used on the State Highway System. The Sub-section receives samples for testing from field inspectors, contractors, manufacturers, producers, and other labs within the Unit. 

Structural Materials Services Section

The Structural Materials Services Section is divided into two subsections – Metals and Prestressed Concrete. Personnel from these subsections travel to various fabrication and production plants, both in North Carolina and throughout the Eastern U.S.

The Metals Subsection is responsible for the shop inspection of structural steel, epoxy coated rebar, metal bridge rails and joints, and gray iron castings. This subsection is also responsible for the qualification of welding operators and welding electrodes and advises the Resident Engineer’s personnel on welding issues that arise on the project. In addition, the Metals Subsection is responsible for inspecting the fabrication of signs, sign supports, and high mast standards. The Sign Inspectors also perform both daytime and nighttime inspections of these items with the Resident Engineer’s inspectors once they are installed on the project.

The Prestressed Concrete Subsection is responsible for the plant inspection of all prestressed concrete products used by the Department. Prestressed Concrete Inspectors perform 100% inspection of the production process – from tensioning, and set up of the beds to de-tensioning and final approval of the completed product.

The Field Operations area is responsible for sampling and testing the various materials used in the construction and maintenance of our highway system and for conducting Technician Assessments. In order to accomplish this tremendous task, this section is divided into four geographical regions.   Each region is managed by an Area Materials Engineer and consists of three to four Sections that each correspond to a NCDOT Division.  Each section is comprised of a Section Materials Specialist and one or two Materials Technicians.

Each section has the responsibility of inspecting materials produced at all the quarries, sand pits, ready-mixed concrete plants, corrugated metal pipe plants, corrugated plastic pipe plants, concrete pipe plants, precast concrete plants, seed companies, and other specialty plants and manufacturers in their area. Additionally, these inspectors travel to various production facilities throughout the eastern and mid-western United States. 

The Field Operations area is also responsible for conducting Concrete Technician Certification classes throughout the State.​

​The Data Collection and Investigations Section is a component of the Field Operations Sub-Unit of the Materials and Tests Unit.  It is responsible for performing research into new materials submitted for use in our highway system.  This consists of identifying the need, preparing a work plan, initiating research, performing, and monitoring the research, analyzing the results and implementing any new or modified procedures or specifications as a result of the research.  Additionally, this Section is responsible for initiating engineering investigations to determine the reasons for poorly performing materials or manufactured products which fail to perform as designed and develop specifications or procedures to revise or correct the problem. The Data Collection and Investigations Section is also responsible for coordinating the Materials and Tests Unit's involvement with contract research with FHWA, ITRE, Universities and other Units within the Department of Transportation.  

Additionally, it is responsible for performing a variety of field inspections and testing; this includes, but not limited to, video pipe inspections, drilled shaft inspections, MIT scans, latex modified concrete pull-out testing, concrete and bituminous coring, and concrete maturity. Data Collection collects roughness (IRI) and rutting data on the secondary (SR) system, and skid friction data on the primary network (Interstate, US and NC routes). Also conducts training and QC/QA operations for the NCDOT Pavement Condition Survey.
