Asphalt Plant Level 2 Training Course

The Asphalt Plant Level 2 Training Course is designed to provide advanced training for technicians and Department personnel involved in asphalt plant operations and quality control processes. This course focuses on the procedures and technical knowledge required to maintain consistency, uniformity, and compliance with Department specifications in asphalt mix production.

The Asphalt Plant Level 2 Training Course is delivered over three days and includes detailed instruction on asphalt plant operations, quality control procedures, and statistical analysis used in asphalt production. Participants learn how to evaluate asphalt mix materials and understand the full production process, from the properties of component materials to the final transportation of the asphalt mixture to the roadway.

Course Structure and Duration

The Asphalt Plant Level 2 Training Course is a three-day program that includes classroom instruction and a written examination conducted during the second half of the third day. The written examination lasts approximately four hours and consists of multiple-choice questions designed to evaluate the participant’s understanding of asphalt plant operations and quality control procedures.

Throughout the training, the course emphasizes the importance of maintaining uniformity and consistency in asphalt mix production. Participants learn about the properties of asphalt materials and how these materials are blended, heated, dried, and mixed to produce a high-quality asphalt mixture that meets construction specifications.

Asphalt Mix Production and Material Control

A major focus of the Asphalt Plant Level 2 Training Course is understanding how asphalt materials behave during production and how technicians can maintain consistent mix quality. The course reviews the importance of properly managing component materials, including aggregates and asphalt binders, to ensure that the final mixture meets required performance standards.

Participants learn about stockpiling aggregates and properly loading materials into cold feed bins, which plays a critical role in maintaining accurate material proportions during asphalt production. Proper blending techniques are also discussed, including how adjustments to the blend may be required based on test results and quality control data.

By understanding these processes, technicians can help ensure that asphalt mixtures remain consistent throughout the production cycle and meet the specifications required for roadway construction.

Quality Control and Statistical Analysis

Another important component of the Asphalt Plant Level 2 Training Course is the review of Department specifications used for the acceptance of asphalt mix at the plant. The course introduces the statistical approach behind these specifications, helping technicians understand how production data is analyzed to determine whether asphalt materials meet required standards.

Participants also learn how to interpret quality control charts, which are used to monitor asphalt plant operations and identify potential variations in production. Understanding these charts allows technicians to detect problems early and make operational adjustments before quality issues affect the final asphalt pavement.

The course also covers the theory and use of random numbers for obtaining samples, a key method used to ensure unbiased testing during quality control procedures.

Asphalt Plant Calibration and Inspection

Proper calibration and inspection of asphalt plant equipment are essential for producing high-quality asphalt mixtures. The Asphalt Plant Level 2 Training Course provides instruction on plant calibration procedures, inspection methods, and the correct operation of asphalt production equipment.

Participants learn about proper loading procedures, scale checks, and mixture weighing, which help ensure that materials are measured accurately during production. These procedures are critical for maintaining correct material proportions and ensuring that asphalt mixtures meet required specifications.

The training emphasizes the importance of maintaining consistent materials, proportions, and temperatures throughout the production process. Proper quality control practices help ensure that asphalt pavement performs well over time and meets safety and durability requirements.

Course Prerequisites

Before attending the Asphalt Plant Level 2 Training Course, trainees employed by the Department must meet specific prerequisites. Participants must have successfully completed the Department Asphalt Concrete Plant Inspection Self-Study Examination (CQC version) and must also have at least 90 days of experience in asphalt plant operations.

These prerequisites ensure that participants already have a basic understanding of asphalt plant procedures before enrolling in this advanced training course.

Written Examination

At the conclusion of the course, participants must complete a four-hour open book written examination consisting of multiple-choice questions. The examination is electronically graded by the CTQP Administrator, and a minimum passing score of 70 percent is required.

Participants should allow approximately two weeks for grading and posting of examination results after completing the test.

Although attending the Asphalt Plant Level 2 Training Course is strongly encouraged to gain a full understanding of the material, course attendance is not strictly required for qualification.

Completing the Asphalt Plant Level 2 Training Course helps technicians develop the advanced knowledge needed to monitor asphalt plant production, interpret quality control data, and ensure compliance with Department specifications. By understanding plant calibration, statistical analysis, and proper material handling procedures, participants can contribute to the production of consistent, high-quality asphalt mixtures used in roadway construction projects.
