College of Engineering JTCP Courses HOT MIX ASPHALT I



The Joint Training and Certification Program (JTCP) has developed a two-part series in Hot Mix Asphalt (HMA) for construction materials lab technicians. To help reduce conflict and delay on construction projects within the state, Caltrans, in partnership with CSULB, has developed a series of joint training and certification programs.

Participants in Hot Mix Asphalt I will receive training and certification in various CTM and AASHTO methods pertaining to HMA testing in the field. This session is focused on representative sampling, sample preparation and aggregate testing use for HMA.

Who Should Attend

This course has been developed for anyone seeking a basic understanding of HMA material field testing. It is intended to focus on areas critical to the successful completion of an asphalt pavement.

Completing the Prerequisite

To complete the prerequisite, students must review provided resource material, view course videos, and pass an assessment quiz. Students must successfully pass the prerequisite course before registering in the Training & Lab course.

Completing the Program

This certificate program consists of completing an online prerequisite, in-class training, and a lab.

The medium of instruction and language of the course will be English.

The timely delivery of transportation improvement projects requires highly skilled, knowledgeable materials sampling and testing technicians. To help reduce conflict and delay on construction projects within the state, the California Department of Transportation (Caltrans), in partnership with CSULB, has developed a joint training and certification program in HMA testing for construction materials lab technicians. This program is the first in a two-part series.

The goal of this program is to ensure that all materials testers — both in the public and private sector — possess equal knowledge and skill in performing lab tests. This will, in turn, help ensure consistent testing, promote quality improvement, and foster positive working relationships between public and private sector employees.

Participants in this program will receive training and certification in various CTM and AASHTO methods pertaining to HMA testing in the field.

Note: In accordance with the IA Manual Amendment, “Testers must attend all training days for the HMA I, HMA II, and/or S&A modules prior to receiving a JTCP Certificate of Training Completion for the module(s) and taking the associated exams.”

  • Determine the aggregate gradation of fine or coarse aggregates
  • Determine the relative proportion of clay-like material in soils or graded aggregates
  • Reduce the aggregate sample to a representative size for testing
  • Determine the total evaporable moisture content of aggregate
  • Determine the moisture content of HMA
  • Determine the percentage of Fracture in Coarse Aggregate
  • Reduce the sample size of HMA and be aware of the safety requirements for running the test
  • Eligible to take HMA II course.

Re-Certification Classes for 2021

  • For the first recertification to any JTCP module (3 years after the initial training), you may opt out of the associated module training days (this excludes the PCC module). To opt out of training, please enroll in the “RECERT” session for the associated module. The “RECERT” sessions will not include any training, and will only consist of written and practical exams. If you elect to enroll in a RECERT session to opt out of the training, you can only be recertified in test methods obtained during your initial JTCP certification. Test methods that you had opted out of during your initial training will not be considered for certification. To opt back into any test method, you will need to enroll in a regular session and complete the associated module training in its entirety. If you have enrolled in a RECERT session and wish to receive the latest Student Handbook, please mark your choice while enrolling in the class. You will need to include a valid mailing or shipping address with your request. For recertification sessions, exams will be administered under the following schedule:
    Written exams: 8 AM to Noon
    Practical exams: 7:30 AM to 3:30 PM, administered on a
    first-come/first-served basis
