Bituminous Mixtures Technician In-Training | Two Positions

Transportation Technician

The Washington State Department of Transportation (WSDOT) is seeking two Transportation Technicians to support the Bituminous Section within the Bituminous Mixtures Laboratory, providing critical services for statewide capital construction projects and local jurisdictions through bituminous mixture design verification, conformance, and forensic testing.

In these roles, you will perform complex laboratory testing, prepare and analyze test samples, and ensure accurate reduction and documentation of data, while also assisting the Bituminous Testing Engineer with equipment calibration, maintenance, and recordkeeping to maintain compliance with established standards. Strong candidates will demonstrate technical proficiency in materials testing, data accuracy, familiarity with laboratory equipment and calibration processes, and the ability to interpret and document complex test results.

These positions perform materials testing duties in a laboratory environment which may include exposure to chemicals, elevated temperatures, working with materials exceeding 325 degrees F, and working with various chemicals. This position requires ability to stand for long periods of time, walk long distances and work under time constraints using timers, stopwatches, etc.

Among the varied range of responsibilities held within these roles, the Bituminous Mixtures Technicians will:

• Be responsible for performing complex bituminous mixture testing.
• Prepare Qualified Product List (QPL) asphalt mixtures which incorporate volumetric design of asphalt mixtures as well as all other asphalt mixture design types as requested.
• Perform all test methods assigned to the Bituminous Mixtures Laboratory.
• Assist the Bituminous Testing Engineer in maintaining equipment calibrations, verifications, maintenance, and associated records.
• Be responsible for testing AASHTO re:source Proficiency Samples and participation in AASHTO re:source onsite inspections.
• Operate a personal computer using a variety of software programs.
• Troubleshoot and run diagnostic tests, input data into several specialized software programs for several highly specialized pieces of testing equipment.
• Assist the Bituminous Mixtures Engineer with daily laboratory operations, including scheduling, training, instruction, and inspecting the work of Bituminous Mixtures Laboratory staff.

To be considered for these opportunities, the following competencies are required:

• Technical Materials Testing: Experience performing complex laboratory testing, utilizing data acquisition systems and laboratory software, maintaining and calibrating equipment, and supporting or leading technical work in a laboratory setting.
• Materials Testing & Analysis: Demonstrated knowledge of materials testing principles and practices, including physical and mechanical testing of bituminous or comparable materials, with the ability to conduct complex tests using precision instruments and interpret results to evaluate material performance.
• Quality Assurance & Laboratory Standards: Knowledge of quality assurance and control methodologies, laboratory safety practices, and technical documentation standards, with the ability to ensure compliance, maintain accurate records, and support quality reviews and audits.
• Safety & Work Environment Adaptability: Ability to work safely in a laboratory environment with exposure to heat, asphalt materials, chemicals, and heavy equipment, while maintaining a clean and organized workspace. Ability to follow all standard operating and testing procedures and pre-activity safety plans.
• Data Analysis & Technical Reporting: Proficiency in statistical and analytical methods, data management principles, and laboratory software tools, with the ability to accurately analyze, validate, and report test data, identify trends or discrepancies, and prepare clear technical documentation.
• Equipment Calibration & Maintenance: Knowledge of equipment calibration, verification, and maintenance requirements, with demonstrated experience to maintain, troubleshoot, and ensure proper functioning of laboratory testing systems and associated records.
• Problem Solving & Technical Judgment: Str…
