• Assist the District Materials Engineer by directing the activities of the laboratory personnel.
• Perform laboratory testing which includes HMA mix verification, including source and consensus properties of the constituent materials which requires the use of the Gyratory Compactor, LA Abrasion test apparatus, ignition oven, warming oven, and specific gravity bench.
• Perform plant inspections (HMA and cement concrete) to ensure compliance with specifications; sample and test aggregates in concrete plants to ensure that the aggregate gradation and fineness modulus are within the specification range; sample and test Hot Mix Asphalt to determine the asphalt content, gradation and specific gravity of the mix using various pieces of laboratory equipment from the ignition oven to sieves to specific gravity bench;
  
  post the results on the appropriate plant form.
• Determine Specific Gravity of HMA cores and HMA loose mix utilizing the specific gravity bench and following AASHTO specifications.
• Determine Specific Gravity of aggregates, per AASHTO Specifications, using various pieces of laboratory equipment and documenting the results on standard report forms.
• Perform soils and aggregate gradations, per AASHTO Specifications, using various pieces of laboratory equipment and documenting the results on standard report forms.
• Perform Proctor Soil testing, per AASHTO Specifications, utilizing our automated or manual proctor soil testing machine, charting the data points derived by testing on the computer to determine the maximum density and optimum moisture content of the soil and indicating those numbers on the appropriate test form.
• Perform Concrete cylinder strength test utilizing our compression testing machine while adhering to ASTM and AASHTO Specifications.
• Utilize the nuclear density gauge to determine in-place densities.
• Assist other District Departments by obtaining HMA cores.
• Provide instruction to new laboratory personnel by reinforcing the standards that must be followed and follow‑up with assessing adherence to standards in their annual performance (EPRS) evaluations.
• Set up, breakdown, and clean up the concrete practical test areas to assist with District’s concrete testing instruction and ACI Field Technician certification testing.
• Attend Pre‑construction Conferences when the District Material Engineer is unavailable; make all in attendance aware of any issues or concerns regarding the materials aspect of the particular project.
• Maintain an open dialog with field personnel regarding their test results.
• Maintain District logs by accurately reporting results.
• Perform routine checks of outstanding material needs status by cross‑referencing item expenditure on SAM with material documentation posted to the Materials Section internet‑based collaborative platform.
• Perform interim reviews on documentation posted to SharePoint for compliance with the requirements on the RMS 360 and MassDOT specifications.
• Keep laboratory equipment and facility clean and operational.
• Prepare and review Materials RMS 360 forms for Construction, Maintenance, and Bridge Contracts.
