Since the first Asphalt Plant Technician School, many technical advancements have been made to the aspects of producing and testing Asphalt materials, however the role of the Asphalt Technician remains unchanged. An asphalt plant technician, whether a WVDOH employee or a producers employee, is responsible for the quality of asphalt concrete and its essential materials produced at the mixing plant. This includes but is not limited to the handling, storing, stockpiling, mixing, hauling, sampling, and testing of all asphalt concrete materials. Asphalt Plant Technicians are responsible for checking material sources,grades,types,temperatures,moisture contents, truck beds and tarps, verify scale checks, monitor plant operations and mixing time, observe condition of mix in the truck, load tickets for proper information, and review materials documentation and test reports. Along with the plant and yard monitoring, technicians must be able to properly perform the sampling and testing necessary to measure the quality of the materials. Technicians must also be fully capable of reviewing and interpreting mix design data, laboratory test results, and specifications.
