Title: HMA PRODUCTION FACILITIES: TRAINING FOR THE MOVE TO QC/QA
Abstract: The nature and level of responsibility of individuals involved in the production and placement of hot-mix asphalt (HMA) is changing with the implementation of quality control/quality assurance (QC/QA). To help meet this challenge, a new training course, HMA Production Facilities, has been developed by the National Asphalt Pavement Association. The course is designed to teach participants how HMA plants operate and how the operation of these facilities affects the quality of the mix. Some of the key elements common to both batch and drum plants discussed in the course are aggregate stockpiling, aggregate feed systems, dryers, asphalt metering, emission control equipment, and surge storage equipment. Elements specific to batch or drum plants are discussed in separate sections. A section of QC/QA discusses elements of a QC plan.
