CHAPTER 8 ASPHALT PLANT SUPERVISOR The Naval Construction Force (NCF) uses various makes and models of asphalt plants in both the Atlantic and Pacific Fleet deployment sites. As an asphalt plant supervisor, you are a key member and share the responsibility for producing a quality mix. You must be aware of all operational functions of the plant and bring to the attention of the Alfa company operations chief any detected problems or potential problems. Additionally,     you     must     be     aware     of     all federal, state, and local regulations and ordinances relating to the operation of the plant, such as air and water pollution restrictions, anti noise requirements, restricted hours of operation, and so forth.

ASPHALT PLANT SUPERVISOR RESPONSIBILITIES This chapter presents the basic information concerning the operations of asphalt   plants   and   the   production   and   uses of    bituminous    materials.    The    Seabees    need well-qualified personnel to operate and maintain asphalt plants. To ensure personnel are qualified, you must emphasize on-the-job training programs. Also, personnel must gain a thorough understanding of the manufacturers’ operator   and   maintenance   manuals. An    asphalt    plant    is    an    assembly    of mechanical, computerized, electronic equipment     where     aggregates     are     blended, heated,    dried,    and    mixed    with    asphalt    to produce a hot-asphalt mix that meets specified requirements. An asphalt plant can be small, large, stationary, or portable. Whatever the size or configuration, every plant can be categorized as either a batch asphalt plant (fig. 8-1), a continuous-flow Figure 8-1.—Batch asphalt plant. 8-1
