This manual has been developed to provide construction project personnel with information and guidance for field activities relating to materials. This manual complements the Standard specifications for Construction of Roads and Bridges on Federal Highway Projects (FP). When the guidelines or directions set forth in this manual conflict with an FLH contract, the contract shall govern. This manual is intended as general guidance. It sets forth procedures and best practices for testing and verifying materials on a contract. The application of this manual to any particular situation is to be guided by sound engineering principles. This manual does not create enforceable rights. However, a contract may adopt or incorporate by reference any portion of this manual and thereby establish that portion as binding on the parties. The manual is divided into five chapters and six divisions. Chapter 1 – Division 100: Acceptance and Verification Procedures and Material Project Requirements; Chapter 2 – Division 200: Earthwork Testing and Evaluation; Chapter 3 – Division 300: Aggregate Base, Subbase, Aggregate-Topsoil, and Base Stabilization; Chapter 4 – Division 400: Asphalt Pavements and Surface Treatments; Chapter 5 – Division 500: Concrete. Chapter 1 processes and procedures are generally applicable to the categories of materials addressed in Chapters 2 through 5. Chapters 2 through 5 set forth the processes needed to address the categories of materials specifically addressed in each particular chapter.
