In recent years bituminous materials have become tremendously important in the construction of roads
and airfields for both military and civilian use. A basic knowledge of these bituminous materials, their
origin, composition, types, and grades, is essential for an understanding of their use in construction.
Knowledge of the classification and desirable characteristics of the aggregates used in bituminous
construction is also of primary importance to the engineer charged with the responsibility of planning,
designing, and constructing bituminous wearing surfaces.
