EVALUATION OF CONSTRUCTION CONTROL PROCEDURES

The purpose of this study was to evaluate variations inherent in aggregate gradations. The research developed data relative to variations normal to coarse aggregate gradations at different points in the process stream at various types of plants at widely different geographical locations. Statistical techniques were used for determining the relative effect of testing accuracy, sampling methods, and segregation with relation to the evaluation and acceptance of coarse aggregate used for highway construction. The work also included the development of a precision statement for the aggregate gradation test and a method of drafting a realistic and adequate acceptance gradation specification for coarse aggregates.
