STATISTICAL ANALYSIS OF COMPACTION DATA FOR CONSTRUCTION CONTROL

A STATISTICAL SAMPLING PLAN IS PRESENTED WHICH WAS DEVELOPED TO ESTIMATE THE COMPACTED CONDITION OF A LAYER WITHIN CONSTRUCTION BLOCKS OF EMBANKMENT, SUBBASE AND BASE COURSE CONSTRUCTION. THE PROCEDURE IS DESCRIBED AS IT WAS USED ON THE AASHO ROAD TEST. A TABLE IS PRESENTED WHICH REPRESENTS THE UNIVERSE FOR THE BLOCK-LIFT. THE FICTITIOUS BLOCK-LIFT IS SAMPLED AND TESTED TO DETERMINE AN ESTIMATE OF ITS COMPACTED CONDITION FOR ACCEPTANCE OR REJECTION. DETERMINATION IS MADE OF THE NUMBER OF SAMPLES THAT CAN BE TAKEN. AN ACCEPTABLE QUALITY LEVEL IS SPECIFIED, WHICH IS SIMPLY THE UNIVERSE PERCENT DEFECTIVE, ABOVE WHICH THE UNIVERSE IS TO BE REJECTED. THE SPECIFICATIONS FOR COMPACTION CONTROL ON THE ROAD TEST SET BOTH UPPER AND LOWER LIMITS ON PERCENT COMPACTION FOR THE EMBANKMENT, SUBBASE AND BASE.
