Statistical quality control in portland cement concrete pavements
Quality control for portland cement concrete pavements and their component parts was statistically studied in field project approximately 8 mi long; 200 observations were made of slump, air content, gradation, durability, Los Angeles loss, sand equivalent, fineness, and percent passing No. 200 sieve; typical statistical parameters, i.e., testing, sampling and material variances, standard deviation, and arithmetic mean, were calculated, and frequency distribution curves were drawn; in nearly all cases, arithmetic mean of measured characteristic complied well with specifications.
