No-fines concrete, made from a uniformly graded coarse aggregate and a cement-water paste, is beneficial in areas prone to excessive rainfall because of its excellent drainage properties. the article "pavement thickness design for no-fines concrete parking lots,"† employed a least squares analysis in studying how y = porosity (%) is related to x = unit weight (pcf) in concrete specimens. consider the following representative data. x 99.1 101.1 102.7 102.9 105.2 107.0 108.5 110.7 y 28.6 27.9 27.1 25.4 22.9 21.5 21.1 19.4 x 112.0 112.2 113.4 114.0 115.2 115.5 119.9 y 17.0 18.7 15.8 16.6 12.8 13.5 10.7
