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," J. of Trans. Engr., 1995: 476-484) employed a least squares analysis in studying how y = porosity (%) is related to x = unit weight (pcf) in con- crete specimens. Consider the following representative data: x 99.0 101.1 102.7 103.0 105.4 107.0...

3. No-fines conerete, 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 for No-Fines Concrete Parking Lots" (J. of Transportation Engr., 1995: 476-484) evaluated the relationship between Y = porosity (%) and X unit weight (lb/ft) in concrete specimens. Summary data resulting from the study is provided below - - = -471.5 lb/ft2-% n 15 =1640.1 lb/ft SK6.1 lb/ft i=1...
