Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

29 APPENDIX B- MAXIMUM DENSITY AND OPTIMUM MOISTURE CONTENT OF ILS SAMPLES AND COMPUTED ASTM E691 STATISTICS

30 Table B-1. Maximum Density (lb/ft3) of three replicates of four aggregate –soil blends in the ILS study and the computed statistics according to ASTM E 691; CC stands for coarse-graded aggregate with clay, CS stands for coarse-graded aggregate with silt, FC stands for fine-graded aggregate with clay, and FS stands for fine-graded aggregate with silt

31 Table B-1. Continued

32 Table B-2. Optimum moisture content (%) of three replicates of four aggregate –soil blends in the ILS study and the computed statistics according to ASTM E 691 ; CC stands for coarse-graded aggregate with clay, CS stands for coarse-graded aggregate with silt, FC stands for fine-graded aggregate with clay, and FS stands for fine-graded aggregate with silt
