Book excerpt: S2Many foresters and loggers believe that trafficability, or resistance to rutting, improves with time after logging roads are built. However, no one has attempted to quantify the changes or identify the processes involved. In this study, dry density and moisture content of the surface foot of soil were measured at 315 locations on two roads in the central Appalachians over a 30-month period. Density increased slightly during the measurement period at most locations. Almost all of the density changes occurred during the first few months after construction. Moisture content decreased during the first few months after construction, then fluctuated with precipitation amounts. S3.

Book excerpt: S2Three system 6 mill-size alternatives were designed and evaluated to determine their overall economic potential for producing standard-size hardwood blanks. The study focused on developing standard discounted cash flow measures. Internal rates of return ranged from about 15 to 35 percent after taxes. Secondary effort was directed at providing accounting cost summaries to facilitate cost comparison of standard-size blanks with rough-dimension stock. Cost per square foot of blanks ranged from about $0.88 to $1.19, depending on mill size and the amount of new investment required.S3.
