A Technique for Quantifying Forest Stands for Management Evaluations (open access)

A Technique for Quantifying Forest Stands for Management Evaluations

"In this study, a system for describing the three-dimensional geometry of trees and stands is presented. The system consists of two survey instruments, a theodolite and transit, and basic triangulation principles. A spotting laser has recently been added to the system to facilitate the spotting of the tree nodes to be surveyed" (p. ix). Results show significant differences in tree productivity as a result of fertilization and changes in heights, bole diameters, etc.

Trafficability of Soils: Effects of Surface Conditions on Drawbar Pull of a Wheeled Vehicle

"A study was conducted to (a) investigate the effects of soil surface conditions on one-pass drawbar pull capabilities of a wheeled vehicle, (b) relate optimum drawbar pull to soil strength as measured by several instruments, (c) develop tentative equations for predicting optimum tractive coefficient, and (d) determine effects of tire characteristics (tread pattern and deflection) on drawbar pull. One hundred and six drawbar pullslip tests were conducted with a 3/4-ton M37 truck at a gross weight of 7240 lb. One tire size (9.00-16, 8-PR), two tread patterns (smooth and nondirectional military), and two tire deflections (15% and 35%) were tested. Surface conditions varied from dry and firm, to wetted with small amounts of water, to flooded. Asphalt surfaces also were tested" (p. xi).

Partial abstract: "The use of low-density cellular concrete, having an oven-dry unit weight of 50 pcf or less, as a backpacking material for deeply buried protective structures was studied. Cellular concrete was found to be suitable for this type of application. A number of physical properties of cellular concrete were determined to provide input to design codes" (p. 4).

Deflection-Coverage Relationship for Flexible Pavements (open access)

Deflection-Coverage Relationship for Flexible Pavements

Summary: "This study was conducted for the purpose of developing a relationship between elastic pavement deflection and pavement performance (number of traffic applications necessary to cause failure). Data for the study were taken from past studies of airfield and highway pavements. A summary of test conditions, failure criteria, and traffic type is given for each data source. A relationship was developed between elastic deflection and the number of coverages of traffic for combined airfield and highway data and for airfield data only. The relationship of wheel load and tire pressure is given, and a multiple-regression equation was determined to predict coverages as a function of wheel load, tire pressure, and deflection" (p. xi).
