In 1987, Congress authorized a 5 year $150 million dollar research program called
the Strategic Highway Research Program (SHRP). SHRP was divided into four major
areas, including the asphalt research program. The asphalt research program was divided
into six major research contracts, one such contract, SHRP-003A was called Performance

Service life prediction models for light-framed wood structures require an extensive quantity of empirical data on deterioration pathologies for the numerous structural components, as well as mechanistic approaches to determine their capacity at various levels of deterioration. The data and models presented in this study satisfy a portion of the...
Impending shortages of high-quality aggregates in areas along the Oregon coast have forced users to search for new sources of supply. A number of feasible methods exist for supplying the affected areas. Three of these alternatives are: (1) importation, either by truck, rail, or barge; (2) the use of good-quality...
The task of obtaining good-quality aggregate for construction is a growing problem for most Oregon coastal communities. Current shortages have forced users to import quality aggregate from areas as far as the Willamette Valley. The practice of transporting aggregate over such long distances is both costly and energy-intensive.
One feasible...
The natural reserves of high quality construction aggregates found along the Oregon coast are being depleted. The impending shortages are compounded by restrictions being placed on existing aggregate sources because of energy. economic, and environmental considerations, and zoning regulations. A current solution for the shortage is to import quality aggregate...
Testing of asphalt binders and asphalt-aggregate mixtures using dynamic
mechanical analysis is becoming popular with improvements in high-speed
computers, precision equipment, and computer software. Researchers are trying
to describe the behavior of asphalt binders and asphalt-aggregate mixtures in
terms of their time- and temperature-dependent linear viscoelastic behavior.
The objectives of...
The thesis is a case study of two traditional family farms that were settled in
Oregon in 1850 and 1915. The study embraces the theory that material culture
reflects customs and values. The material culture indicators within the study are the
architectural structures of the Oregon farms. The study filters...
