Creator:: Chang, Chen
Abstract:: Coastal Oregon is deficient in quality construction aggregate. There is, however, an abundance of lower quality, or marginal aggregate available for construction purposes. The purpose of this report is to develop techniques for upgrading marginal aggregates with portland cement and methods for evaluating the relative performance of these stabilized materials...

Creator:: Evans, Gary L.
Abstract:: The purpose of this report is to address the problem of supplying construction aggregates to Oregon's coastal areas that are currently, or will in the near future, be deficient of good quality materials. This is done primarily by studying methods of utilizing marginal aggregates that are abundantly available in the...

Creator:: Szymoniak, Tom
Abstract:: Some basaltic rocks common in Oregon when incorporated into a pavement structure as the base course aggregate or in the surfacing layer degrade and disintegrate owing to the minerals contained within the rock and the environment in which it is placed. To simulate the chemical degradation of basaltic rocks an...

Abstract:: 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...

Creator:: Burchfield, Robert M., Hicks, Russel G., and Oregon State University. Sea Grant Marine Advisory Program
Abstract:: 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...

Creator:: Burchfield, Robert M., Hicks, Russel G., and Oregon State University. Sea Grant Marine Advisory Program
Abstract:: 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...
