Behavior and load carrying capacity of stump anchors

Creator:: Stoupa, Joan
Abstract:: Research was conducted to study the behavior and load carrying capacity of stump anchors. A field testing program was undertaken to determine the response and strength characteristics of second growth Douglas-fir (Pseudotsuga menziesii) stumps ranging in diameter from 6 to 17 inches. Horizontal and vertical stump movements due to an...

Evaluation of the environmental conditioning system as a water sensitivity test for asphalt concrete mixtures

Creator:: Allen, Wendy L.
Abstract:: The Environmental Conditioning System (ECS) was designed to evaluate the water sensitivity of asphalt concrete mixtures. The ECS subjects asphalt concrete specimens to a series of conditioning cycles including water flow, elevated and/or lowered temperature, and repeated axial loading. The purpose of this research was to: (1) evaluate the ECS...

Selection and performance evaluation of a test method to assess thermal cracking resistance of asphalt-aggregate mixtures

Creator:: Jung, Duhwoe
Abstract:: Thermal distress in asphalt concrete pavements is a widespread problem around the world. Thermal cracking can be divided into two modes of distress: low temperature cracking and thermal fatigue cracking. Low temperature cracking results from extremely cold temperatures; thermal fatigue cracking results from daily temperature cycles. Low temperature cracking is...

Consolidation characteristics of calcareous deep sea-floor sediments from the Panama Basin

Creator:: Kao, Yeoung Ting
Abstract:: Calcareous sediments containing a large percentage of foraminiferal microskeletal tests were taken from sites in the Panama Basin and subjected to an investigation to determine the consolidation characteristics of this type of soil. The consolidation-stress curves and the time rate of consolidation curves in particular were investigated in this study....

Laboratory investigation of the mechanics of raveling soils

Creator:: Saunders, George P.
Abstract:: Oregon's forestry industry has and will continue to be a vital component of Oregon's economy, with twenty-two percent of Oregon's 1986 gross state product and thirty-nine percent of Oregon's 1986 gross manufacturing product related the forestry goods. An integral component to proper management of Oregon's forestry lands is Sustaining the...

Modelling root reinforcement in shallow forest soils

Creator:: Skaugset, Arne E.
Abstract:: A hypothesis used to explain the relationship between timber harvesting and landslides is that tree roots add mechanical support to soil, thus increasing soil strength. Upon harvest, the tree roots decay which reduces soil strength and increases the risk of management -induced landslides. The technical literature does not adequately support...

The Biology and ecology of weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia nuttalliana)

Creator:: Tarasoff, Catherine
Abstract:: Weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia nuttalliana) infest Kentucky bluegrass seed fields of eastern Oregon. Weeping alkaligrass is an introduced species from Eurasia, whereas Nuttall’s alkaligrass is native to semi arid environments of western North America. These species are often referred to collectively as ‘alkaligrass’; however, for farmers...

Patterns and processes of sediment transport following sediment-filled dam removal in gravel bed rivers

Creator:: Stewart, Gregory B.
Abstract:: Dam removal is increasingly viewed as a river restoration tool because dams affect so many aspects of river hydrology, geomorphology, and ecology; but removal also has impacts. When a dam is removed, sediment accumulated over a dam’s lifetime may be transported downstream; and the timing, fate and consequences of this...
