Design Guideline for the Reintroduction of Wood into Australian Streams
stable pile depth in the Snowy River study (SKM 2005) is outlined. The inputs used in the run of the LLP99 model were: • single soil layer, • very high flexural stiffness of pile (1,000,000 kN/m). • pile width = 0.3 m (i.e. wooden pile), • shear strength in the absence of lateral stress (for unconsolidated sand 150 kN/m was used), • effective unit weight of soil (15 kN/m), • active lateral effe...
متن کاملFRP Dowels for Concrete Pavements
A Paper for the World Wise Conference 1999 Winnipeg, Manitoba © November 15, 1999 Introduction Joints are used in concrete pavements in order to control cracking due to thermal and environmental conditions. Dowels span joints to transfer load from one slab to an adjacent slab and to provide vertical and horizontal alignment. Currently, smooth epoxy coated steel dowels are placed across transver...
متن کاملConcrete Solutions for Quieter Pavements on Existing Roadways
One of the most pressing issues facing state departments of transportation (DOTs) is highway noise, particularly in urban areas. Where autos are the predominant vehicles on high-speed facilities, most of the noise is generated at the tire-pavement interface. The impact of tire-pavement noise lessens as the percentage of trucks increase and other elements of highway noise—vehicle drive trains an...
متن کاملWOOD PLANING PROPERTIES OF AUSTRALIAN PLANTATION-GROWN Eucalypts
Planing properties of seven Australian plantation-grown eucalypts were evaluated to provide recommendations on how these species should be machined and considered for the manufacture of high quality furniture and furnishings. The surface quality produced for each species was evaluated using eight planing conditions. All species performed well producing equivalent or better results than mature t...
متن کاملOn the fracture of highway pavements
A B S T R A C T Using a model of a single layered foundation to describe a highway or an airfield pavement and an integral formulation, the problem of a pavement containing on-the-top layer a crack of finite length 2c is solved for the stress distribution around the crack tip. The analysis shows that the stresses possess the usual 1/e 1⁄2 singular behavior which is characteristic of crack probl...
