Hong Kong's Wastewater Underground
Standard Hong Kong methods for siting the new $18 million Stanley Wastewater Treatment Plant in Hong Kong Island's South District were running into trouble. The rocky coastal...
Calendar: Bridges 1994
Featured bridges are: Briggs Bridge (AK); Stone Arch Bridge (NY); Rio Grande Gorge Bridge (NM); Bridge Street Bridge (MI); Hennepin Avenue Bridge (MN); Egypt Pike Bridge (OH); William...
In-Service Durability Evaluation of Armourstone
A summary flow diagram for rock evaluation, general to all rock types and engineering applications of rock is introduced. It is then applied to armourstone. Increasing detail within this...
Laboratory Testing of Stone for Rubble Mound Breakwaters: An Evaluation
The quality of the final stone product hinges on the combination of two factors - rock properties and environmental conditions. The environmental conditions associated with production...
Physical Model Testing of Broken Armor Stone
Cracking, breaking into two or more pieces, flaking, crumbling, and abrading may reduce an armor stone to a size where wave action can remove it from the structure causing a local instability....
U.S. Experience With Armor-Stone Quality and Performance
In the past 30 years problems with deterioration and cracking of armor stone in the United States have been concentrated in northern regions, particularly around the Great Lakes. The explanation...
Improving Stone Placement Specifications
Thorough preparation of stone placement specifications can go a long way toward keeping projects on track. But developing well-prepared placement specifications is not easy. It requires...
Stability of Rock Armour Under Random Wave Attack: Performance of Non-Standard Rock Shapes and Gradings
Quarried rock is frequently used to protect coastal and shoreline structures against wave attack. Armour rock specifications generally exclude rock that is rounded or tabular, and gradings...
The Assessment of Armourstone for Shoreline Protection
To protect shorelines from erosion, Ontario Hydro is using armourstone at various Generating Stations along the perimeter of the Great Lakes. Armourstone is carefully evaluated prior to...
Service Records of Chicago District Breakwater Stone and How These Relate to Test Results
Breakwater stone production is limited to areas with geologic outcrops capable of producing large rocks. The most reliable breakwater stone is that which exhibits the highest degree of...
Problems With Armor-Stone Quality on Lakes Michigan, Huron, and Erie
The instances of deterioration of armor stone at coastal structures on the Great Lakes result from numerous distinct causes, both intrinsic and extrinsic. However, the proof of specific...
An Example of Rubble Mound Construction Procedures
The Gold Coast of Queensland, Australia, is in an exposed coastal zone that is now suffering from major problems with both the availability of suitable large rubble armour and its durability...
Quartzite?A Hard Rock Approach to Rubble Mounds
The quality of stone in rubble mound structures has always been a concern but seems to be more so the past few years. Breakwaters built in the 1920's using granite armour...
Pricing Armor Rock for Rubble Mound Breakwaters
The pricing of armor rock by breakwater contractors is an inexact exercise. Each breakwater project is so site specific that standard costing methods are difficult to apply. The wide range...
Quarry Techniques for Dimensional Breakwater Stone
On the Texas Gulf Coast, there has evolved a unique design for breakwater and jetty structures. The Galveston District of the U.S. Army Corps of Engineers, the designer of these structures,...
Quarry Inspection: A Geological Perspective
The need to use durable rock in building projects is becoming more critical as the costs of labor and materials rise. The Steering Committee of the 1991 Quarried Rock For Rubble Mound...
Producing Armourstone Within Aggregate Quarries
This paper discusses a series of full-scale trial blasts which was conducted in an aggregate producing quarry with the objective of improving yields of armourstone. The quantitative research...
Some Case Histories of Armor Stone Production
The blasting techniques used to produce armor stone, derrick stone, and underlayer stone [one to twenty tons] for the construction of rubblemound breakwalls and the confined Dike Disposal...
