Whose Risk Is It, Anyway?
Near the now-closed Smuggler Mine in Aspen, Colo. toxic lead sits beneath the grass of area residents' yards. A major portion of soil in the area has lead above the EPA action...
Harry Seed, Liquefaction & the Gravel Drain
The late Professor Seed of the University of California at Berkeley established criteria for gravel drain design in a 1977 ASCE paper. Without historical proof for its viability in a real...
Two-Time Winner
After more than a century of service as a major U.S.-Canada rail link, the existing St. Clair River Tunnel between Port Huron, Mich. and Sarnia, Ontario is being replaced by a new tunnel...
Design and Proposed Construction Techniques for Pangue Dam
The paper describes the site conditions, design and proposed construction methods for the 115 m high Pangue Dam, Chile's first RCC dam. Trial mix design work and test embankments...
The Construction of New Victoria Dam, Australia
The paper discusses various aspects of the construction of the New Victoria Dam, a 52 m high, high-paste content RCC dam constructed near Perth, Western Australia. The mix design and its...
Design of Miel II?A High RCC Dam
Miel II Dam is a 141 m high RCC structure designed for the tropical mountains of central Columbia. Interesting features are its height (considerably higher than any existing RCC Dam),...
Roller Compacted Concrete Arch/Gravity Dams?South African Experience
The paper traces the development of roller compacted concrete (RCC) dams in South Africa, and in particular the application to arch/gravity dams. The Department of Water Affairs and Forestry...
Performance of Upper Stillwater Dam
Upper Stillwater Dam was constructed with roller compacted concrete (RCC) and horizontally slipformed facing. This unique construction method for a concrete gravity dam included no contraction...
Roller Compacted Concrete Tailing Retention Dam
A roller compacted concrete (RCC) dam has been designed for gold tailing impoundment in southeast Alaska. To minimize up front capital costs, the curved gravity dam with multiple outlet...
Economic Factors in Roller Compacted Concrete Dam Construction
This paper deals with some of the economic factors that designers and contractors need to consider in the design and execution of an RCC dam. Costs for the RCC portion of the Upper Stillwater...
Mixing and Delivery of Roller Compacted Concrete
Mixing and delivery of RCC are discussed. Both the design aspects such as variability and joint quality, and the construction aspects such as equipment capability and performance are covered....
Construction of Urugua-I RCC Dam
Considerations concerning the RCC construction process and its relation with the design and quality are analyzed. The paper contains topics related to the experience obtained at Urugua-i...
Behavior of Urugua-I Dam
URUGUA-I with its 76 m height is one of the higher lean roller compacted concrete dams. The project includes some outstanding features like the very low cement content and a PVC membrane...
RCC Dam Design Concepts Versus Construction Conditions for Stagecoach Dam
The Stagecoach RCC dam was constructed using current state-of-the-art knowledge and the geotechnical approach to roller compacted concrete (RCC) mix design. The design was prepared in...
Concrete-Faced RCC Dams
In the past 10 years, roller compacted concrete (RCC) has gained wide acceptance as a cost effective material for constructing and rehabilitating dams. Since the first RCC dams had seepage...
Roller Compacted Concrete Mix Design
This paper presents a concise and proven mix design process. It covers all the steps necessary to produce a good roller compacted concrete (RCC) mix design for mass and structural applications,...
RCC Test Specimen Preparation?Developments Toward a Standard Method
As there is no widely recognized standard for the preparation of laboratory test specimens for roller compacted concrete (RCC) mixtures, criteria for developing such a standard are listed....
