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....
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...
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...
The 1984 Major Rehab of the Muskegon Harbor, MI South Breakwater: An Extreme Example of Misguided Design of a Stone Structure
It can be inferred from the Shore Protection Manual that the stability of any coastal structure is increased in proportion to the weights of the armorstones. The south breakwater at Muskegon...
The Optimum Gravity Dam
A method is presented for optimizing the cost of a dam by varying the properties of the material and the shape of the dam to produce the lowest cost water barrier to perform the required...
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 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...
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....
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....
RCC Mixes and Properties Using Poor Quality Materials?Concepcion Dam
This paper discusses aggregate studies, mix investigations, and material property tests for the relatively poor quality materials available for use in RCC at Concepcion Dam....
Design of Pena Colorada Tailings Retention Dam
This paper discusses the details involved in the design of a 66 meter high RCC dam to be used to create storage for slurry from an iron ore mining operation located near Manzanillo, Mexico....
Thermal-Structural Analysis Methods for RCC Dams
Current procedures for evaluating temperature control and the placement of contraction joints in roller compacted concrete dams are not always evaluated with the aid of detailed analysis...
Design of the Boney Falls RCC Emergency Spillway
The Boney Falls Emergency Spillway was designed as a mass roller compacted concrete structure. Alternative designs considered include a fuse plug, lowering the embankment and paving with...
Rehabilitating Small Earth Embankments with RCC
The rehabilitation of existing earth dams using roller compacted concrete (RCC) is gaining wider acceptance in the engineering and construction community. Presented herein is a discussion...
Roller Compacted Concrete III

Dams Going Safely over the Top
Many older dams can't pass updated design floods without overtopping the embankment crest. Conventional upgrade methods, enlarging spillways or raising crests, are expensive....
