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...
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...
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,...
The Durability of Rubble Mound Armour in Service ? A Case Study
Over the past decade, the ongoing monitoring of Gold Coast rubble mound structures in service has demonstrated a serious loss of durability over a period of time in the rock units after...
RCC for Rehabilitation of Dams in the USA-An Overview
The use of roller-compacted concrete (RCC) has rapidly become a powerful new tool in the USA for engineers involved with the rehabilitation of existing dams. Starting in 1980, RCC has...
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...
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...
The Design and Construction of Shuikou Project RCC Diversion Wall
Shuikou Hydroelectric Project, currently under construction on the Minjiang River in the People's Republic of China is a concrete gravity dam having a maximum height of 101...
A Review of Design Criteria for High RCC Dams
The 1980s could be considered to be the decade during which roller-compacted concrete dams came of age. This economic method of construction is sufficiently proven that very large dams...
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...
Lessons Learned from Elk Creek Dam
This is the third of a series of papers published on the design and construction of Elk Creek Dam. The first paper discussed design and construction concepts to provide water tightness...
RCC Dam Construction?A Contractor's View
A contractor's view of RCC dam construction is presented. It begins with the principal construction elements and the challenge created by their interrelationships. Men and...
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...
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...
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....
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...
