<p>The paper provides an outline of important points that need to be recognized and understood when selecting material for use in embankment dams. It covers soil materials; rockfill materials; granular filters and drains; asphalt concrete as a water barrier; ...

RCC is batched and mixed onsite using a portable mixing plant. Occasionally, one or more aggregates are obtained on or near the site and graded to conform to the specified aggregate gradation. It is more common to purchase aggregates from an aggregate supplier ...

<p>These guidelines describe the design and construction requirements for the construction of a proposed dam or the reconstruction, modification, enlargement, rehabilitation, alteration, or repair of an existing dam in Texas. These design and construction ...

Nam Ngum 2 dam, a large concrete face rockfill dam (CFRD) of 182 m height, is under construction and impounding is scheduled to start at beginning of April 2010. The dam is situated in a narrow valley and founded on sedimentary rock of variable strength. Dam ...

<p>The design of small dams constructed of roller compacted concrete (RCC) can be more challenging than the design of a much larger RCC dam. This is especially true when the design engineer has a restricted budget for design and construction of the dam.</p ...

<p>The Guidelines for the Construction of Earth-Fill Dams detail the specifications for the construction of earth-fill dams, and outline the precautions and methods which should be employed in order to obtain the soundest possible structure. These guidelines ...

<p>The main concern when designing or analysing embankment dams is usually their stability. However, assessing their deformation is also important. This paper describes the recent use of advanced numerical analysis to predict the latter. Examples of its use ...

<p>The world&rsquo;s first roller-compacted concrete in dams was started in October 1978 in Japan. Since then, for just 30 years, about 50 roller compacted concrete dams have been constructed in Japan. This rollercompacted concrete is called RCD (Roller Compacted ...

It is the purpose of this paper to show how RCC design and construction techniques were developed with time and how RCC is today applied in a general way at South African dams.

<p>Through a period of years, we met with Robie Lange, Don Pisani, and the team of authors to review drafts and discuss progress. The objectives of the study were twofold: a history of federal dam development, concentrating on key projects and river systems, ...
