Watertightness and Seepage Control in Roller Compacted Concrete Dams
An unjointed mass of roller compacted concrete (RCC) can easily be proportioned and compacted so that it is essentially impermeable and 'watertight. ' Permeability tests of various field-placed...
Roller Compacted Concrete Pavements in British Columbia, Canada
Roller Compacted Concrete (RCC) pavement is an outgrowth of the traditional cement-treated aggregate base (soil-cement) method of street and highway construction. The major use in British...
Simplified Design and Construction Control for Roller Compacted Concrete
This paper presents a simplified approach to the design and construction quality control of roller compacted concrete (RCC) based on research of previous projects, discussions with experienced...
Construction of Two Spillways Using Roller Compacted Concrete
Roller Compacted Concrete (or RCC) is a relatively new method of construction and in many projects can be a low cost alternate to or foundation for conventional reinforced concrete. The...
Construction of Middle Fork Dam
Recently there has been increased interest in roller compacted concrete (RCC) for use in dams. However, to date there has been very little practical experience in construction. Middle...
Construction of Recent RCD-Concrete Dam Projects in Japan
The Japanese Ministry of Construction has organized a committee which has been promoting research concerning rationalized concrete dam construction. A part of this research is the work...
Upper Stillwater Dam Construction Program

Economic Considerations in Selection of a Roller Compacted Concrete Dam
Roller compacted concrete (RCC) has recently emerged as an economically attractive material for gravity dam construction, replacing the use of conventional concrete and even challenging...
USBR Design Considerations for Roller Compacted Concrete Dams
Current Bureau design criteria for concrete dams are based on analytical methods developed and improved over the years, evaluation of construction methods and post construction materials...
Underground Building Reclaims a Landfill
Oregon's Multnomah County built a road and maintenance facility underground to begin reclaiming an old landfill site. More than 600 precast concrete components make up the...
River Lock Rehab: A Winter's Tale
