Tampa Does It with Mirrors
As one of the nation's fastest growing cities, Tampa needed far more public works dollars. But the traditional source, the real estate tax, can no longer be relied on so heavily,...
Slurry Walls Protect Harvard Square
Harvard Square Station, Cambridge, Mass., had to be rebuilt when Boston's Red Line Subway was extended further out to the suburbs. For the first time, tied back slurry walls...
Pipe Laying Comes Out of the Trenches
Recent developments have shown that trenchless construction offers an effective and economically attractive alternative to conventional excavation. These findings are especially important...
Current Corps of Engineers Concepts for Roller Compacted Concrete in Dams
Since construction of Willow Creek Dam in 1982, Elk Creek Dam in southwest Oregon is the only Corps of Engineers dam to be constructed using RCC that has passed beyond the planning stage...
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...
