Design and Construction of Roller-Compacted
Concrete Pavements for Container Terminals (Story follows)
 Roller-compacted
concrete (RCC) is a zero-slump concrete consisting of dense-graded
aggregate and sand, cementitious materials, and water. The use of
RCC as a material to construct pavements began in the 1970’s
in Canada. In the past 25 years it has gained acceptance as a strong
and durable pavement material that can withstand heavy loads and
severe climates with little required maintenance.
The use of RCC for pavements at industrial facilities such as
port and intermodal container terminals is particularly appropriate
because of the ability to construct low-cost concrete pavements
over large areas, allowing flexibility in terminal operations over
time. Two basic pavement designs are used which incorporate RCC:
1) unsurfaced, where high-strength concrete is used as the surface
layer, and 2) asphalt surfaced, where lower-strength concrete is
used as a pavement base and an asphalt layer is used for the wearing
surface.
This paper discusses the design concepts for RCC pavements, including
the materials characterization, evaluation of loads, and thickness
design. Development of the RCC mix design is presented, in addition
to important aspects of pavement construction. Performance of RCC
pavements at container facilities is evaluated, including existing
pavements at the Conley Terminal in Boston, BN Intermodal Terminal
in Denver, Pier 300 at the Port of Los Angeles, and the CN Intermodal
Terminal in Calgary, Alberta.
