Wood and Wood-Based Materials: Current Status and Future of a Structural Material
Wood is one of the earliest construction materials, and the structural use of wood and wood-based materials continues to steadily increase. In fact, new wood-based materials continue to...
Use of Fiber Reinforced Polymer Composites as Reinforcing Material for Concrete
Although the potential of continuous fiber reinforced polymers (FRPs) was recognized more than 50 years ago, bottlenecks such as vulnerability to static fatigue, ultraviolet radiation,...
History of Hot Mix Asphalt Mixture Design in the United States
Asphalt has been used as a construction material from the earliest days of civilization, but though it has long been used as a waterproofing material in shipbuilding and hydraulics, its...
Fiber-Reinforced Polymer Composites for Construction�State-of-the-Art Review
A concise state-of-the-art survey of fiber-reinforced polymer (also known as fiber-reinforced plastic) composites for construction applications in civil engineering is presented. The paper...
Preparing for Takeoff
New Hampshire's Manchester Airport laid the groundwork for steady grwoth with a set of infrastructure projects including the construction of a parking garage, a terminal expansion,...
A Better Barrier
Seepage problems have troubled the Walter F. George Lock and Dam, on the Chattahoochee River, for more than 40 years. Construction of a deep positive cutoff wall is nearing completion,...
