Climate Control
The Wisconsin Department of Transportation (WisDOT) has created its own customized weather information system to improve efficiency in its winter road maintenance operations. Intended...
The Search for HPC (Available in Structural Engineering Special Issue only)
High-performance concrete (HPC) is often overlooked by engineers because its properties are not well documented. Concrete Clinic International conducted a study to learn more about the...
Shake It Up (Available in Structural Engineering Special Issue Only)
The California Department of Transportation (CALTRANS) has used structural lightweight concrete for more than 45 years in bridges across the state. Lightweight concrete�made with aggregates...
Mitigation of Void Development under Bridge Approach Slabs Using Rubber Tire Chips
The problem of void development under bridge approach slabs has been correlated to the use of integral abutment bridges (Schaefer and Koch, 1992). This void development then causes settlement...
Behavior of Construction and Demolition Debris in Base and Subbase Applications
The design performance of a pavement system is evaluated based on the predicted number of load repetitions it will be subjected to throughout its service life. Mechanistic pavement design...
Repeated Loading of Stabilized Recycled Aggregate Base Course
The fatigue behavior, resilient properties, and progressive accumulation of damage due to repeated flexural loads on a fiber-reinforced pavement base course material composed of cement-stabilized...
Database on Beneficial Reuse of Foundry By-Products
This paper describes a database on beneficial reuse of foundry by-products that was assembled at the University of Wisconsin-Madison. The database was designed to identify (1) materials...

Cure for Thinning Concrete
After placing 75% of the concrete liner for twin 4.6 km transit tunnels in Portland, Ore., engineers discovered areas of concrete that were thinner than the prescribed 305 mm thickness....
Northumberland's Ice Breaker
Extending more than 12.8 km over treacherous waters, the new Northumberland Strait Crossing had to go a long way to finally join the last separate Canadian province to the mainland. Design...
Stressing Masonry's Future
Post-tensioning techniques are expanding the possibilities for masonry in building and bridge construction. Two projects in Britain and the U.S. show the rewards of rethinking approaches...
A Race to Innovate
The annual Concrete Canoe Competition, which is co-sponsored by the ASCE and Cleveland-based Master Builders, fosters several engineering breakthroughs that are ignored or forgotten by...
Concrete Colossus
After finding 120 million cubic meters of oil and 30 billion standard cubic meters of natural gas 175 kilometers off the Norwegian coast, Houston-based Conoco, Inc. was faced with a second...
Better Salt Storage
Facing tighter maintenance budgets and stringent environmental regulations, many highway departments are designing and building innovative structures to store road salt. One such structure...
Manhole Rehab
Using trenchless technology, two construction crews working on the Massachusetts Water Resources Authority's Wellesley Extension Relief Sewer project rehabilitated 83 manholes...
