Modern concrete mix designs can be complex. The choice of a concrete mix depends on the need of the project both in terms of strength and appearance and in relation to local legislation and building codes.
The design begins by determining the requirements of the concrete. These requirements take into consideration the weather conditions that the concrete will be exposed to in service, and the required design strength. The compressive strength of a concrete is determined by taking standard molded, standard-cured cylinder samples.

Geosynthetics for Roadway Construction

Geosynthetics for Roadway Construction

Ever since the Romans used palm fronds and other plant fiber matting to reinforce the sub-bases of their famous roads, fabrics have been used to improve road longevity and performance. Modern road construction methods rely on a family of materials called geosynthetics to achieve the same results. But these more sophisticated materials can

The Brains of the Outfit— Software for Truck Scale Systems

The Brains of the Outfit— Software for Truck Scale Systems

Even the most sophisticated machine needs direction. The optimum control systems eases the burden of human operators while keeping them in the decision making loop. Truck scales may not be the first machinery that comes to mind when discussing sophisticated controls, but these systems employ some of the most advanced

Protecting Ocean Avenue

Protecting Ocean Avenue

The city of Newport, RI, had an existing section of retaining wall along the famed Ocean Avenue that needed to be replaced to ensure continued safe operation of the roadway. The failing 300-foot-long wall was built during the 1930s as part of the Works Progress Administration program. It was a

Long-Lasting Solutions

The concrete path that comes to my front door from the sidewalk showed a crack this summer, and I was annoyed, thinking such features of a residence should never fail. Then I realized that the little path had already lasted, untended, untreated, battered by months of snow and ice each

Bioretention Filters

Bioretention Filters

Bioretention has been in use for two decades. A large body of laboratory and field data provides indications of the performance. It is therefore appropriate to synthesize this information so as to provide insight into when and when not bioretention should be used. This first of two articles on bioretention

Project Profile: Precast Security

Residents of Tulsa, OK, know something about severe rainstorms and the flash flooding that can accompany such events. Recently, the city and its residents came together with a plan to mitigate the costly effects of these floods and the erosion of landowners’ property and property values. A series of existing
