Abstract:
Transportation agencies, contractors, researchers, and private vendors are actively looking for new methods and devices

to help make construction and maintenance work zones safer while maximizing mobility. Short-term and short-duration

work zones are no exception, especially as fewer devices can be used in a practical way than in long- term work zones due

to the limited installation time available. Practitioners commonly cite the challenge of using traditional devices for

protection, as installation costs are high relative to the project and it may take longer to install the devices than perform

the planned activities. This situation creates the need for more portable positive protection devices in lieu of traditional

devices (such as temporary concrete barrier or “TCB”) that are commonly used on long-term projects, but can’t be

repositioned easily.

So what do we mean by “portable positive protection?” For purposes of this guide,

this label applies to highly mobile and movable steel barriers that provide

acceptable crashworthy levels of protection – like that of temporary concrete

barrier – but are much more portable and relatively quick to install and remove

when compared to more traditional devices. While temporary concrete barrier is

generally considered a device for use on long term projects (those lasting more than

3 days), the definition of portable for the purposes of this guide is a device that is

feasible for shorter work operations. Portable devices are available that can be

easily placed and removed (or moved from the travel way) to provide protection for

short-term and short-duration operations. Portable devices mentioned in this guide

may be used on long-term projects as well since many of the work zones in use could

vary from short to long duration
