accelerated bridge construction pdf

There is no one ABC technique in use in the United States. Instead, there is a family of
ABC construction and contracting technologies that are in use that cover the majority of
ABC projects. Figure 2-1 shows the most common forms of ABC technologies in use
today as compiled by the Federal Highway Administration as part of the “Every Day
Counts” initiative. This effort is being used to encourage innovation in construction in
order to reduce impacts to the traveling public.

The foundation and wall element
technologies and rapid embankment construction technology are in the early stages of
deployment, while others are mature and in use on a regular basis. It is notable that
some of the construction practices support bridge construction, but are not strictly bridge
elements. The innovative contracting techniques work synergistically with ABC, as well
as other types of construction.
