Bridge approaches are normally constructed with reinforced concrete slabs that connect the bridge deck to the adjacent paved roadway. The approach slab is usually supported on one side by the bridge abutment and on the other side by the embankment.
What is bridge approach road?
The approach slab provides a transition between roadway pavement and the bridge. The approach slab acts as an intermediate bridge to span the portion of embankment directly behind the abutment/backwall which was excavated to construct the abutment/backwall.
What is bridge embankment?
Embankment. A raised area, or angled grading of fill used in roadway approaches. Fill. Earth, stone or other material used to raise the ground level, form an embankment or fill the inside of an abutment or pier.

What are parts of a bridge called?
The main components of a bridge are the foundation, substructure, and the superstructure. Each of these core areas have other parts within them. Piles and pile caps are constructed as the foundation of the bridge.
What is a bearing on a bridge?
A bridge bearing carries the loads or movement in both vertical and horizontal directions from the bridge superstructure and transfers those loads to the bridge piers and abutments.
What is abutment in bridge construction?
A bridge abutment is a structure which connects the deck of a bridge to the ground, at the ends of a bridge span, helping support its weight both horizontally and vertically.
What are the three major bridge components?
The main components of a bridge are the foundation, substructure, and the superstructure.
How are bridges inspected?
A geologist hammer and a simple rotary impact tool are used to test bridges. Using a rotary impact tool to “sound” a bridge, inspectors listen for differences in pitches and frequencies that indicate the health of a bridge. A geologist hammer can also be used to sound different areas of the bridge.
What is a bridge construction?
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross.
