Selection of materials is very important in bridge construction as in any structural project Early wood or vine bridges would eventually rot which means a mixture of both iron and carbon that …
Prevention and control of degradation process is achieved by effective maintenance methods applying protection technology such as paints, coating and cathodic protection. The purpose of this chapter is to show a brief review of ancient and modern bridges, including the process of design, material selection, construction, and maintenance.
The most common building materials found in Truss bridges are timber, iron, steel, and concrete. ... With so many types of bridges, the construction process varies. Building a bridge is a long and tedious project that can take years to complete depending on the size and other factors. ... Construction Equipment and Tools: Bridge construction ...
Bridge Construction Materials: The traditional building materials for bridges are stones, timber and steel, and more recently reinforced and pre-stressed concrete. For special elements aluminum and its alloys and some …
Most modern bridges use concrete and steel as base material for the pile. Decking . The most visible and used section of the bridge is its decking component, which serves as the road or surface for vehicles to travel on [1]. For RC bridges, the decking is made of concrete poured over a metal framework that serves to strengthen the entire assembly.
A bridge abutment is a unique structure located at the ends of an overpass span connecting the bridge's deck to the ground. It supports the weight of the platform vertically and horizontally. So, the bridge conveys importance to the bridge's foundation from the superstructure at the end of the bridge. It plays the role of retaining the ...
Equipment used in bridge construction includes bridge access machinery like cranes and aerial lifts. It also comprises excavators for digging trenches and hauling equipment like skid loaders and telehandlers. Also, hydro platforms enable below bridge access while light towers offer extra lighting. Bridges come in a wide range of sizes and ...

Piling. The most common way to construct a deep foundation for a bridge is called piling. Long, narrow posts called piles are hoisted into the air by a crane and driven into the ground by a large hammer called a piledriver (not …
Bridges Built. Mechanized bridge construction is based on the use of specialized erection equipment. Beam launchers are used to erect precast beams. Self-launching gantries and lifting frames are used to erect precast segmental bridges. Forming carriages are used for segmental casting of the concrete slab of composite bridges.
Both bridges took two 8-month construction seasons to build CLCA uses rectangular cross-section tubular steel arches filled with concrete to act as the false work to form the reinforced …
Backhoes. A backhoe is another piece of bridge construction equipment that is essential in creating a strong foundation for a bridge. Like excavators, they can dig holes and trenches for the abutments and piers of the bridge. Much like skid loaders, they can move dirt and rock and backfill holes as needed on site.
The determination of the bridge design takes place by the type of bridge whose construction is to take place. The main types of bridges are arch, cantilever, truss, beam, and suspension. Moreover, categorization of the bridges can take place by the planned use, pedestrian pavement, material to be used like concrete or steel, and moveable or fixed.
Aerial Lifts. Aerial lifts are also among the best equipment for bridge construction. This equipment provides workers with safe access points during all stages of bridge construction. Aerial lifts provide extra height for certain spots on the bridge, like the bridge deck. Aerial lifts have their own limitations too.
