Neoprene Bridge Bearing Pad

This is typically made of a strong and pliable material such as neoprene—a type of heavy-duty industrial rubber. These pads are placed in between superstructures such as the bridge beam and substructures such as the vertical supports called piers.

Bentonite Powder

Bentonite is a very old clay that has been used as a remedy for many things. The fine powder forms when volcanic ash ages. It's named after Fort Benton, WY, which has a lot of it. But it's found all over the world. It's also known as Montmorillonite clay after a region in France with a large deposit.

Non Woven GEO Textile

Geotextiles are those fabrics used in geotechnical applications, such as road and railway embankments, earth dikes, and coastal protection structures, designed to perform one or more basic functions such as filtration, drainage, separation of soil layers, reinforcement, or stabilization.

Water Stopper

A waterstopper is an element of a concrete structure, intended to prevent the passages of fluids (such as water) when embedded in and running continuously through concrete joints. Waterstopper are grouped in two distinct categories.

HT Stand

A Steel member that is prestressed and embedded in concrete, loses the initially applied stress exponentially with the passage of time. The utmost important factor attributing to this loss in stress is the stress relaxation property of the steel itself.

Admixture

An admixture is a material other than water, aggregates, cementitious materials, and fiber reinforcement, used as an ingredient of a cementitious mixture to modify its freshly mixed, setting, or hardened properties and that is added to the batch before or during its mixing.

Anchorage

A safe anchor point is established when the Miller Grip Anchor is inserted into a properly-sized: cured concrete hole. Designed for use in cured concrete with a compression strength of at least 3:000 psi (20.7 MPa) : it can be used for vertical or overhead/ceiling surface applications.

Sheating Pipe

Sheathing creates the necessary void in the structure in which the pre-stressing steel (H.T. Strands) is free to move during stressing after the achieve concrete strength. ... It should be ensured that while placing of vertical steel, the path of sheathing pipe should not get obstructed.

Grout Powder

Grout is a dense fluid which is used to fill gaps or used as reinforcement in existing structures. Grout is generally a mixture of water, cement, and sand and is employed in pressure grouting, embedding rebar in masonry walls, connecting sections of pre-cast concrete, filling voids, and sealing joints such as those between

Expansion Joint

In building construction, an expansion joint is a mid-structure separation designed to relieve stress on building materials caused by building movement induced by: thermal expansion and contraction caused by temperature changes, sway caused by wind. seismic events.

Specification

Plain and laminated elastomeric bridge bearings are designated by hardness (durometer), size, and configuration and, in the case of laminated bearings, by the thickness of the individual layers of elastomer and the size and position of any steel top plates. Furnish bearings produced by a manufacturer prequalified..

Test Report

Where test progress monitoring is about gathering detailed test data, there reporting test status is about effectively communicating our findings to other project stakeholders. Test status reporting is often about enlightening and influencing stakeholders about test results. ...
