elimination of bride deck expansion joints. The constructability of these methods will be evaluated based on experimental testing. A cost analysis will be conducted, and a guide/manual for bridge engineers will be developed. 2. Problem Statement Bridge deck expansion joints are used to allow for the movement of the bridge deck due to
Bridge DesignBridge Deck JointsChoice of Deck Joint. Current practice is to make decks integral with the abutments. The objective is to avoid the use of joints over abutments and piers. Expansion joints are prone to leak and allow the ingress of de-icing salts into the bridge deck and substructure.

Bridge Expansion Joints - Beta TechnicalOVM Modular Expansion Joint system has advantages of good water property, large movement, easy installation and maintenance, long service life, smooth and stable for driving, etc. Modular expansion joints are used when the movements of a bridge exceed the capacity of a single gap joint or a finger type joint. Modular multiple-gap expansion
Bridge Expansion Joints - ftp.dot.state.tx.usBridge Expansion Joint Guide April 2019 . DESIGN Bridge Expansion Joints Guidance Material Item 454 Geometric Constraints Deck continuity is encouraged (joint elimination should be considered) Sealing of joints (typically always recommended) De-icing zones Grade separations Design Criteria Thermal expansion
seals are watertight joints which are used in place of sliding plate joints or finger joints in an attempt to keep water and debris on the bridge deck surface. Refer to Figure 12.7-1 for placement of expansion
Chapter 9 Bearings and Expansion Joints ContentsExpansion Joint Specialist and the State Bridge Design Engineer for recommendations and approval. B. Steel Bridges. Use L-type abutments with expansion joints at the ends for multiple-span bridges. Semi-integral construction may be used in lieu of expansion joints for single span
Evaluation of Silicone Sealants on Bridge Deck 1.1. Expansion Joint Importance for Bridge Decks Bridge deck expansion joints are important to the performance of bridge decks, because they allow for movement of the bridge deck through expansion and contraction while keeping water and debris from getting through to the bridge understructure and causing corrosion.
The generic types of bridge deck expansion joints that are listed in the guide include:Part 2 Buried expansion joint Type 1 Buried joint under continuous surfacing Part 3 Flexible plug joint Type 2 Asphaltic plug joint Part 4 Nosing expansion joint Type 3 Nosing joint with poured sealant and
Finger Expansion Joints - DOSHIN RUBBER ENGINEERING - Doshin Finger Expansion Joints are cantilevered or simply supported steel tooth expansion joints. They are composed of pairs of independent elements with parallel teeth provided in lengths from 3 feet to full roadway widths. The Joints are used to provide support to vehicles as they travel across bridge expansion joint openings.
Goodco Z-Tech expansion joints prevent structural damageGoodco Z-Tech expansion joints are custom-designed and fabricated to accommodate the structural movements of highway bridges, multi-level parking garages as well as various civil engineering works such as dams, airports and others. Expansion joints ensure the continuity of bridge traffic while ensuring a watertight seal on the deck.
A sliding plate expansion joint is a system with steel plates embedded in both the abutment side and deck side of an expansion joint that are then allowed to freely slide over one another to provide a smooth ride for traffic and allow for the required movement of the bridge deck.
SECTION 14:JOINTS AND BEARINGS 14-114.4.6 Finger Joints Finger joints can be used to accommodate moderate to high movement ranges. Finger joints can also accommodate minor rotations and vertical displacements across the joint. Finger joints are fabricated from steel plate, with the fingers sized to maintain minimum spacing and to minimize live load deflections.
