An expansion joint in a concrete structure is a separation provided between adjacent sections to allow movement due to dimensional increases and reductions of the adjacent sections and through which some or all of the bonded reinforcement is interrupted. In pavements slabs on ground it is a separation between slabs filled with a compressible ...

Expansion joints in concrete pavement are also seldom needed, since the contraction joints open enough (from drying shrinkage) to account for temperature expansion. The exception might be where a pavement or parking lot are next to a bridge or building—then we simply use a slightly wider isolation joint (maybe ¾ inch instead of ½ inch).

A longitudinal joint occurs in an asphalt pavement when a fresh batch of hot-mix asphalt (HMA) is laid adjacent to an existing lane. It is required to pave the width of a road in multiple lanes because paving the full width of the pavement in a single pass is usually impossible. It is the interface between the two

ASPHALT EXPANSION JOINT is the "original" expansion joint filler. It is composed of a blend of asphalts and mineral fillers formed under heat and pressure between two asphalt-saturated liners. It is waterproof, permanent, flexible, and self-sealing. USES. ASPHALT EXPANSION JOINT can be used in 80% of all control joint applications.

Paul Scott Silicone sealant, a type of joint sealant. Joint sealants are typically fluid, gel, or solid agents used to seal construction gaps in masonry, asphalt, timber, or steel structures.The use of a joint sealant serves the dual purpose of creating a physical barrier to exclude water, air, or dirt while creating an aesthetically pleasing finish to otherwise unsightly joints.

A further object is to provide a metal expansion joint formed to define a ii-shaped groove which may be filled with asphalt and oakum or with asphalt alone, which will permit the expansion or contraction of the concrete. Other objects will appear in the course of the following description.

Expansion Joints: Where, When and How By James M. Fisher, S.E. I n the most basic sense, the need for anexpansion joint in a structure depends on the consequence of not having an expansion joint. Will the lack of an expansion joint hamper or destroy the function of the facility, or cause damage

Definition: The joint spaces, expansion or the concrete joints occurred at the time of construction are filled with sustainable compressible materials. These filler materials used to fill the concrete gaps or spaces are known as joint filler.

®Crete SiliconeSeal system is a high performance expansion joint system uti-lizing a dynamic two-part sealant between impact absorbing elastomeric concrete headers. The flexible header of Wabo®Crete II coupled with Wabo®SiliconeSeal make it an ideal expansion joint system for the new construction or repair of existing joints.

Expansion Joints. An expansion joint is placed at a specific location to allow the pavement to expand without damaging adjacent structures or the pavement itself. Up until the 1950s, it was common practice in the U.S. to use plain, jointed slabs with both contraction and expansion joints (Sutherland, 1956).

The asphaltic plug expansion joint components shall be installed as recommended by the joint supplier. A backing plate if specified on the plans, shall be placed in the joint from curb to curb on the roadway portion of the expansion joint. The plate shall be centered over the joint opening.

Abstract. This specification covers bituminous preformed expansion joint filler for use in concrete construction. This product shall consist of a bituminous (asphalt or tar) mastic composition, formed and encased between two layers of bituminous impregnated felt or two layers of glass-fiber felt.

A longitudinal joint is the interface between two adjacent and parallel HMA mats. Improperly constructed longitudinal joints can cause premature deterioration of multilane HMA pavements in the form of cracking and raveling (Figures 1 and 2). These distresses, caused by relatively low density (high air voids) and surface irregularity at the joints, can largely be avoided through proper ...

That's because joints in asphalt allow for water intrusion which can lead to pavement cracking and potholes. For this reason, paving contractors work …

Expansion joint definition, a joint between two parts of a structure, machine, etc., permitting expansion, as from heat, without structural damage. See more.

Products/Services for Asphalt Impregnated Fiberboard Expansion Joints. Flexible Expansion Joints - (437 companies) Description Expansion joints connect two fixed assemblies or pipes and allow movement due to service load, shock, or thermal cycles. Construction They are made of elastomer, fabric or metal materials and feature...

Expansion Joint Transitions. Expansion joint transitions are essential for ensuring a sealed, safe, and energy efficient building envelope. Continuity of seal at changes in plane and direction, and between expansion joint systems, is achieved when factory-fabricated transition assemblies are specified and installed.

Expansion joints consist of a preformed joint filler, generally 1 in. thick, that compresses and allows the pavement to expand. The joints are placed at the locations noted on the plans. The joint filler is required to be shaped to the subgrade, parallel to the surface, and the full width of the pavement. The edges of the expansion joint are to ...

The exception might be where a pavement or parking lot are next to a bridge or building—then we simply use a slightly wider isolation joint (maybe ¾ inch instead of ½ inch).

define criteria for determination of the expansion joint type and to give technical conditions for its proper design, installation and use. ... Asphalt expansion joint is a term for the wide assortment of expansion joints where the extensible part of an expansion joint is

An expansion joint is a device used to allow for the heat-induced expansion and reduction that takes place in various states of weather. They are designed to: Absorb heat-induced expansion and contraction of construction materials. Absorb vibration. Hold parts together. Allow movement due to ground settlement or earthquakes.

Heretofore, highly satisfactory expansion joints having the above characteristics have been formed from boards composed of fibers securely bonded together and uniformly saturated with asphalt to insure longevity. These fiber expansion joints are typically produced by cutting an asphalt saturated fiberboard into strips of a desired width and length.
