can be used to seal joints in asphalt pavements because it places very little stress on the asphalt joint face. Asphalt paving materials have low tensile strengths and require a sealant that places very little stress on the asphalt itself while keeping the joint sealed. To …

Specifier Notes: W. R. MEADOWS ® ASPHALT EXPANSION JOINT is composed of cellular fibers securely bonded together and uniformly saturated with asphalt to assure longevity. Wherever a cost-effective joint filler is required, ASPHALT EXPANSION JOINT meets the need. ASPHALT EXPANSION JOINT is versatile, resilient, flexible, and

Expansion joints in concrete pavement are sometimes needed to adequately open the contraction joints. It helps to get an estimate of temperature for expansion. Expansion Joint is made from an element that expands due to variations in temperature.

for joint sealant. Expansion joints Pavement expansion joints are full-depth, full-width transverse joints, placed at regular intervals of 50 to 1,500 feet. Contraction joints a re placed between the expansion joints. In the past, some engineers used combinations of expansion and contraction joints in an attempt to re-lieve compressive stresses ...

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.

In areas where temperature fluctuations are very severe (upper tier of United States), the saw and seal method is ideal for increasing the longevity of asphalt pavement. By installing control joints in the new pavement and sealing the joints, the expansion and contraction process tends to cause many less random cracks in the pavement.

In order to ensure that the cracks do not deteriorate, it is required that the sealant have high adhesion, elasticity, and durability. PU has excellent performance and is widely used in the crack repair of concrete pavement, expansion joint filling of concrete and bridge, . However, the application of PU as repair material in asphalt pavement ...

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).

Expansion joints are full-depth, full-width joints placed at regular intervals along the pavement, usually 50 to 500 ft (15 - 150 m) with contraction joints in between. This is an out-dated practice that allows slabs to migrate and transverse contraction joints to open too wide causing joint …

Current rigid pavement design practice is to eliminate expansion joints by reducing joint spacing as shown below • Joint Spacing o Limit slab length to width ratio to 1.5 maximum For example, − 15' L / 12' W = 1.25 : 1 = ok − 12' L / 15' W = 1 : 1.25 = ok Maximum joint spacing should be 15 feet in all cases

EXPANSION JOINTS 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.

Expansion Joint: A transverse joint located to provide for the expansion of a rigid slab in the longitudinal direction without damage to itself or adjacent slabs. Generally placed near bridges or used to isolate mainline pavement from side road pavement at intersections.

These problems are caused when incompressibles obstruct pavement expansion in hot weather and create compressive pressure along the joint faces. History Sealant use dates back to 1906, when heated tar was first placed between concrete slabs on projects in eastern cities, including Washington, D.C., and Summerville, Mass.
