Expansion Joint Between Asphalt And Concrete

If you re stuck with an asphalt parking lot the best approach is to pave a concrete apron around the building with a slope that will ensure adequate drainage away from the building.

Expansion joint between asphalt and concrete.

Thoroughly compact the subgrade and base material adjacent to the apron and slope the asphalt lot to minimize water penetration at the joint. In the past some engineers used combinations of expansion and contraction joints in an attempt to re lieve compressive stresses. Fibre expansion joint ceramar sponge rubber expansion joint cork expansion joint and self expanding cork expansion joint should be recessed 1 2 12 7 mm below the concrete surface to accept the joint sealant. Asphalt expansion joint is composed of a blend of asphalts vegetable fibers and mineral fillers formed under heat and pressure between two asphalt saturated liners.

When i called sika the company that makes the self leveling sealant for this kind of project they told me to use a utility knife to remove old material and clean off any remaining residue with acetone. A sealant is not required. Contraction joints a re placed between the expansion joints. When this happens weeds and grasses take root in the gap.

Asphalt expansion joint should be recessed 1 4 6 35 mm below the concrete surface. Because expansion joints are an important factor in maintaining the integrity of concrete and asphalt surfaces such as roads sidewalks and driveways expansion joint repair is a key factor in keeping these surfaces from cracking and breaking up. Expansion joints like other construction materials eventually need to be repaired or replaced. By william machin over time the wood or composite expansion joint that separates concrete and an asphalt surface can deteriorate.

It is waterproof permanent flexible and self sealing. Expansion joints pavement expansion joints are full depth full width transverse joints placed at regular intervals of 50 to 1 500 feet.
