What are the types of crack sealants applied in crack sealing?

Crack sealing, also known as crack filling, is a significant step in lengthening the lifespan of your asphalt. There are two primary causes of cracks in your asphalt. The initial one is base erosion; as the base settles underneath the asphalt, it is essential to seal these cracks with an ideal crack sealant to prevent the negative impacts of the cracks. In case you do this within the first several years of your asphalt, you can lower the extent of these cracks. By sealing those cracks, you will redirect water to the berm of the asphalt rather than letting the water settle in the base that can result in more erosion.

The second dangerous component is the sun. When a crack occurs, the ultraviolet rays can cause severe damage during the crack’s expansion. Crack sealing acts as a shield against the ultraviolet rays, which can damage the interior walls of a crack. Commonwealth provides you with two primary crack sealants that can be applied depending on the task at hand and the equipment available. They include:

Crack sealing that can be applied depending on the task

• Cold-applied crack sealants. These are perfect for repairing asphalt parking lots, driveways, walking or cycling pathways, and many others. Cold-applied crack sealants are accessible for repairing cracks up to an inch wide. For cracks up to a half-inch wide, typical pourable crack sealants work perfectly. When handling cracks up to an inch wide, it is advisable to advance to a trowel-grade crack sealer. When applying cold-applied crack sealant, ensure the surface temperature and the ambiance are maintained above fifty degrees for twenty-four hours. Also, allow the crack sealant to dry before opening up for use.
• Hot-Applied Crack Sealant. These are accessible for excellent conditions and can vary based on the type of equipment you have. The two distinct types of equipment are oil-jacketed kettles and direct-fire; ensure you inquire from your CommonWealth representative which hot-pour crack sealant would be commendable with your equipment. Besides, many hot-applied crack sealants can be executed on cracks up to three-quarters inches. In a situation where the damage is more than three-quarters wide, you can apply the trowel-grade material. When implementing hot-pour materials, the minimum surface and ambient temperature should be forty degrees that provide you more of an execution window than cold-applied materials.

When using ether form of crack sealant, cracks must be free from loose aggregate, dust, and moisture. Some cracks might require to be cleaned or routed with a wire brush. Additionally, when applying either type of crack sealant, it is usually an incredible idea to follow the execution with a V-shaped or U-shaped squeegee to aid you to ensure an excellent seal to obstruct moisture from more penetrating the cracks.
