Crack sealing and crack filling are two common methods of repairing cracks in asphalt pavement. Both methods have their own advantages and disadvantages, and the best method for a particular situation will depend on the type of crack, the climate, and the budget.
Crack sealing
Crack sealing is a preventive measure that is used to stop cracks from expanding. It involves filling the cracks with a sealant, which is a liquid or semi-solid material that hardens to form a barrier between the crack and the elements. Sealants are typically made from asphalt, rubber, or silicone.
Crack sealing is a relatively inexpensive and easy process, and it can be done by a professional or a DIYer. However, it is not a permanent solution. Sealants will eventually break down and need to be reapplied.
Crack filling
Crack filling is a more permanent solution that is used to repair cracks that have already expanded. It involves filling the cracks with a filler material, which can be asphalt, concrete, or another type of material.
Crack filling is a more expensive and time-consuming process than crack sealing, but it is a more permanent solution. Fillers will not break down as easily as sealants, and they do not need to be reapplied as often.
Choosing the right method
The best way to choose between crack sealing and crack filling is to consult with a professional. They can assess the type of crack, the climate, and the budget to determine the best method for a particular situation.
Here are some additional things to consider when choosing between crack sealing and crack filling:
The type of crack: Cracks can be classified as either "working" or "non-working." Working cracks are actively expanding and contracting, while non-working cracks are not. Crack sealing is only effective for non-working cracks.
The climate: Crack sealing is more effective in climates with mild temperature swings, while crack filling is more effective in climates with extreme temperature swings.
The budget: Crack sealing is a less expensive option than crack filling.
Conclusion
Crack sealing and crack filling are both effective methods of repairing cracks in asphalt pavement. The best method for a particular situation will depend on the type of crack, the climate, and the budget.
