What is typically used to fill small cracks in asphalt?

• A. Sealant
• B. Fog seal
• C. Patching compound
• D. Sand filler

Answer: (B)

The typical material used to fill small cracks in asphalt is sealant. Sealants are specifically designed to fill and seal cracks to prevent water infiltration, which can lead to further damage and deterioration of the asphalt surface. They create a flexible bond that can expand and contract with temperature changes, which helps to maintain the integrity of the pavement. While fog seal is primarily used as a surface treatment to rejuvenate and seal the entire asphalt surface, it does not specifically target individual cracks. Patching compound is intended for larger repairs where pieces of asphalt must be replaced, and sand filler is not suitable for sealing cracks as it will not adhere or provide the necessary watertight seal that sealant does. Thus, sealant is the most appropriate choice for effectively filling small cracks in asphalt.
