Which equipment is recommended for surface cleaning?

• A. Power broom or street sweeper; may need to clean using water spray.
• B. Hand broom only.
• C. Jet washer at high pressure only.
• D. No cleaning is necessary.

Answer: (A)

Efficient surface cleaning needs equipment that can quickly remove loose material from a pavement without harming the surface. A power broom or street sweeper fits this role because it can cover large areas and lift debris such as dust, grit, and leaves in a controlled way. Adding water spray as needed helps control dust and washes away fine material that sweeping alone might miss, resulting in a cleaner surface that adheres better to tack coats or new asphalt overlays. Using just a hand broom isn’t practical for road-scale cleaning, and a high-pressure jet washer can damage the surface or push fines around rather than removing them effectively. Skipping cleaning altogether would leave debris that can compromise adhesion and performance.
