Maintenance Requirements for Specific Asphalt Equipment
Different types of asphalt equipment have unique maintenance needs. Here’ s a breakdown of requirements for common machines.
Cold Planers( Milling Machines)
Cold planers, or milling machines, remove existing asphalt layers to prepare a surface for resurfacing. They use a rotating drum fitted with cutting teeth( or picks) that grind and remove asphalt in controlled layers. Keeping the picks sharp and properly aligned ensures a smooth milling process. Dull or damaged teeth lead to inefficient cutting, increased fuel consumption and excessive wear.
Maintenance Requirements:
• Daily: Inspect milling teeth for wear and replace as necessary. Check hydraulic systems for leaks and ensure proper fluid levels.
• Weekly: Clean the conveyor system to prevent material buildup and inspect belts for wear or damage.
• Monthly: Inspect the drum for wear and ensure all cutting tools are securely attached.
Asphalt Pavers
Asphalt pavers place and distribute the asphalt mix evenly. Key components include the hopper, conveyor system, augers and screed.
Maintenance Requirements:
• Daily: Check fluid levels. Inspect the conveyor system, augers and screed for wear or damage. Ensure all safety devices function correctly.
• After Each Use: Clean the screed using a release agent or solvent to prevent asphalt buildup.
• Regular: Lubricate moving parts per manufacturer guidelines.
Compactors( Road Rollers)
Compactors use weight and vibration to compress asphalt, ensuring it bonds correctly.
Maintenance Requirements:
• Daily: Inspect the drum or roller for cleanliness and remove asphalt buildup. Check hydraulic systems and fluid levels.
• Weekly: Inspect the vibratory system and check for loose or damaged components.
• Monthly: Examine operator controls and ensure all gauges function correctly.
Tack Distributors
Tack distributors apply a thin tack coat layer, improving adhesion between asphalt layers. Proper tack application prevents premature cracking and separation.
Maintenance Requirements:
• Daily: Clean spray nozzles to prevent clogging and ensure even application. Check pumps and hoses for leaks or damage.
• Weekly: Inspect and clean filters to maintain proper flow rates.
• Monthly: Calibrate spray systems to ensure accurate application rates.
External Factors: Weather, Inspection and Cost
Knowing equipment parts and functions is the foundation of preventative maintenance, but external factors matter too. Operating in rain, snow or extreme heat accelerates wear, impacts performance and can lead to breakdowns if crews aren’ t prepared. Using hightemperature lubricants in the summer or winter-grade hydraulic fluids in colder
