WHY ASPHALT MAINTENANCE MATTERS.
Ignoring a plan for asphalt care cuts the lifespan by up to 50%. A strict asphalt maintenance schedule acts as armor against cracks, potholes, and structural failures. Without it, minor issues turn into costly rebuilds....$4500+ for full parking lot replacements vs. $700 for annual crack filling. Properties with a solid longevity maintenance schedule last 25+ years, while neglected surfaces fail within 8 to 12 years.
ROLL OF PREVENTATIVE MAINTENANCE FOR LONGEVITY.
Think of preventative maintenance as an annual doctor visit for your property. Catching cracks, under 1/4", early stops water from washing out base layers. Applying sealcoating
bi-yearly blocks UV rays that oxidize and brittle surfaces. Proactive steps like joint cleaning/sealing and patching add 7-10 years to asphalt's functional life. Data shows parking lots with a pavement preservation schedule slashes repair costs by 75% compared to reactive fixes.
IMPACT OF ROUTINE MAINTENANCE ON LIFESPAN.
Daily traffic grinds asphalt down at 0.15 inches yearly--but routine maintenance reverses this. Fixing drainage dips within 48hrs stops 90% of subsurface washouts. Sealcoat maintenance scheduled every 2-3 years cuts raveling by 60%, maintaining skid resistance above 45 BPN (British Pendulum Number). Roads following a city maintenance of asphalt plan show 30% fewer rutting incidents post-5 years. Factoring in climate? Cold zones using polymer-modified binders in winter crack repairs boost longevity by 40%.
KEY PARTS OF A PLAN TO MAKE ASPHALT LAST
A strong plan keeps asphalt in top shape for 20+ years. Focus on four core tasks.
SEALCOATING CARE (EVERY 1-2 YEARS)
Sealcoating shields asphalt from sun, rain, and vehicle fluids. Apply coal tar sealer every 2-3 years or asphalt-based sealers every 1-2 years. Costs fluctuate between $.16-$.22 per square
foot. Benefits:
*Blocks UV rays that cause asphalt to become brittle and then crack
*Resists automotive fluid spills
*Restores faded black tone
FIX CRACKS AND JOINT GAPS
Seal cracks under 1/4" with rubberized filler. For gaps over 1/2", clean and will with hot pour crack fill. Best done in dry, 50 degree or greater weather
REPAIR HOLES AND SURFACE DAMAGE
Fix potholes within 48hrs to prevent base layer damage. Methods:
*Cold patch bags
*Infrared patching
*Full-depth replacement
CHECK DRAIN SYSTEMS
Clogged drains cause water to eat away at asphalt bases. Inspect twice a year:
*Clear leaves from catch basins
*Check pipe joints for leaks
*Test flow rates after heavy rains.
